I think, actually, that in 1.2 at least if the System property "user.dir" is
set appropriately that is where the Runtime.exec() takes place. I modified
Interp.setWorkingDir() appropriately (which is called by CdCmd.java):
if (dirObj.isDirectory()) {
workingDir = dirObj;
System.setProperty( "user.dir", dirObj.getPath() );
} else {
throw new TclException(this,
"couldn't change working directory to \""
+ dirObj.getName() + "\": no such file or directory");
}
If this was the only problem with the Runtime.exec() this should solve it.
If I remember correctly, however, it was more complicated than that in early
versions of 1.2. Didn't it hang due to the I/O thread hanging?
