2016-07-18trace: Conditionally trace events based on their per-vCPU stateLluís Vilanova
Events with the 'vcpu' property are conditionally emitted according to their per-vCPU state. Other events are emitted normally based on their global tracing state. Note that the per-vCPU condition check applies to all tracing backends.

2014-05-07trace: [tracetool] Minimize the amount of per-backend codeLluís Vilanova
Backends now only contain the essential backend-specific code, and most of the work is moved to frontend code. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

Public backends are those printed by "--list-backends" and thus considered valid by the configure script. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2012-11-16Avoid all systemtap reserved wordsDaniel P. Berrange
Over time various systemtap reserved words have been blacklisted in the trace backend generator. The list is not complete though, so there is continued risk of problems in the future. Preempt such problems by specifying the full list of systemtap keywords listed in its parser as identified here: http://sourceware.org/ml/systemtap/2012-q4/msg00157.html Signed-off-by: Daniel P.

2012-04-18tracetool: handle DTrace keywords 'in', 'next', 'self'Stefan Hajnoczi
Language keywords cannot be used as argument names. The DTrace backend appends an underscore to the argument name in order to make the argument name legal. This patch adds 'in', 'next', and 'self' keywords to dtrace.py. Also drop the unnecessary argument name lstrip() call. The Arguments.build() method already ensures there is no space around argument names. Furthermore it is misleading to do the lstrip() *after* checking against keywords because the keyword check would not match if spaces were in the name.
