            Bug ID: 48020
           Summary: Testagent: Accept a raw command line in Run() as an
                    alternative to argv.
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
          Assignee: wine-bugs(a)winehq.org

Windows applications that have a standard main() entry-point taking in argv and
argc parameters parse their command line the expected / standard way.

But a number of Windows applications parse the command line themselves and
usually do it in a buggy way. This is an issue for TestAgent because the client
side can only send the command to run in the argc/argv format which means
building a command line on the server side in a standard way which may not
match the buggy way the application will then parse said command line.

For instance this is an issue with cmd.exe.
If the client calls Run(["cmd". "/c", "script.bat >Task.log"]) the server will
build a command line of the form '"cmd" "/c" "script.bat >Task.log"' but this
results in cmd trying to run '"script.bat >Task.log' which fails because of the
extraneous double quote.

Note that cmd fails in the same way if given the 'cmd "/c" "script.bat
> Task.log"' command line but then works if given 'cmd /c "script.bat
> Task.log"'.

A mitigating change would be to not put double-quotes only where necessary. But
to be sure to not have more issues TestAgent should allow the client to provide
the raw command line instead of the usual argv array.

This could be done by adding a $RUN_CMDLINE flag which could be a
Windows-specific TestAgent server feature.
