tools lib traceevent: Use proper function parameter type

2012-05-24T14:34:12Z

The param needs to be updated when setting args up so that the loop in process_defined_func() can see the correct param->type for the farg.

tools lib traceevent: Fix freeing arg on process_dynamic_array()

2012-05-24T14:33:53Z

The @arg paremeter should not be freed inside of process_XXX(), because it'd be freed from the caller of process_arg(). We can free it only after it was reused for local usage.

tools lib traceevent: Fix a possibly wrong memory dereference

2012-05-24T14:33:34Z

If set_op_prio() failed, the token will be freed at out_free, then arg->op.op would turn out to be a dangle pointer. After returning EVENT_ERROR from process_op(), free_arg() will be called and then it will finally see the dangling pointer.

tools lib traceevent: Fix a possible memory leak

2012-05-24T14:32:10Z

If event_read_fields failed in the middle, each member of struct format_field should be freed also.

tools lib traceevent: Allow expressions in __print_symbolic() fields

2012-05-24T14:29:25Z

The __print_symbolic() function takes a sequence of key-value pairs for pretty-printing a constant. The new kvm:kvm_exit print fmt uses the expression: __print_symbolic(..., { 0x040 + 1, "DB excp" }, ...) Currently only atoms are supported and this print fmt fails to parse. This patch adds support for expressions instead of just atoms so that 0x040 + 1 is parsed successfully.

parse-events: Rename struct record to struct pevent_record

2012-04-25T11:35:48Z

As libtraceevent will be a library, having struct record is far too generic of a name to use. Renaming it to be consistent with the rest of the functions will be a better long term solution.

parse-events: Support '+' opcode in print format

2012-04-25T11:35:38Z

The '+' opcode is not supported in the arguments for the print format. This patch adds support for it.

parse-events: Let pevent_free() take a NULL pointer

2012-04-25T11:35:35Z

The pevent_free() should ack like other free()s and allow a NULL pointer to be passed to it which makes error handling a bit easier for the users of pevent_free().
