[SOLVED] Assertion fails when navigating to Google Drive

[digory]

To test CEF and my integration into our application, I randomly followed links. When I tried https://drive.google.com, an assertion within CEF failed. Here's the log:-

I tried the same in cefsimple and cefclient example applications, and there it works with no assertion failure. Any ideas what could cause the problem?

[Czarek]

This line in Chromium: https://cs.chromium.org/chromium/src/me ... mium&l=345

What settings and command line flags are you using? Are you using OSR mode?

[digory]

That's not the assertion I meant. That one fails also, but it does not seem to cause any problem. Seems to be related to WebGL. What is OSR mode?

The one that bothers me is this one:

Code: Select all

[1130/161318:FATAL:url_request_http_job.cc(137)] Check failed: false.


Since its FATAL, it will cause the application to shutdown immediately even in Release mode.

[digory]

These are my settings:

Code: Select all

   ::CefEnableHighDPISupport();
   g_Singleton = new KisCefApp();

   ::CefMainArgs mainArgs (hinst);
   nExitCode = ::CefExecuteProcess (mainArgs, g_Singleton, NULL);
   
   if (nExitCode >= 0)
      {
      return nExitCode;
      }

   CefSettings settings;
   settings.command_line_args_disabled = true;
   settings.no_sandbox = true;
   settings.multi_threaded_message_loop = true;
   settings.persist_session_cookies = false;
   settings.persist_user_preferences = false;
   settings.background_color = CefColorSetARGB (0xff, 0xf0, 0xf0, 0xf0);
   
   // log_severity: Define what should be logged
   
#ifdef DEBUG
   settings.log_severity = LOGSEVERITY_INFO;
#else
   settings.log_severity = LOGSEVERITY_ERROR;
#endif

   // log_file, cache_path, user_data_path

   PWSTR strLocalAppDataPath;
   HRESULT hres = ::SHGetKnownFolderPath (FOLDERID_LocalAppData, 0, NULL, &strLocalAppDataPath);

   if (hres == S_OK)
      {
      std::wstring strTmp = std::wstring (strLocalAppDataPath) + L"\\SomeProduct\\cef_log";
      cef_string_utf16_set (strTmp.c_str(), strTmp.size(), &settings.log_file, true);  // true = clone

      strTmp = std::wstring (strLocalAppDataPath) + L"\\SomeProduct\\cef_cache";
      cef_string_utf16_set (strTmp.c_str(), strTmp.size(), &settings.cache_path, true);  // true = clone

      strTmp = std::wstring (strLocalAppDataPath) + L"\\SomeProduct\\cef_user_data";
      cef_string_utf16_set (strTmp.c_str(), strTmp.size(), &settings.user_data_path, true);  // true = clone
      }

   ::CefInitialize (mainArgs, settings, g_Singleton.get(), NULL);

What is OSR mode?

Off-screen-rendering (CefRenderHandler).

Code: Select all

Checked Chromium source code and it seems this is happening in the LogChannelIDAndCookieStores() function. However Chromium master line 137 seem to be different, don't know what Chromium/CEF version you're using. This recent commit might be related: https://bitbucket.org/chromiumembedded/ ... 055bb9418c

I'm currently using 3.2840.1493.g4e029f4 Win32 binary distribution. I tried moving on to 3.2883.1536.ga8ecb19, but I'm having some difficulties: http://magpcss.org/ceforum/viewtopic.php?f=6&t=14721

The failing function seems to be about cookies. I tried commenting out these settings:

Code: Select all

//   settings.persist_session_cookies = false;
//   settings.persist_user_preferences = false;
 

Unfortunately, I still get an assertion failure.

[Czarek]

This was fixed in https://bitbucket.org/chromiumembedded/ ... okiestores
Update CEF version.

[digory]

OK, good to know! Thanks!
