try/catch overrides $ErrorActionPreference? #5693
Description
I was very surprised that if the call to 'bar' is done from within try/catch, then its $ErrorActionPreference is ignored.
See the script below. When 'bar' is called errors are ignored as expected, but when doing it within try/catch the errors surface. Is this the expected behavior?
The script below is a simplification of my actual scenario; in my actual scenario 'foo', 'bar' and the call to 'bar' are on different modules/scripts.
function foo($i) {
if ($i -eq 3) {
throw 'error'
}
}
function bar {
$ErrorActionPreference = 'SilentlyContinue'
for ($i = 0; $i -lt 5; $i++) {
Write-Verbose -Verbose $i
foo($i)
}
}
Write-Verbose -Verbose 'No try/catch'
bar
Write-Verbose -Verbose ''
Write-Verbose -Verbose 'With try/catch'
try {
bar
} catch {
Write-Verbose -Verbose $_
}
