2014-05-21qapi: zero-initialize all QMP command parametersMichael Roth1-1/+1
In general QMP command parameter values are specified by consumers of the QMP/HMP interface, but in the case of optional parameters these values may be left uninitialized. It is considered a bug for code to make use of optional parameters that have not been flagged as being present by the marshalling code (via corresponding has_<parameter> parameter), however our marshalling code will still pass these uninitialized values on to the corresponding QMP function (to then be ignored). Some compilers (clang in particular) consider this unsafe however, and generate warnings as a result. As reported by Peter Maydell: This is something clang's -fsanitize=undefined spotted. The code generated by qapi-commands.py in qmp-marshal.c for qmp_marshal_* functions where there are some optional arguments looks like this: bool has_force = false; bool force; mi = qmp_input_visitor_new_strict(QOBJECT(args)); v = qmp_input_get_visitor(mi); visit_type_str(v, &device, "device", errp); visit_start_optional(v, &has_force, "force", errp); if (has_force) { visit_type_bool(v, &force, "force", errp); } visit_end_optional(v, errp); qmp_input_visitor_cleanup(mi); if (error_is_set(errp)) { goto out; } qmp_eject(device, has_force, force, errp); In the case where has_force is false, we never initialize force, but then we use it by passing it to qmp_eject. I imagine we don't then actually use the value, but clang complains in particular for 'bool' variables because the value that ends up being loaded from memory for 'force' is not either 0 or 1 (being uninitialized stack contents). Fix this by initializing all QMP command parameters to {0} in the marshalling code prior to passing them on to the QMP functions.

2014-05-16qapi: skip redundant includesBenoît Canet1-3/+11
The purpose of this change is to help create a json file containing common definitions; each bit of generated C code must be emitted only one time. A second history global to all QAPISchema instances has been added to detect when a file is included more than one time and skip these includes. It does not act as a stack and the changes made to it by the __init__ function are propagated back to the caller so it's really a global state.

2014-05-15qapi: Replace uncommon use of the error API by the common oneMarkus Armbruster2-100/+128
We commonly use the error API like this: err = NULL; foo(..., &err); if (err) { goto out; } bar(..., &err); Every error source is checked separately. The second function is only called when the first one succeeds. Both functions are free to pass their argument to error_set(). Because error_set() asserts no error has been set, this effectively means they must not be called with an error set. The qapi-generated code uses the error API differently: // *errp was initialized to NULL somewhere up the call chain frob(..., errp); gnat(..., errp); Errors accumulate in *errp: first error wins, subsequent errors get dropped. To make this work, the second function does nothing when called with an error set. Requires non-null errp, or else the second function can't see the first one fail. This usage has also bled into visitor tests, and two device model object property getters rtc_get_date() and balloon_stats_get_all(). With the "accumulate" technique, you need fewer error checks in callers, and buy that with an error check in every callee. Can be nice. However, mixing the two techniques is confusing. You can't use the "accumulate" technique with functions designed for the "check separately" technique. You can use the "check separately" technique with functions designed for the "accumulate" technique, but then error_set() can't catch you setting an error more than once. Standardize on the "check separately" technique for now, because it's overwhelmingly prevalent.

2014-05-15qapi: Replace start_optional()/end_optional() by optional()Markus Armbruster2-5/+3
Semantics of end_optional() differ subtly from the other end_FOO() callbacks: when start_FOO() succeeds, the matching end_FOO() gets called regardless of what happens in between. end_optional() gets called only when everything in between succeeds as well. Entirely undocumented, like all of the visitor API. The only user of Visitor Callback end_optional() never did anything, and was removed in commit 9f9ab46. I'm about to clean up error handling in the generated visitor code, and end_optional() is in my way. No users mean no test cases, and making non-trivial cleanup transformations without test cases doesn't strike me as a good idea. Drop end_optional(), and rename start_optional() to optional(). We can always go back to a pair of callbacks when we have an actual need.

2014-05-15qapi: Normalize marshalling's visitor initialization and cleanupMarkus Armbruster1-15/+12
Input and output marshalling functions do it differently. Change them to work the same: initialize the I/O visitor, use it, clean it up, initialize the dealloc visitor, use it, clean it up. This delays dealloc visitor initialization in output marshalling functions, and input visitor cleanup in input marshalling functions. No functional change, but the latter will be convenient when I change the error handling.

Visitors get passed a pointer to the visited object.

2014-02-17QMP: allow JSON dict arguments in qmp-shellStefan Hajnoczi1-0/+3
qmp-shell hides the QMP wire protocol JSON encoding from the user. Most of the time this is helpful and makes the command-line human-friendly. Some QMP commands take a dict as an argument. In order to express this we need to revert back to JSON notation. This patch allows JSON dict arguments in qmp-shell so commands like blockdev-add and nbd-server-start can be invoked: (QEMU) blockdev-add options={"driver":"file","id":"drive1",...} Note that spaces are not allowed since str.split() is used to break up the command-line arguments first.
