Hello folks,
we run a database on valgrind and tests on that database, to find memory leaks.
The tests are written in Python, the database is written in C++. A test
contains many testcases and configurations, so that a test may run more than 12
hours and has all in all (with all combinations of testcases and
configurations) more than 10000 testruns (i.e. a testrun is a combination of a
testcase with a configuration). If a memory leak was detected, it was helpful,
to know, to which testrun this leak belongs.
The testrun-name itself is not printed out in the stack (because the stack only
contains the C++-stack - of course - and the testrun-name is visible in Python,
only), therefore, we need to map the time, when the test was started and the
time, when the memory leak occurred. We use the time-stamp parameter, to detect
the latter. The timestamp printed out by valgrind is now not the timestamp of
allocation, but of printing the result. Since memory leaks can only be detected
at the end of a program, these are printed out at the end of the program, so
that a match between testrun and memory leak is impossible. Now I would like to
modify the sources of valgrind, so that the time of allocation is also stored
internally and printed out in the summary.
Could you please kindly give me a hint, which structure was to change and where
there timestamp then needs to be inserted?
I am fine with the relative time-stamp; I do not need an absolute one!
Kind regards and thank you,
Robin Rehrmann
