From f003ec714195caa5b49be66526d2645e42ee86b0 Mon Sep 17 00:00:00 2001 From: clawbot Date: Tue, 17 Mar 2026 12:48:52 +0100 Subject: [PATCH] fix: use absolute path for dev DATA_DIR default, clarify env docs (#46) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes #45. ## Problem 1. The README didn't clearly explain what `WEBHOOKER_ENVIRONMENT=dev` vs `prod` actually changes. 2. The dev-mode default for `DATA_DIR` was `./data` — a relative path whose meaning depends on the working directory. There's no reason to use a relative path even in development. ## Changes ### Code (`internal/config/config.go`) - Replace the dev default `DATA_DIR` from `./data` to `$XDG_DATA_HOME/webhooker` (falling back to `$HOME/.local/share/webhooker`). This follows the XDG Base Directory Specification and ensures the data directory is always an absolute path regardless of the working directory. - Add `devDataDir()` helper that resolves the XDG path, with a `/tmp/webhooker` last-resort fallback if `$HOME` can't be determined. ### Tests (`internal/config/config_test.go`) - `TestDevDataDir`: verifies XDG_DATA_HOME is respected, HOME fallback works, and the result is always absolute. - `TestDevDefaultDataDirIsAbsolute`: integration test that creates a full Config via fx and asserts the dev default DataDir is absolute. ### README - Add a table documenting exactly what `dev` vs `prod` changes: DATA_DIR default, CORS policy, and session cookie Secure flag. - Clarify that log format and security headers are independent of the environment setting. - Update the DATA_DIR default in the configuration variable table.
