LXR Exercise
Searching the "Clear Private Data" feature. By Mohamed, Man, and Mark.
Documentation
Searched "Clear Private Data" in LXR for Mozilla 1.8.0 branch.
Found "/browser/locales/en-US/chrome/browser/browser.dtd, line 169 -- <!ENTITY clearPrivateDataCmd.label "Clear Private Data">", line 169 which did not help us. This file seems to describe the browser labels and buttons, but it does not link to code.
Found "/browser/locales/en-US/chrome/help/menu_reference.xhtml, line 351 --Clear Private Data...
" which gives us some xml tag id which may help. Going to search that tag. We found anothe route.Found "/browser/locales/en-US/chrome/browser/browser.properties, line 106 -- sanitizeButton=Clear Private Data Now". The sanitize button seemed interesting, so we searched that and got:
104 # Sanitize 105 sanitizeWithPromptLabel=Clear Private Data... 106 sanitizeButton=Clear Private Data Now
Found "/browser/base/content/sanitize.xul, line 75 -- document.documentElement.getButton("accept").label = bundleBrowser.getString("sanitizeButton");". sanitize.xul seems to link the button to some javascript source. We will search sanitize.js and see if that brings up anything interesting.
In sanitize.js we found some javascript code that seems to link to c++ code.
151 cookies: {
152 clear: function ()
153 {
154 var cookieMgr = Components.classes["@mozilla.org/cookiemanager;1"]
155 .getService(Components.interfaces.nsICookieManager);
156 cookieMgr.removeAll();
157 },
158
159 get canClear()
160 {
161 var cookieMgr = Components.classes["@mozilla.org/cookiemanager;1"]
162 .getService(Components.interfaces.nsICookieManager);
163 return cookieMgr.enumerator.hasMoreElements();
164 }
165 },
We'll search "nsICookieManager" and found a "/netwerk/cookie/public/nsICookieManager.idl".
In "nsICookieManager.idl" we found a link nsICookieManager which links nsCookieServer.cpp.
449 if (!nsCRT::strcmp(aData, NS_LITERAL_STRING("shutdown-cleanse").get())) {
450 RemoveAllFromMemory();
451 // delete the cookie file
452 if (mCookieFile) {
453 mCookieFile->Remove(PR_FALSE);
454 }
455 } else {
456 Write();
457 RemoveAllFromMemory();
458 }
This file is the cpp cookie implementation and it seems the code above removes the cookie. Good learning experience I think we'd all say!
