2016-02-16qom: add helpers for UserCreatable object typesDaniel P. Berrange
The QMP monitor code has two helper methods object_add and qmp_object_del that are called from several places in the code (QMP, HMP and main emulator startup). The HMP and main emulator startup code also share further logic that extracts the qom-type & id values from a qdict. We soon need to use this logic from qemu-img, qemu-io and qemu-nbd too, but don't want those to depend on the monitor, nor do we want to duplicate the code. To avoid this, move some code out of qmp.c and hmp.c adding new methods to qom/object_interfaces.c - user_creatable_add - takes a QDict holding a full object definition & instantiates it - user_creatable_add_type - takes an ID, type name, and QDict holding object properties & instantiates it - user_creatable_add_opts - takes a QemuOpts holding a full object definition & instantiates it - user_creatable_add_opts_foreach - variant on user_creatable_add_opts which can be directly used in conjunction with qemu_opts_foreach. - user_creatable_del - takes an ID and deletes the corresponding object The existing code is updated to use these new methods.

2016-02-08qapi: Drop unused 'kind' for struct/enum visitEric Blake
visit_start_struct() and visit_type_enum() had a 'kind' argument that was usually set to either the stringized version of the corresponding qapi type name, or to NULL (although some clients didn't even get that right). But nothing ever used the argument. It's even hard to argue that it would be useful in a debugger, as a stack backtrace also tells which type is being visited. Therefore, drop the 'kind' argument as dead.

2016-02-08qapi: Swap visit_* arguments for consistent 'name' placementEric Blake
JSON uses "name":value, but many of our visitor interfaces were called with visit_type_FOO(v, &value, name, errp). This can be a bit confusing to have to mentally swap the parameter order to match JSON order. It's particularly bad for visit_start_struct(), where the 'name' parameter is smack in the middle of the otherwise-related group of 'obj, kind, size' parameters! It's time to do a global swap of the parameter ordering, so that the 'name' parameter is always immediately after the Visitor argument. Additional reason in favor of the swap: the existing include/qjson.h prefers listing 'name' first in json_prop_*(), and I have plans to unify that file with the qapi visitors; listing 'name' first in qapi will minimize churn to the (admittedly few) qjson.h clients. Later patches will then fix docs, object.h, visitor-impl.h, and those clients to match. Done by first patching scripts/qapi*.py by hand to make generated files do what I want, then by running the following Coccinelle script to affect the rest of the code base: $ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'` I then had to apply some touchups (Coccinelle insisted on TAB indentation in visitor.h, and botched the signature of visit_type_enum() by rewriting 'const char *const strings[]' to the syntactically invalid 'const char*const[] strings'). The movement of parameters is sufficient to provoke compiler errors if any callers were missed. // Part 1: Swap declaration order @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_start_struct -(TV v, TObj OBJ, T1 ARG1, const char *name, T2 ARG2, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type bool, TV, T1; identifier ARG1; @@ bool visit_optional -(TV v, T1 ARG1, const char *name) +(TV v, const char *name, T1 ARG1) { ... } @@ type TV, TErr, TObj, T1; identifier OBJ, ARG1; @@ void visit_get_next_type -(TV v, TObj OBJ, T1 ARG1, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, TErr errp) { ... } @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_type_enum -(TV v, TObj OBJ, T1 ARG1, T2 ARG2, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type TV, TErr, TObj; identifier OBJ; identifier VISIT_TYPE =~ "^visit_type_"; @@ void VISIT_TYPE -(TV v, TObj OBJ, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, TErr errp) { ... } // Part 2: swap caller order @@ expression V, NAME, OBJ, ARG1, ARG2, ERR; identifier VISIT_TYPE =~ "^visit_type_"; @@ ( -visit_start_struct(V, OBJ, ARG1, NAME, ARG2, ERR) +visit_start_struct(V, NAME, OBJ, ARG1, ARG2, ERR) | -visit_optional(V, ARG1, NAME) +visit_optional(V, NAME, ARG1) | -visit_get_next_type(V, OBJ, ARG1, NAME, ERR) +visit_get_next_type(V, NAME, OBJ, ARG1, ERR) | -visit_type_enum(V, OBJ, ARG1, ARG2, NAME, ERR) +visit_type_enum(V, NAME, OBJ, ARG1, ARG2, ERR) | -VISIT_TYPE(V, OBJ, NAME, ERR) +VISIT_TYPE(V, NAME, OBJ, ERR) ) Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <1454075341-13658-19-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>
2016-02-08vl: Ensure qapi visitor properly ends struct visitEric Blake
Guarantee that visit_end_struct() is called if visit_start_struct() succeeded. This matches the behavior of most other uses of visitors, and is a step towards the possibility of a future patch that adds and enforces some tighter semantics to the visitor interface (namely, cleanup of the visitor would no longer have to mop up as many leftovers from an aborted partial visit). The change to code here matches the flow of hmp.c:hmp_object_add(); a later patch will then further simplify the cleanup logic of both places by refactoring visit_end_struct() to not require a second local error object.

2016-02-08hmp: Drop pointless allocation during qapi visitEric Blake
The qapi visitor contract allows us to visit a virtual structure, where we don't have any corresponding qapi struct. Most such uses pass NULL for @obj; but these two callers were passing a dummy pointer, which then gets allocated to heap memory but then immediately freed without use. Clean this up to suppress unwanted allocation, like we do elsewhere.

2016-01-18qom: Change object property iterator API contractDaniel P. Berrange
Currently the ObjectProperty iterator API works as follows: ObjectPropertyIterator *iter; iter = object_property_iter_init(obj); while ((prop = object_property_iter_next(iter))) { ... } object_property_iter_free(iter); This has the benefit that the ObjectPropertyIterator struct can be opaque, but has the downside that callers need to explicitly call a free function. It is also not in keeping with iterator style used elsewhere in QEMU/GLib2.

2015-11-06replay: command line optionsPavel Dovgalyuk
This patch introduces command line options for enabling recording or replaying virtual machine behavior. These options are added to icount command line parameter. They include 'rr' which switches between record and replay and 'rrfile' for specifying the filename for replay log.

This makes the purpose of the function clearer: it is not about the version of QEMU that's running, but the version string exposed in the emulated hardware.

Straightforward replacement, except for qemu_kill_report(), which printed a common part of its error message first, then the applicable special part. Print each complete message with a single error_report() instead. Multi-line messages were replaced by error_report() followed by error_printf(). The following changes were made to the error messages: * The "invalid date format" message was reworded to better fit the new error_report()+error_printf() pattern. * On the remaining messages, only the trailing newlines, "qemu:" and "error:" message prefixes were removed.

2015-10-12netfilter: add a netbuffer filterYang Hongyang
This filter is to buffer/release packets. Can be used when using MicroCheckpointing or other Remus like VM FT solutions. You can also use it to crudely simulate network delay. Doesn't actually delay individual packets, but batches them together, which is a delay of sorts. Usage: -netdev tap,id=bn0 -object filter-buffer,id=f0,netdev=bn0,queue=rx,interval=1000 NOTE: Interval is in microseconds, it can't be omitted currently, and can't be 0.
