QAPISchema._make_implicit_object_type() asserts that when an implicit
object type is used multiple times, @ifcond is the same for all uses.
It will be for legitimate uses, i.e. simple union branch wrapper
types.  A comment explains this.

The assertion fails when a command or event is redefined with a
different condition.  The redefinition is an error, but it's flagged
only later.

Fixing the assertion would complicate matters further.  Not
worthwhile, drop it instead.  We really need to get rid of simple
unions.

Tweak test case redefined-event to cover redefinition with a different
condition.

From: Markus Armbruster @ 2021-08-26 12:32 UTC (permalink / raw)
  To: qemu-devel; +Cc: peter.maydell, Marc-André Lureau

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Instead of building prepocessor conditions from a list of string, use
the result generated from QAPISchemaIfCond.cgen() and hide the
implementation details.

Note: this patch introduces a minor regression, generating a redundant
pair of parenthesis. This is mostly fixed in a later patch in this
series ("qapi: replace if condition list with dict [..]")

  To: qemu-devel; +Cc: peter.maydell, Marc-André Lureau

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Instead of building the condition documentation from a list of string,
use the result generated from QAPISchemaIfCond.docgen().

This changes the generated documentation from:
- COND1, COND2... (where COND1, COND2 are Literal nodes, and ',' is Text)
to:
- COND1 and COND2 (the whole string as a Literal node)

This will allow us to generate more complex conditions in the following
patches, such as "(COND1 and COND2) or COND3".

Adding back the differentiated formatting is left to the wish list.

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Change the 'if' condition strings to be C-agnostic. It will accept
'[A-Z][A-Z0-9_]*' identifiers. This allows to express configuration
conditions in other languages (Rust or Python for ex) or other more
suitable forms.
