Note this code is pre-beta.

It is definitely not ready yet for production.

stellar-core

Stellar-core is a C++ implementation of the Stellar Consensus Protocol that maintains a local copy of the ledger and syncs with other instances of stellar-core on the network. Learn more by reading the overview document.

Documentation

Documentation of the code's layout and abstractions, as well as for the functionality available, can be found in ./docs.

Contributing

We're striving to keep master's history with minimal merge bubbles. To achieve this, we're asking PRs to be submitted rebased on top of master.

To keep your local repository in a "rebased" state, simply run:

git config --global branch.autosetuprebase always changes the default for all future branches

git config --global branch.master.rebase true changes the setting for branch master

note: you may still have to run manual "rebase" commands on your branches to rebase on top of master as you pull changes from upstream.

Code formatting wise, we have a .clang-format config file that you should use on modified files.

Running tests

run tests with: src/stellar-core --test

run one test with: src/stellar-core --test testName

run one test category with: src/stellar-core --test '[categoryName]'

Categories (or tags) can be combined: AND-ed (by juxtaposition) or OR-ed (by comma-listing).

Tests tagged as [.] or [hide] are not part of the default test test.

Running tests against postgreSQL

There are two options. The easiest is to have the test suite just create a temporary postgreSQL database cluster in /tmp and delete it after the test. That will happen by default if you run make check.

You can also create a temporary database cluster manually, by running ./src/test/selftest-pg bash to get a shell, then running tests manually. The advantage of this is that you can examine the database log in $PGDATA/pg_log/ after running tests, as well as manually inspect the database with psql.

Finally, you can use an existing database cluster so long as it has databases named test0, test1, ..., test8, and test. Do set this up, make sure your PGHOST and PGUSER environment variables are appropriately set, then run the following from bash:

for i in $(seq 0 8) ''; do
    psql -c "create database test$i;"
done

Running stress tests

We adopt the convention of tagging a stress-test for subsystem foo as [foo-stress][stress][hide].

Then, running

• stellar-core --test [stress] will run all the stress tests,
• stellar-core --test [foo-stress] will run the stress tests for subsystem foo alone, and
• neither stellar-core --test nor stellar-core --test [foo] will run stress tests.
