2014-05-13ShellPkg: Do not mix status when executing a commandOlivier Martin
The function InternalShellExecuteDevicePath() did not differentiate an error occuring during the preparation of an image and an error occurring during its execution. A use case of the issue was when a EFI application was called in a EFI Shell script. If the EFI application was returning an error then the NSH script stopped its execution. While the EFI Shell specification says the script should continue its execution (see 4.2 Error Handling).

2013-12-19ShellPkg: Refactor the RunCommand APIJaben Carsey
This almost completely splits the RunCommand API into sub-routines. - the ProcessCommandLineToFinal API handles replacing the a found alias and any found environment variables. This will redirect "-?" to "help", if necessary. Upon return, the command line is complete and finalized. It may still have redirection in it, and those will get chopped off later (but no further modifications occur). - the SetupAndRunCommandOrFile API handles updating and then later restoring StdIn, StdOut, and StdErr (and removing their information from the command line). It will call into RunCommandOrFile. - the RunCommandOrFile API divides the logic to RunInternalCommand, RunScriptFile, or running an .EFI file directly. - the RunInternalCommand API handles updating and then restoring Argc and Argv. It will run the internal command in between. - the SetLastError API handles updating of the environment variable "lasterror" - the DoHelpUpdateArgcArgv was changed to DoHelpUpdate and now works on the raw command line and not the argc/argv. This allows the processing to be moved earlier. Note this change has the following positive side effects (this eliminates unnecessary step): - Argc/Argv are only updated for internal commands (as they are library based) - no Argv/Argc/StdIn/StdOut/StdErr processing is done for file system changes. - The ProcessCommandLineToFinal API exists and it's critical to the ability to correctly pre-process split ("|") command lines ahead of time to verify their correctness.
