Subject: waitpid errors with shell aliases
Message-ID: <CADUYy5vwfOJOFBQ+zUmkrsxGO=E9N5vUbsVRgjBn_MMY2X6H=A@mail.gmail.com>

Hi,

I am using git shell aliases in config and was facing some weird
error. The error is not reproducible in all runs and occurs randomly
between runs...consider the minimal config(alias section) below for
usage idea:

[alias]
    A = "!f(){ \
        ( \
              // implementation
              git \"$1\"; \
        ) 250<dir/tmp; \
    }; f"
    B = "!f(){ \
        ssh <server> <command>; \
    }; f"
    C= "!f(){ \
        git A B; \
    }; f"

when firing "git C" from shell,in some cases(not deterministically reproducible)
i observed weird waitpid errors of the type :

error: waitpid for f(){         ssh <server> <command>;    }; f
failed: No child processes
fatal: while expanding alias 'B': 'f(){       ssh <server> <command>;
     }; f': No child processes
error: waitpid for f(){     (//implementation; git "$1"; )250<dir/tmp;
   }; f failed: No child processes
fatal: while expanding alias 'A': 'f(){        (//implementation; git
"$1"; )250<dir/tmp;      }; f': No child processes
error: waitpid for f(){    git A B;    }; f failed: No child processes
fatal: while expanding alias 'C': 'f(){       git A B;      }; f': No
child processes

can anyone please help as to what could possibly be the reason for this?

Thanks,
Shubham
