This patch disables the implicit execution of batch files (i.e. path name extension
.bat
or.cmd
, case-insensitive) inProcess.run
on Windows withshell: false
(default). There are no effects on other operating systems.The disabled behaviour is an irrational and potentially dangerous feature of
CreateProcessW
which is not intended forProcess.run
.If you want to run a batch file on Windows, you need to launch it through a shell, either implicitly with
shell: true
or explicitly by runningcmd.exe
with the batch file as argument.The semantics are different on POSIX platforms where you can directly execute a shell script if it has a shebang. The mechanism on Windows works differently, as
CreateProcessW
implicitly injectscmd.exe /c
which changes the semantics of run arguments.A similar approach has been taken by node.js: nodejs/node@64b6777
