2014-02-21qdict: Extract non-QDicts in qdict_array_split()Max Reitz
Currently, qdict_array_split() only splits off entries with a key prefix of "%u.", packing them into a new QDict. This patch makes it support entries with the plain key "%u" as well, directly putting them into the new QList without creating a QDict. If there is both an entry with a key of "%u" and other entries with keys prefixed "%u." (for the same index), the function simply terminates. To do this, this patch also adds a static function which tests whether a given QDict contains any keys with the given prefix. This is used to test whether entries with a key prefixed "%u." do exist in the source QDict without modifying it.

2014-01-22qapi: extend qdict_flatten() for QListsMax Reitz
Reversing qdict_array_split(), qdict_flatten() should flatten QLists as well by interpreting them as QDicts where every entry's key is its index. This allows bringing QDicts with QLists from QMP commands to the same form as they would be given as command-line options, thereby allowing them to be parsed the same way.

2013-11-29qdict: Optimise qdict_do_flatten()Kevin Wolf
Nested QDicts used to be both entered recursively in order to move their entries to the target QDict and also be moved themselves to the target QDict like all other objects. This is harmless because for the top level, qdict_do_flatten() will encounter the (now empty) QDict for a second time and then delete it, but at the same time it's obviously unnecessary overhead. Just delete nested QDicts directly after moving all of their entries.

2013-07-26qapi: Anonymous unionsKevin Wolf
The discriminator for anonymous unions is the data type. This allows to have a union type that allows both of these: { 'file': 'my_existing_block_device_id' } { 'file': { 'filename': '/tmp/mydisk.qcow2', 'read-only': true } } Unions like this are specified in the schema with an empty dict as discriminator. For this example you could take: { 'union': 'BlockRef', 'discriminator': {}, 'data': { 'definition': 'BlockOptions', 'reference': 'str' } } { 'type': 'ExampleObject', 'data: { 'file': 'BlockRef' } } Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2013-05-23json-parser: fix handling of large whole number valuesMichael Roth
Currently our JSON parser assumes that numbers lacking a fractional value are integers and attempts to store them as QInt/int64 values. This breaks in the case where the number overflows/underflows int64 values (which is still valid JSON) Fix this by detecting such cases and using a QFloat to store the value instead.

2013-04-13qjson: to_json() case QTYPE_QSTRING is buggy, rewriteMarkus Armbruster
Known bugs in to_json(): * A start byte for a three-byte sequence followed by less than two continuation bytes is split into one-byte sequences. * Start bytes for sequences longer than three bytes get misinterpreted as start bytes for three-byte sequences. Continuation bytes beyond byte three become one-byte sequences. This means all characters outside the BMP are decoded incorrectly. * One-byte sequences with the MSB are put into the JSON string verbatim when char is unsigned, producing invalid UTF-8. When char is signed, they're replaced by "\\uFFFF" instead. This includes \xFE, \xFF, and stray continuation bytes. * Overlong sequences are happily accepted, unless screwed up by the bugs above. * Likewise, sequences encoding surrogate code points or noncharacters. * Unlike other control characters, ASCII DEL is not escaped. Except in overlong encodings. My rewrite fixes them as follows: * Malformed UTF-8 sequences are replaced. Except the overlong encoding \xC0\x80 of U+0000 is still accepted. Permits embedding NUL characters in C strings. This trick is known as "Modified UTF-8". * Sequences encoding code points beyond Unicode range are replaced. * Sequences encoding code points beyond the BMP produce a surrogate pair. * Sequences encoding surrogate code points are replaced. * Sequences encoding noncharacters are replaced. * ASCII DEL is now always escaped. The replacement character is U+FFFD. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
