How to trace down a memory leak in APE with valgrind

Given:

You already have a working/compiled APE server running and you still have the sources.

Rebuild (don’t use build.sh) with the following steps

Enter your APE source code directory and then do

cd deps/js/src/
./configure --enable-debug --enable-valgrind
make
cd ../../../
make

Now copy your rebuilt libape and aped to it’s default locations (see https://www.xosofox.de/2010/11/get-your-ape-up-to-date/)

Now run your ape with valgrind as a wrapper (I prefer to cd to /etc/ape so I don’t have to specify the ape.conf)

valgrind --leak-check=full --log-file=/path/to/mem.log /usr/bin/aped

pkill aped

All leaks will be written to the log and can be analyzed

Note: valgrind is slowing down the application dramatically in terms of CPU
