Hi All, I''ve got a problem when I have USDT probes in a static library and in the application code outside of the library. I build the static library containing some USDT probes, glomming everything together (ld -r) before creating the .a file to preserve the probe symbols. This all works fine. I build an application which also has some USDT probes. When I build the application which

Hi, As I''ve discussed before whenever we add USDT probes to a C++ function and call dtrace -l we get the mangled C++ name for the dtrace function, being listed :( Now the point of USDT probes is to abstract a higher level semantic construct for users to make use of. Surely it is not meant to be listing Unstable Interfaces (implementation details), such as the containing C++

Hi, Is there a specific reason the DTRACEHIOC_REMOVE ioctl is deprecated? I found I needed to use it in my Perl USDT provider code[*], which creates providers dynamically at runtime. I wonder if I''m missing a better way of doing the same thing. The situation I''m handling with the remove operation is killing and recreating a perl interpreter in the same process, which

Hi, I''m posting a question hoping someone will know the answer off hand thereby reducing my search time. :-) With USDT probes, the tracepoint is only installed by libdtrace itself, never by the drti ioctl. So whenever I run a program with an USDT probe, no tracepoint is installed. Only after I run the dtrace command the tracepoint is actually installed on the victim process. My question

Hi people, When working with some usdt C++ probes we have come across a few issues. Controlling USDT Function name: Putting in usdt probes into C++ code gives you the mangled enclosing function name for the probes Function name. Working around this can be a pain. You need to wrap your usdt probes in extern C functions and call these. Could we have an option to control the Function name for

I have a long equation that I need to break in the R documentation of a package or it trails off the right hand side of the page. Here's the formula: \deqn{Cov(r_{ist}, r_{iuv})= [.5\rho_{ist}\rho_{iuv}(\rho_{isu}^2 + \rho_{isv}^2 + \rho_{itu}^2 + \rho_{itv}^2) + \rho_{isu}\rho_{itv}+ \rho_{isv}\rho_{itu}-(\rho_{ist}\rho_{isu}\rho_{isv} + \rho_{its}\rho_{itu}\rho_{itv}) +

Suppose I have a USDT probe in Firefox and that I''m trying to catch the startup with a probe like this: proc:::exec-success /execname == "firefox-bin"/ { start = timestamp; } and stop tracing when Firefox hits this USDT probe: mozilla:::main-entry { exit(0); } How do I put the running firefox-bin into "trace mode" so that my USDT probe fires? Thanks, Joel

Some targets don't have the problem because they prefix all names with an undercore. Apart from that I am not aware of any solution to the problem of keywords clashing with variable names in intel syntax. - Matthias > On Jul 23, 2015, at 9:18 AM, Reid Kleckner <rnk at google.com> wrote: > > So, there is no prior art for escaping the name of a global symbol with the same name

Hello, I am trying to get documentation how how this lazyloading happens when you are dealing with dtrace probes being added to user applications. In particular if it somehow avoids the overhead of registering dtrace probes when they aren''t needed, how does it know if they are needed, etc... thanks, Robert

Hola. Sospecho que el problema puede estar relacionado con la versión del paquete que estás instalando (según veo, la última) y la versión de R que tienes instalada (2.15). Quizás conociendo la variante de linux que estás utilizando alguien de la lista te pueda orientar mejor conociendo las particularidades de *ese* linux.

So, there is no prior art for escaping the name of a global symbol with the same name as a register? If there is, I'd rather we just implement it and leave it at that. We can probably fix the 'flags' case easily in LLVM, but I'd rather not bend over backwards to make ZMM0 be a global name when AVX is disabled.

Hello, If I release a new kernel module, do I need to release a SDT provider with it? Just like what "mdb" does - a mdb module together with the associated kernel module. Is it a "MUST" or a "OPTION"? Also what''s the requirement of USDT and user application? Is it encouraged or not to have many probes inside the code? Can I define my own
