qapi: force a UTF-8 locale for running Python Python2 did not validate locale correctness when reading input data, so would happily read UTF-8 data in non-UTF-8 locales. Python3 is strict so if you try to read UTF-8 data in the C locale, it will raise an error for any UTF-8 bytes that aren't representable in 7-bit ascii encoding. e.g. UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 54: ordinal not in range(128) Traceback (most recent call last): File "/tmp/qemu-test/src/scripts/qapi-commands.py", line 317, in <module> schema = QAPISchema(input_file) File "/tmp/qemu-test/src/scripts/qapi.py", line 1468, in __init__ parser = QAPISchemaParser(open(fname, 'r')) File "/tmp/qemu-test/src/scripts/qapi.py", line 301, in __init__ previously_included) File "/tmp/qemu-test/src/scripts/qapi.py", line 348, in _include exprs_include = QAPISchemaParser(fobj, previously_included, info) File "/tmp/qemu-test/src/scripts/qapi.py", line 271, in __init__ self.src = fp.read() File "/usr/lib64/python3.5/encodings/ascii.py", line 26, in decode return codecs.ascii_decode(input, self.errors)[0] More background on this can be seen in https://www.python.org/dev/peps/pep-0538/ Many distros support a new C.UTF-8 locale that is like the C locale, but with UTF-8 instead of 7-bit ASCII. That is not entirely portable though. This patch thus sets the LANG to "C", but overrides LC_CTYPE to be en_US.UTF-8 locale. This gets us pretty close to C.UTF-8, but in a way that should be portable to everywhere QEMU builds. This patch only forces UTF-8 for QAPI scripts, since that is the one showing the immediate error under Python3 with C locale, but potentially we ought to force this for all python scripts used in the build process.

qapi: Generate separate .h, .c for each module Our qapi-schema.json is composed of modules connected by include directives, but the generated code is monolithic all the same: one qapi-types.h with all the types, one qapi-visit.h with all the visitors, and so forth. These monolithic headers get included all over the place. In my "build everything" tree, adding a QAPI type recompiles about 4800 out of 5100 objects. We wouldn't write such monolithic headers by hand. It stands to reason that we shouldn't generate them, either. Split up generated qapi-types.h to mirror the schema's modular structure: one header per module. Name the main module's header qapi-types.h, and sub-module D/B.json's header D/qapi-types-B.h. Mirror the schema's includes in the headers, so that qapi-types.h gets you everything exactly as before. If you need less, you can include one or more of the sub-module headers. To be exploited shortly. Split up qapi-types.c, qapi-visit.h, qapi-visit.c, qmp-commands.h, qmp-commands.c, qapi-event.h, qapi-event.c the same way. qmp-introspect.h, qmp-introspect.c and qapi.texi remain monolithic. The split of qmp-commands.c duplicates static helper function qmp_marshal_output_str() in qapi-commands-char.c and qapi-commands-misc.c. This happens when commands returning the same type occur in multiple modules. Not worth avoiding. Since I'm going to rename qapi-event.[ch] to qapi-events.[ch], and qmp-commands.[ch] to qapi-commands.[ch], name the shards that way already, to reduce churn. This requires temporary hacks in commands.py and events.py. Similarly, c_name() must temporarily be taught to munge '/' in common.py. They'll go away with the rename.
