This server dump the symbols for your native libraries, you can read here how google breakpad works.
Just send a ziped folder(you can include multiple ABIs - server look recursively for .so files) with .so files or a single .so file as form data and receive back a .zip archive with symbols.
> curl --form [email protected] http://localhost:8003/dump_syms -o symbols.zip
> unzip -l symbols.zip

Decoding Crash Dumps minidump_stackwalk
Server decodes crash with .dmp and symbols.zip files. You just send this files and receive decoded crash 🤗

dump_syms works only on Linux 😐, so you can easily run ./build_and_run_docker.sh script which builds & runs docker with a server, take a look at Docker section.
- Google breakpad(
dump_syms) - Python2
Note: google breakpad dump_syms works only on Linux
This repo contains Dockerfile inside docker folder, so you need just run ./build_and_run_docker.sh script which builds a container && start the container with server on port 4000
