Issue ID: 20571
Summary: spawnProcess does not find .bat files
Product: D
Version: D2
Hardware: x86
OS: Windows
Status: NEW
Severity: enhancement
Priority: P1
Component: phobos
Assignee: nobody at puremagic.com
Reporter: johnnymarler at gmail.com
When you execute a program "foo" with spawnProcess, it will find "foo.exe" if
it is a file in the PATH environment variable. However, it will not find
programs with the ".bat" extension.
When searching for a program in PATH on windows, all files with an extension
from the PATHEXT environment variable should be checked, i.e.
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC
I've created a small program to demonstrate/reproduce this issue:
import std.file, std.process, std.stdio;
void main(string[] args)
{
if (args.length == 1)
runTest();
else
writeln("running from an exe!");
}
void runTest()
{
const runDir = "C:\\temp\\testworkdir";
const pathDir = "C:\\temp\\testpathdir";
if (!exists(runDir)) mkdir(runDir);
if (!exists(pathDir)) mkdir(pathDir);
chdir(runDir);
const thisExe = thisExePath();
writefln("thisExePath is '%s'", thisExe);
const tempExe = pathDir ~ "\\anexeprogram.exe";
std.file.copy(thisExe, tempExe);
environment["PATH"] = environment["PATH"] ~ ";" ~ pathDir;
writefln("Added '%s' to path", pathDir);
run(["anexeprogram", "recursive"]); // works
const tempBat = pathDir ~ "\\abatprogram.bat";
{
auto batFile = File(tempBat, "w");
batFile.writeln("@echo running from a bat file");
}
run(["abatprogram.bat"]); // works
run(["abatprogram"]); // FAILS
writefln("Success!");
}
void run(string[] args)
{
writefln("Running %s", args);
auto p = spawnProcess(args);
assert(0 == wait(p));
}
