Empirically, the user can specify that he wants to see every debugging message
-of GRAS while only being interested into the messages at level "error" or
+of MSG while only being interested into the messages at level "error" or
higher about the XBT internals.
\subsection log_app 1.3 Message appenders
Here is an example of the most basic type of macro. This is a logging
request with priority <i>warning</i>.
-<code>XBT_CLOG(MyCat, gras_log_priority_warning, "Values are: %d and '%s'", 5,
+<code>XBT_CLOG(MyCat, xbt_log_priority_warning, "Values are: %d and '%s'", 5,
"oops");</code>
A logging request is said to be enabled if its priority is higher than or
XBT_LOG_NEW_DEFAULT_SUBCATEGORY(SA, VSS);
int main() {
- / * Now set the parent's priority. (the string would typcially be a runtime option) * /
+ / * Now set the parent's priority. (the string would typically be a runtime option) * /
xbt_log_control_set("SA.thresh:3");
/ * This request is enabled, because WARNING >= INFO. * /
}

\section log_user 3. User interface
\section log_use_conf 3.1 Configuration
Although rarely done, it is possible to configure the logs during
program initialization by invoking the xbt_log_control_set() method
manually. A more conventional way is to use the --log command line
-argument. xbt_init() (called by MSG_init(), gras_init() and friends)
+argument. xbt_init() (called by MSG_init() and friends)
checks and deals properly with such arguments.
-The following command line arguments exist, but are deprecated and
-may disappear in the future: --xbt-log, --gras-log, --msg-log and
---surf-log.

\subsection log_use_conf_thres 3.1.1 Threshold configuration
The most common setting is to control which logging event will get
displayed by setting a threshold to each category through the
-<tt>thres</tt> keyword.
+<tt>threshold</tt> keyword.
-For example, \verbatim --log=root.thres:debug\endverbatim will make
+For example, \verbatim --log=root.threshold:debug\endverbatim will make
SimGrid <b>extremely</b> verbose while \verbatim
--log=root.thres:critical\endverbatim should shut it almost
-completely off. The full list of recognized thresholds is the following:
+completely off.
+
+Note that the <tt>threshold</tt> keyword can be abbreviated here. For example,
+all the following notations have the same result.
+\verbatim
+--log=root.threshold:debug
+--log=root.threshol:debug
+--log=root.thresho:debug
+--log=root.thresh:debug
+--log=root.thres:debug
+--log=root.thre:debug
+--log=root.thr:debug
+--log=root.th:debug
+--log=root.t:debug
+--log=root.:debug <--- That's obviously really ugly, but it actually works.
+\endverbatim
+
+The full list of recognized thresholds is the following:
- trace: enter and return of some functions
- debug: crufty output
- %%p: Priority name (LOG4J compatible)
- %%h: Hostname (SimGrid extension)
- - %%P: Process name (SimGrid extension)
+ - %%P: Process name (SimGrid extension -- note that with SMPI this is the integer value of the process rank)
- %%t: Thread "name" (LOG4J compatible -- actually the address of the thread in memory)
- %%i: Process PID (SimGrid extension -- this is a 'i' as in 'i'dea)
There is also compile time constant, \ref XBT_LOG_STATIC_THRESHOLD, which
causes all logging requests with a lower priority to be optimized to 0 cost
-by the compiler. By setting it to gras_log_priority_infinite, all logging
+by the compiler. By setting it to xbt_log_priority_infinite, all logging
requests are statically disabled at compile time and cost nothing. Released executables
<i>might</i> be compiled with (note that it will prevent users to debug their problems)
-\verbatim-DXBT_LOG_STATIC_THRESHOLD=gras_log_priority_infinite\endverbatim
+\verbatim-DXBT_LOG_STATIC_THRESHOLD=xbt_log_priority_infinite\endverbatim
Compiling with the \verbatim-DNLOG\endverbatim option disables all logging
requests at compilation time while the \verbatim-DNDEBUG\endverbatim disables
