2014-05-15qapi: Replace start_optional()/end_optional() by optional()Markus Armbruster
Semantics of end_optional() differ subtly from the other end_FOO() callbacks: when start_FOO() succeeds, the matching end_FOO() gets called regardless of what happens in between. end_optional() gets called only when everything in between succeeds as well. Entirely undocumented, like all of the visitor API. The only user of Visitor Callback end_optional() never did anything, and was removed in commit 9f9ab46. I'm about to clean up error handling in the generated visitor code, and end_optional() is in my way. No users mean no test cases, and making non-trivial cleanup transformations without test cases doesn't strike me as a good idea. Drop end_optional(), and rename start_optional() to optional(). We can always go back to a pair of callbacks when we have an actual need.

2012-02-21qapi: add string-based visitorsPaolo Bonzini
String based visitors provide a consistent interface for parsing strings to C values, as well as consuming C values as strings. They will be used to parse command-line options. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
