[jira] [Updated] (THRIFT-2462) prevent possible stack overflow due
to recursive syntax support
[ https://issues.apache.org/jira/browse/THRIFT-2462?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jens Geyer updated THRIFT-2462:
-------------------------------
Description:
{code:title=Test.Thrift}
namespace * Thrift.Test
struct Foo {
1: Bar bar
}
struct Bar {
1: Foo foo
}
service ThriftTest
{
i32 testRecursive(1: Foo foo);
}
{code}
{code:title=TestClient.cs}
var first = new Foo()
{
Bar = new Bar()
{
Foo = new Foo()
{
Bar = new Bar()
{
Foo = null
}
}
}
};
Console.Write("testRecursive(tree)");
Console.WriteLine(" = {0}", client.testRecursive(first));
Console.Write("testRecursive(ring)");
first.Bar.Foo.Bar.Foo = first; // now let the innermost leaf backpoint to the root node
Console.WriteLine(" = {0}", client.testRecursive(first));
{code}
{code:title=output}
testRecursive(tree) = 4
testRecursive(ring)
Process is terminated due to StackOverflowException.
