> TsConfig doesn't build with bison 3.0
> -------------------------------------
>
> Key: TS-2108
> URL: https://issues.apache.org/jira/browse/TS-2108
> Project: Traffic Server
> Issue Type: Bug
> Components: Core
> Reporter: James Peach
>
> With bison 3.0, the generated code has changes such that BisonHeaderToC.sed
> no longer edits the generated header correctly.
> TsConfigGrammar ends up looking like this:
> {code}
> namespace ts { namespace config {
> enum TokenType {
> {
> STRING = 258,
> IDENT = 259,
> INTEGER = 260,
> LIST_OPEN = 261,
> LIST_CLOSE = 262,
> GROUP_OPEN = 263,
> GROUP_CLOSE = 264,
> PATH_OPEN = 265,
> PATH_CLOSE = 266,
> PATH_SEPARATOR = 267,
> SEPARATOR = 268,
> ASSIGN = 269
> };
> }} // namespace ts::config
> {code}
> Maybe a more robust solution would be to include the generated header into
> another file that does the namespace.
