Sandbox Issue When Launching MiniBrowser Twice with CEF 126

[patrick.rohrbacher]

Hello,

I am encountering an issue related to the Chromium Embedded Framework (CEF 126) while using the MiniBrowser demo application. When I launch the MiniBrowser twice, the Chromium processes start with the following message:
--no-sandbox stability and security will suffer

How can we avoid this problem?

How can we make it possible for two processes to be launched simultaneously?

Hi,

Read the information in these links about the limitations when we try to launch several instances of the same application with a CEF browser :

It's not possible to enable the sandbox in Delphi applications.

Okay, thanks for the response. Here is the solution I implemented, which allows me to have the same cache or less when I run the application only once

function getCacheName(const prefix: String = 'cache'): String;
var
i: Integer;
sDir: String;
begin
sDir:= ExtractFileDir(ParamStr(0));
sDir:= IncludeTrailingPathDelimiter(sDir);
for i:= 1 to 100 do begin
result:= prefix + i.ToString;
if not(FileExists(IncludeTrailingPathDelimiter(sDir + result) + 'lockfile')) then exit;
end;
end;


procedure CreateGlobalCEFApp;
begin
GlobalCEFApp:= TCefApplication.Create;
GlobalCEFApp.cache:= getCacheName();
GlobalCEFApp.EnablePrintPreview:= True;
GlobalCEFApp.EnableGPU:= True;
GlobalCEFApp.LogFile:= 'debug.log';
GlobalCEFApp.LogSeverity:= LOGSEVERITY_INFO;
GlobalCEFApp.UncaughtExceptionStackSize:= 50;
GlobalCEFApp.OnUncaughtException:= GlobalCEFApp_OnUncaughtException;
GlobalCEFApp.ChromeRuntime:= True;
end;
