Any programmer accustomed to writing programs on Linux or System
|
||
|
|
V-type Unixes will have encountered the program variously known as
|
||
|
|
strace or truss, which monitors another program and produces a
|
||
|
|
detailed log of every system call the program makes - in other
|
||
|
|
words, all the program's interactions with the OS kernel. This is
|
||
|
|
often an invaluable debugging tool, and almost as good an educational
|
||
|
|
one.
|
||
|
|
|
||
|
|
When it's a GUI program (or rather, the GUI-related behaviour of
|
||
|
|
a program) that you want to understand or debug, though, the level
|
||
|
|
of interaction with the OS kernel is rarely the most useful one.
|
||
|
|
More helpfully, one would like to log all the program's interactions
|
||
|
|
with the X server in the same way.
|
||
|
|
|
||
|
|
This package provides xtruss, an X protocol loggers. It has a
|
||
|
|
command-line syntax similar to strace in its default mode, you just
|
||
|
|
prefix "xtruss" to the same command line you would have run anyway
|
||
|
|
and its output format is also more like strace, putting requests
|
||
|
|
and responses on the same line of output where reasonably possible.
