* qapi: Fold normalize_enum() into check_enum()Markus Armbruster2019-10-291-7/+2Star
| | | | | | | | check_features() is always called together with normalize_features(). Fold the latter into the former. Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20191024110237.30963-17-armbru@redhat.com>
* qapi: Fold normalize_features() into check_features()Markus Armbruster2019-10-291-8/+2Star
| | | | | | | | | check_features() is always called together with normalize_features(): the former in check_struct() and check_command(), the latter in their caller check_exprs(). Fold the latter into the former. Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20191024110237.30963-16-armbru@redhat.com>

* qapi: Add feature flags to commandsPeter Krempa2019-10-221-15/+20
| | | | | | | | | | | | | | Similarly to features for struct types introduce the feature flags also for commands. This will allow notifying management layers of fixes and compatible changes in the behaviour of a command which may not be detectable any other way. The changes were heavily inspired by commit 6a8c0b51025.

* qapi: Split up scripts/qapi/common.pyMarkus Armbruster2019-10-221-0/+378
The QAPI code generator clocks in at some 3100 SLOC in 8 source files. Almost 60% of the code is in qapi/common.py. Split it into more focused modules: * Move QAPISchemaPragma and QAPISourceInfo to qapi/source.py. * Move QAPIError and its sub-classes to qapi/error.py. * Move QAPISchemaParser and QAPIDoc to parser.py. Use the opportunity to put QAPISchemaParser first. * Move check_expr() & friends to qapi/expr.py. Use the opportunity to put the code into a more sensible order. * Move QAPISchema & friends to qapi/schema.py * Move QAPIGen and its sub-classes, ifcontext, QAPISchemaModularCVisitor, and QAPISchemaModularCVisitor to qapi/gen.py * Delete camel_case(), it's unused since commit e98859a9b9 "qapi: Clean up after recent conversions to QAPISchemaVisitor" A number of helper functions remain in qapi/common.py. I considered moving the code generator helpers to qapi/gen.py, but decided not to. Perhaps we should rewrite them as methods of QAPIGen some day.
