Dado que las variables de entorno pueden configurarse fuera del código, pero pueden ser leídas por el código, y no tienen que ser almacenadas (committed en `git`) con el resto de los archivos, es común usarlas para configuraciones o **ajustes**.

                if (Files.exists(refFile)) {
                    revision = readFirstLine(refFile);
                } else if (Files.exists(gitDir.resolve("packed-refs"))) {
                    // Check packed references for commit ID
                    Pattern p = Pattern.compile("^([a-f0-9]{40}) " + refName + "$");
                    try (Stream<String> lines = Files.lines(gitDir.resolve("packed-refs"))) {

            return 100L;
        }

        @Override
        public long getDocumentSize() {
            return 10L;
        }

        @Override
        public void commit() {
            /* No-op */ }

        @Override
        public void store(DataStoreParams params, java.util.Map<String, Object> data) {
            /* No-op */ }
    }

* After applying the PR, the new tests should pass.
* Coverage should stay at 100%.
* If you see the PR makes sense, or we discussed it and considered it should be accepted, you can add commits on top of the PR to tweak it, to add docs, tests, format, refactor, remove extra files, etc.
* Feel free to comment in the PR to ask for more information, to suggest changes, etc.

Ortam değişkenleri kodun dışında ayarlanabildiği, ama kod tarafından okunabildiği ve dosyalarla birlikte saklanmasının (ör. `git`’e commit edilmesinin) gerekmediği için, konfigürasyon veya **ayarlar** için sıkça kullanılır.
