Description:
The angel process which monitors and restart the ndbd process would fail to spwan the ndbd in certain circumstances becuase the argv contained additional items in the begining. This could be caused by ndbd.exe in a location with space in the path.

How to repeat:
.

Suggested fix:
Rewrite the spawn logic to use Vector<BaseString> to keep the list of args instead of plain BaseString, thus removing BasseString::argify from the equation.

Documented in the NDB7.0.20 and 7.1.9 changelogs, as follows:

        On Windows, the angel process which monitors and (when
        necessary) restarts the data node process failed to spawn a new
        worker in some circumstances where the arguments vector
        contained extra items placed at its beginning. This could occur
        when ndbd.exe or ndbmtd.exe was located such that the path
        contained one or more spaces.

Closed.
