Can TPTP do this? [message #134344]

Hi All,

I am new to TPTP (referred by google :>). I wonder if TPTP can help me to
the following.

I have a C++ application which I would like to profile by just inserting
logs or traces. I want to record the execution call graph and the time it
take to run each function. xml file will be generated

I want to visualize this in TPTP. Call graph with hotspot, table of
functions sorted by time taken, filtering etc.

I am thinking about writing some extender of TPTP to read in the xml file
I created and somehow talk to the TPTP framework to tell it about the
execution and timing data.

Am I on the right track? Can TPTP do this?

Thanks!

Hi Eric,

Instead of extender to read in the xml file, you can log the information in
the XML4Trace format
( http://www.eclipse.org/tptp/platform/documents/resources/pro filingspec/XML4Profiling.htm)
which can then be imported as regular profile file to TPTP and be visualized
in TPTP tables and graphs.

To generate an example of profiling file, you can profile a Java application
with TPTP 4.4.1 and specify to send profile data to a file (under the
monitor tab of the profiling configuration). It's a zipped text file and you
can unzip it to inspect its content.

Thanks, I think XML4Trace will work for me.

Is there a C++ library/API which I can use to generate this format?

Thanks!

I tried Eugene's suggestion and profiled a sample java application. I got
a trcxml file and uncompress it and it has several .bin files (I assume
one .bin files represent one trace). However, I cannot uncompress the .bin
file.

Can you shed some light on how can I create my trcxml file with multiple
trace using C++ or perl (basically ASII). Thanks!

Eric,

The bin file is in compressed XML format (it's called binary file). You
can find the definition by check the below link:
https://bugs.eclipse.org/bugs/attachment.cgi?id=89144
https://bugs.eclipse.org/bugs/attachment.cgi?id=93126

These two links are the attachments of Bugzilla 196713, you can also check
the discussion on compressed file format by checking link:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=196713

Hope it helps.

Thanks.

Hi Eric,

The source code for emitting trace XML fragments is in
org.eclipse.tptp.platform.jvmti.runtime/sec-native/src/JPIAg ent/PrintXML.cpp
(and PrintXML.h). It was not designed to be fully reuse butt take a look for
information on how to generate the events there.
