2014-06-23vmstate-static-checker: script to validate vmstate changesAmit Shah1-0/+345
This script compares the vmstate dumps in JSON format as output by QEMU with the -dump-vmstate option. It flags various errors, like version mismatch, sections going away, size mismatches, etc. This script is tolerant of a few changes that do not change the on-wire format, like embedding a few fields within substructs. The script takes -s/--src and -d/--dest parameters, to which filenames are given as arguments. Example: (in a qemu 2.0 tree): ./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate qemu-2.0.json (in a qemu 2.2 tree:) ./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate -M pc-i440fx-2.0 \ qemu-2.2-m2.0.json ./scripts/vmstate-static-checker.py -s qemu-2.0.json -d qemu-2.2-m2.0.json The script also takes a --reverse parameter to switch the src and dest jsons. This is just a shorthand for reversing the src and dest. The --help parameter shows usage information.

2014-06-23qapi script: add event supportWenchao Xia2-0/+381
qapi-event.py will parse the schema and generate qapi-event.c, then the API in qapi-event.c can be used to handle events in qemu code. All API have prefix "qapi_event". The script mainly includes two parts: generate API for each event define, generate an enum type for all defined events. Since in some cases the real emit behavior may change, for example, qemu-img would not send a event, a callback layer is used to control the behavior. As a result, the stubs at compile time can be saved, the binding of block layer code and monitor code will become looser.

2014-06-09trace: Multi-backend tracingLluís Vilanova3-41/+41
Adds support to compile QEMU with multiple tracing backends at the same time. For example, you can compile QEMU with: $ ./configure --enable-trace-backends=ftrace,dtrace Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system. This patch allows having both available without recompiling QEMU. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

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.

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.

Three out of three methods dereference it unconditionally. I fail to see how this pointer could legitimately be null. All this useless null checking is highly redundant, which Coverity duly reports.

2014-03-03qapi: Fix licensing of scriptsMarkus Armbruster4-8/+8
The scripts carry this copyright notice: # This work is licensed under the terms of the GNU GPLv2. # See the COPYING.LIB file in the top-level directory. The sentences contradict each other, as COPYING.LIB contains the LGPL 2.1. Michael Roth says this was a simple pasto, and he meant to refer COPYING. Let's fix that.

2014-02-28qmp: Check for returned data from __json_read in get_eventsFam Zheng1-1/+6
When QEMU process aborts and socket is closed, qmp client will not detect it. When this happens, some qemu-iotests scripts will enter an endless loop waiting for qmp events. It's better we raise an exception in qmp.py to catch this and make the test script stop.
