Bug ID: 471936
Summary: Do not generate (or more likely unlink) log files
associated with --trace-children-skip
Classification: Developer tools
Product: valgrind
Version: 3.22 GIT
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: memcheck
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Consider this small example:
/* system.c */
#include <stdlib.h>
int main(void)
{
system("ls");
}
If I run this under memcheck with
valgrind --trace-children=yes --log-file=mc.%p.log ./system
Then I get two files, one for 'system' and one for 'ls'
If I add --trace-children-skip=*/ls then I still get two files.
Now the second one is that created after the fork() done by system() so it is
also for 'system', but since we're not tracing children Valgrind directly calls
'execve()' causing the file to be truncated (when we do trace children this
stub would be overwritten by the log file for "ls").
I find these files pretty useless and annoying. It would be nice to find a way
to remove them.
