Implicit enum value generation is incorrect
-------------------------------------------
Key: THRIFT-532
URL: https://issues.apache.org/jira/browse/THRIFT-532
Project: Thrift
Issue Type: Bug
Components: Compiler (General)
Affects Versions: 0.2
Reporter: Ying-Yi Liang
Priority: Minor
For languages without native enum support (e.g. Java, PHP...), the Thrift
compiler automatically assigns a value to enum members without explicit values.
The current algorithm assumes explicit values are in ascending order, which
does not always hold...
See below for a violation case:
enum ValueCollision {
TWO,
ONE = 1,
THREE
}
The implicit value of TWO collides with ONE...A simple solution is to make the
smallest implicit value greater than the largest explicit value.
