Referencing constant values doesn't work with with typedef types
----------------------------------------------------------------
Key: THRIFT-868
URL: https://issues.apache.org/jira/browse/THRIFT-868
Project: Thrift
Issue Type: Bug
Components: Compiler (General)
Affects Versions: 0.4
Reporter: Jeff DeCew
Priority: Minor
Fix For: 0.5
Setting a constant's value to the value of another constant does not work when
the types are typedefs. The workaround is easy, but it devalues the typedef.
Here's my example input:
{code:title=Test.thrift}
// test with strings
const string str_a = "foo"
const string str_b = str_a
typedef string MyString
const MyString mystr_a = "bar"
const MyString mystr_b = mystr_a // results in empty string
// Test with ints
const i32 int_x = 42
const i32 int_y = int_x
typedef i32 MyInt
const MyInt myint_x = 29
const MyInt myint_y = myint_x // causes compiler error - code generator ends
prematurely
{code}
Which erroneously results in the following:
{code:title=Constants.java}
public class Constants {
public static final String str_a = "foo";
public static final String str_b = "foo";
public static final String mystr_a = "bar";
public static final String mystr_b = "";
public static final int int_x = 42;
public static final int int_y = 42;
public static final int myint_x = 29;
public static final int
<<eof>>
{code}
The string typedef fails silently, ignoring the value and using "" instead,
while the i32 typedef successfully parses, but causes the code generator to
error out mid-file. There are clearly two very different symptoms here, but my
gut tells me that they have the same root cause.
