2016-07-06qapi: Improve use of qmp/types.hEric Blake1-5/+1
'qjson.h' is not a QObject subtype; include this file directly in .c files that are using it, rather than abusing qmp/types.h for that purpose. Meanwhile, for files that include a list of individual QObject subtypes, it's easier to just use qmp/types.h for that purpose.

2016-03-22util: move declarations out of qemu-common.hVeronia Bahaa1-0/+1
Move declarations out of qemu-common.h for functions declared in utils/ files: e.g. include/qemu/path.h for utils/path.c. Move inline functions out of qemu-common.h and into new files (e.g. include/qemu/bcd.h) Signed-off-by: Veronia Bahaa <veroniabahaa@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-02-08qobject: Document more shortcomings in our number handlingEric Blake1-1/+10
We've already documented that our JSON parsing is locale dependent; but we should also document that our JSON output has the same problem. Additionally, JSON requires finite values (you have to upgrade to JSON5 to get support for Inf or NaN), and our output truncates floating point numbers to the point of losing significant precision that could cause the receiver to read a different value. Sadly, this series is not going to be the one that addresses these problems. Fix some trailing whitespace I noticed in the vicinity.

Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes.

2015-11-26qjson: store tokens in a GQueuePaolo Bonzini1-1/+1
Even though we still have the "streamer" concept, the tokens can now be deleted as they are read. While doing so convert from QList to GQueue, since the next step will make tokens not a QObject and we will have to do the conversion anyway.

2015-06-22qerror: Finally unused, clean upMarkus Armbruster1-3/+0
Remove it except for two things in qerror.h: * Two #include to be cleaned up separately to avoid cluttering this patch. * The QERR_ macros. Mark as obsolete.

2015-06-22qobject: Use 'bool' for qboolEric Blake1-1/+1
We require a C99 compiler, so let's use 'bool' instead of 'int' when dealing with boolean values. There are few enough clients to fix them all in one pass.

2015-05-11qobject: Add a special null QObjectMarkus Armbruster1-0/+3
I'm going to fix the JSON parser to recognize null. The obvious representation of JSON null as (QObject *)NULL doesn't work, because the parser already uses it as an error value. Perhaps we should change it to free NULL for null, but that's more than I can do right now. Create a special null QObject instead. The existing QDict, QList, and QString all represent something that is a pointer in C and could therefore be associated with NULL. But right now, all three of these sub-types are always non-null once created, so the new null sentinel object is intentionally unrelated to them.

2015-05-11qobject: Clean up around qtype_codeMarkus Armbruster1-2/+1
QTYPE_NONE is a sentinel value. No QObject has this type code. Document it properly. Fix dump_qobject() to abort() on QTYPE_NONE, just like for any other invalid type code. Fix to_json() to abort() on all invalid type codes, not just QTYPE_MAX. Clean up Property member qtype's type: it's a qtype_code.

2014-12-10qjson: Drop trailing space for pretty formattingMax Reitz1-4/+6
For the pretty formatting, the functions converting QDicts and QLists to JSON should not print a space after the comma separating objects, because a newline will emitted immediately afterwards, making the whitespace superfluous.

2013-07-26qapi: Anonymous unionsKevin Wolf1-0/+2
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>
2013-04-13qjson: to_json() case QTYPE_QSTRING is buggy, rewriteMarkus Armbruster1-57/+45
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>
