When we are valgrinding we don't really care about the child processes, which might be qemu, libvirtd, etc. So disable tracing into children (at least, as far as is possible with valgrind, which is not entirely disabling it, but suppressing it). --- m4/guestfs_progs.m4 | 2 +- 1 file changed, 1 insertion(+), 1 delet...

I am trying to do a classic R -d valgrind --vanilla < mypkg-Ex.R as described in http://cs.swan.ac.uk/~csoliver/ok-sat-library/internet_html/doc/doc/R/2.9.1/doc/manual/R-exts.html#Using-valgrind The problem is valgrind crashes imediately. I am using Ubuntu 10.04 LST (actually Biolinux) on a 64bit Dell Precision laptop with 4 core-i5 Intel processors. I have R-2-15-0 installed from source

When valgrinding plugins, the following sequence can happen: plugin_free -> dlclose -> unloads the plugin and symbol table exit -> valgrind prints failures (the same applies to filters). When valgrind is printing the failures, it looks up the addresses in the symbol table, but that has be...

From: "Richard W.M. Jones" <rjones at redhat.com> This commit allows you to run the daemon under valgrind. You have to enable it at configure time: ./configure --enable-valgrind-daemon This should *not* be done for production builds. When this feature is enabled, valgrind is added to the appliance and the daemon is run under valgrind. Log messages from valgrind are passed

Hi, I've seen on the LLVM's Open Projet Page [1] an idea about using LLVM to generate native code in Valgrind. For what I know, Valgrind uses libVEX to translate native instructions into a bitcode, used to add the instrumentation and then translated back to native code for execution. Valgrind and LLVM are two tools that I use nearly every day. I'm also very interested in code

R CMD check --use-valgrind <packagename> used to run valgrind on the tests in the tests directory of the package. But it seems to have stopped. R-2.9.1 doesn't -- at least on my box -- and neither does R-2.10.0 (devel). I am not sure when this stopped. I think 2.8.x did this. The only old R I have around is 2.6.0 and it certainly does. R CMD check --help for 2.9.1 says (among other

...eing applied to nbdkit when run by many of the tests (patches 1-2). Unfortunately I'm not able to make it actually fail tests when valgrind fails. Although the situation is marginally improved in that you can now manually examine the *.log files and find valgrind failures that way. Also adds valgrinding of the Python plugin (patch 3). Along the way I found that when we create a TLS session object we never free it, which is a bit of a problem (although easy to fix - patch 4). I'll need to backport this fix to every stable branch. It's not clear how exploitable this is -- it's my feel...

Instead of forcing valgrind to be run when --enable-valgrind-daemon is passed to configure, enable it only when the backend setting "valgrind_daemon" is set. This allows developers to keep building with --enable-valgrind-daemon, which unconditionally adds valgrind in the appliance but using only when requested. When --enable-valgrind-daemon is not passed (typical for release builds),

By default valgrind suppresses many leaks. I'm not even sure exactly how it decides which ones to suppress, but certainly global variables pointing to malloc’d data are suppressed, which is not useful behaviour. Tell valgrind to show all leaks. It won't give an error on them. However to do this we also need a much more comprehensive list of suppressions so that we don't constantly

Dear all, I'm trying to debug my R package with valgrind, but I cannot get past the point where I load make the data, as valgrind crashes when trying to extract a single time series object of a multivariate mts object. I'm using R 2.15.0 with platform x86_64-redhat-linux-gnu (64-bit). The valgrind.R contains code data(Seatbelts) y<-Seatbelts[,"VanKilled"] And I run

Hi, I am trying to integrate valgrind with sftp-server. I've replaced the sftp subsystem line in /etc/ssh/sshd_config file as follows: Subsystem sftp /usr/bin/valgrind --log-file=~/abc --trace-children=yes /root/openssh-6.2p2/sftp-server But I am not able to connect to the sftp-server. These are the last messages that the client logs. <snip> debug1: Sending subsystem: sftp

Hi, Just a thought... How are you going to port llvm so it doesn't use libc? Valgrind uses the same resources as the running program, so it can't use the system libc's malloc nor any other functions so it doesn't get "confused". Regards and let's hope this project is accepted :-) F Owen Anderson wrote: > Rodrigo, > > On Mar 20, 2009, at 8:41 AM,

I had to add several suppressions because Python leaks memory by design, and also increase the max depth of valgrind stack traces because Python stack traces are very deep. Note that to do proper valgrinding of Python itself we would need to specially recompile Python: https://svn.python.org/projects/python/trunk/Misc/README.valgrind --- tests/test-lang-plugins.c | 3 +- valgrind/python.suppressions | 75 ++++++++++++++++++++++++++++++++++++ wrapper.c | 2 +- 3 files changed, 7...
