RunningVoltDb with valgrind

[mike alexeev]

Hi All, are there any tricks to run VoltDB server process with valgrind? If I simply try

valgrind --leak-check=full --show-reachable=yes --error-exitcode=-1 /usr/bin/java .....(voltdb options)

 

all I see is a single java processes running, no valgrind. There is an output from the valgrind at the very beggining but then it looks like the java process gets forked and valgrind quits.

 

Thanks,

MIke

Hi Mike,

We run the following to get a valgrind build and a set of tests running:

ant -Dbuild=memcheck -DVOLT_REGRESSIONS=local -DtimeoutLength=2700000 clean compile voltdbipc eecheck junit

Thanks Ruth. I found that you need to add '--trace-children=yes' to the valgrind options. Than you can run it from the command line

Valgrind didn't (used to?) play well with the JVM; the JVM does weird,
horrible and interesting code rewriting that valgrind finds
suspicious.

Would be interesting to know if valgrind's gotten better with JIT'd
code, though.

(So our valgrind command that Ruth sent starts the EE as a separate C
process and only runs valgrind against that - instead of JNI, we do
IPC to the EE in this case).

Indeed, valgrind is not happy with Java, at least not on Ubuntu 12.04
