New submission from Roman Podoliaka:
There are a couple of errors in SystemTap examples from "Instrumenting CPython
with DTrace and SystemTap" page
(https://docs.python.org/dev/howto/instrumentation.html):
1) in SystemTap double quotes are used to denote string literals. As is
examples fail with:
parse error: expected literal string or number
saw: operator ''' at show_call.stp:1:15
source: probe process('python').mark("function__entry") {
2) stap -c option expects a command as a single string argument, not as a list
of strings. As is the following example:
$ stap \
show-call-hierarchy.stp \
-c ./python test.py
will not run a test.py script, but instead ./python without any args, thus it
will print a
prompt (i.e. >>>) and wait for user input.
