    public function mergeTo($history)

        $this->setHistory($history);
        $this->mergeGitLog();
    }

    public function mergeGitLog()
    {
        $log = $this->fetchGitLog();

The method fetchGitLog() does not seem to exist on object<hiqdev\chkipper\history\GitLogParser>.

        var_dump($log);

var_dump($log); looks like debug code. Are you sure you do not want to remove it? This might expose sensitive data.

        die();

The method mergeGitLog() contains an exit expression.

        foreach ($log as $hash => $data) {

foreach ($log as $hash => $data) { $this->getHistory()->addCommit($data['tag'], null, $data['commit'], true); } does not seem to be reachable.

            $this->getHistory()->addCommit($data['tag'], null, $data['commit'], true);

The method addCommit() does not exist on hiqdev\chkipper\history\History. Did you maybe mean addCommitLinks()?

        }
    }

    public function parseGitLog()
    {
        exec("git log --date=short --pretty='format:%h %ad %s [%ae] %d'", $logs);

        return $this->parseLines($logs);

It seems like $logs can also be of type null; however, hiqdev\chkipper\history\GitLogParser::parseLines() does only seem to accept array, maybe add an additional type check?

    }

    public function parseLines(array $lines)
    {
        $this->getHistory()->initTags();

        foreach ($lines as $line) {
            if (!preg_match('/^(\w+) (([0-9-]+) (.*?) \[.*?\]) *\(?(.*?)\)?$/', $line, $m)) {
                throw new UnexpectedValueException('failed parse git line');
            }
            $tag  = $this->matchTag($m[5]);
            $note = $this->matchNote($m[4]);
            if ($tag) {

The expression $tag of type string|null is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.

                $this->addTag($tag, $m[3]);
            }
            if (false && $note) { /// disabled adding notes
                $this->addNote($note);
            }
            $this->addCommit($m[1], $m[2]);
        }

        return $this->getHistory();
