* g_thread_init users: don't call it if glib >= 2.31Alon Levy2011-12-201-0/+5
| | | | | | | | | | | | | | | | | | | | | | since commit f9b29ca03 included in release 2.31 (docs below say 2.32 but that is not correct) and onwards g_thread_init is deprecated and calling it is not required: http://developer.gnome.org/glib/unstable/glib-Deprecated-Thread-APIs.html#g-thread-init g_thread_init has been deprecated since version 2.32 and should not be used in newly-written code. This function is no longer necessary. The GLib threading system is automatically initialized at the start of your program. Fixes bulid failure when warnings are treated as errors on fedora 17. I only tested the change to vl.c, and copy pasted to the two other locations (couldn't decide if a wrapper for calling g_thread_init is uglier).

* trace: Add wildcard trace event supportMark Wu2011-11-012-3/+33
| | | | | | | | | | | A basic wildcard matching is supported in both the monitor command "trace-event" and the events list file. That means you can enable/disable the events having a common prefix in a batch. For example, virtio-blk trace events could be enabled using: trace-event virtio_blk_* on Signed-off-by: Mark Wu <wudxw@linux.vnet.ibm.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
* trace: use binary file open mode in simpletraceStefan Hajnoczi2011-09-211-1/+1
| | | | | | | | For Windows portability the simple trace backend must use the 'b' file open mode. This prevents the stdio library from mangling 0x0a/0x0d newline characters. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
* trace: portable simple trace backend using glibStefan Hajnoczi2011-09-211-26/+48
| | | | | | | | | Convert the simple trace backend to glib so that it works under Windows. We cannot use pthread directly but glib provides portable abstractions. Also use glib atomics instead of newish gcc builtins which may not be supported on Windows toolchains. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
* trace: [stderr] add support for dynamically enabling/disabling eventsLluís2011-09-012-0/+48
| | | | | | | | Uses the generic interface provided in "trace/control.h" in order to provide a programmatic interface as well as command line and monitor controls. Signed-off-by: Fabien Chouteau <chouteau@adacore.com> Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
* trace: add "-trace events" argument to control initial stateLluís2011-09-014-5/+61
| | | | | | | | | | | The "-trace events" argument can be used to provide a file with a list of trace event names that will be enabled prior to starting execution, thus providing early tracing. This saves the user from manually toggling event states through the monitor interface or whichever backend-specific interface. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
* trace: separate trace event control and query routines from the simple backendLluís2011-09-014-11/+33
| | | | | | | | Generalize the 'st_print_trace_events' and 'st_change_trace_event_state' into backend-specific 'trace_print_events' and 'trace_event_set_state' (respectively) in the "trace/control.h" file. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
* trace: avoid conditional code compilation during option parsingLluís2011-09-014-12/+51
| | | | | | | | A default implementation for backend-specific routines is provided in "trace/default.c", which backends can override by setting "trace_default=no" in "configure". Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
