 # Changelog
 
+## [0.3.0](https://github.com/sbrow/envr/compare/v0.2.1...v0.3.0) (2026-06-16)
+
+
+### ⚠ BREAKING CHANGES
+
+* The encryption format of databases has changed. Age encryption is no longer supported, and no automatic migration path was implemented.
+
+### Features
+
+* All encryption/decryption now happens in-memory. ([fe2b256](https://github.com/sbrow/envr/commit/fe2b256bd61eaf551d53faf3893b473a64a94667))
+* Config can be loaded from any path with `--config-file (-c)` flag. ([4a26ee8](https://github.com/sbrow/envr/commit/4a26ee814591e6aab0eb99d2359d51b31011edfe))
+* Switched from age to libsodium. ([23b8c2d](https://github.com/sbrow/envr/commit/23b8c2dc671a23cf76cf6746b33806ded9381486))
+
+
+### Performance Improvements
+
+* Improved writer performance. ([365e914](https://github.com/sbrow/envr/commit/365e9149b1a738ac9119bb5f74dc7e047ecfed5b))

+# Test Coverage Plan
+
+## Current State
+
+- 104 tests, all passing
+- Strong coverage: crypto, ssh, db CRUD + env_file + update_dir, config save/load + paths, scan, features, cant_scan, parse_args, `-c`/`--config-file` flag
+- Misleading test files: `cmd_check_test`, `cmd_list_test`, `cmd_nushell_completion_test` don't test their namesake procs
+- Biggest remaining gap: all `cmd_*` handlers untested
+
+## Command handler tests
+
+Stdout will be captured by redirecting `os.stdout` to a pipe.
+
+### `cmd_version` (cmd_version.odin)
+- Test default output (prints VERSION)
+
+### `cmd_list` (cmd_list.odin)
+- Test TTY path: fixture DB with rows, capture table output
+- Test non-TTY path: capture JSON output, unmarshal and verify keys/values
+- Test empty DB: verify clean output (empty table or `[]`)
+
+### `cmd_backup` (cmd_backup.odin)
+- Test successful backup: valid path, verify `db_insert` called
+- Test missing file: verify error message
+- Test duplicate backup: verify rejection or update behavior
+
+### `cmd_remove` (cmd_remove.odin)
+- Test successful removal: existing entry, verify `db_delete` called
+- Test removal of non-existent entry: verify error or no-op
+
+### `cmd_restore` (cmd_restore.odin)
+- Test successful restore: entry exists in DB, verify file written to correct path
+- Test restore of missing entry: verify error
+- Test directory creation: restore to path with missing parent dirs
+
+## Hard to test (interactive / external deps)
+
+### `cmd_deps` (cmd_deps.odin)
+- Needs `git` and/or `fd` in PATH
+- Test TTY and non-TTY paths
+- Skip if dependencies not available (with `#assert` like TODO 28 suggests)
+
+### `cmd_scan` (cmd_scan.odin)
+- Needs `fd` installed
+- Test with fixture git repo containing `.env` files
+- Test `find_unbacked` integration (already partially tested in `cmd_check_test.odin`)
+- Non-TTY JSON output path
+
+### `cmd_edit_config` (cmd_edit_config.odin)
+- Needs refactoring: extract `$EDITOR` parsing into testable helper (TODO 12)
+- Test multi-word editor values (`"code -w"`)
+- Test missing `$EDITOR`
+
+### `cmd_init` (cmd_init.odin)
+- Interactive prompt makes this hard
+- Needs refactoring: extract SSH key discovery and config generation into testable procs
+- Test `--force` flag behavior
+
+### `prompt.odin`
+- Needs refactoring to be testable
+- `render_options` could be tested if it accepted an `io.Writer`
+- `read_key` could be tested with a pipe/redirect instead of raw stdin
+- `multi_select` is end-to-end interactive, likely integration test only
+
+## Notes
+
+- DB integration tests should use in-memory SQLite (`:memory:`) where possible.
+- Temp dir fixtures should follow the pattern in `scan_test.odin`.
+- External dependency tests (`fd`, `git`) should use `#assert` to ensure the dependency is present rather than silently skipping (TODO 28).
+- Tests that manipulate the `HOME` env var must use a mutex to prevent races with parallel test execution.

-# TODO
+# TODOs
 
-Note: These todos can wait until all the subcommands have been ported.
 
-## HIGH
+1. Consider giving db its own allocator
 
-2. **db.odin:380-383, 405, 446** — `sqlite.bind_text` return values overwritten but never checked. A failed bind means `sqlite.step` operates on unbound params.
+2. **db.odin:324-327** — Map iteration (`remote_set`) is non-deterministic. Same file can produce different JSON on each backup, causing spurious DB diffs. Sort remotes before storing.
 
-3. **config.odin:52-54** — `os.user_home_dir` error silently ignored. If it fails, `home` is `""` and all paths become relative (`".envr"` instead of `"~/.envr"`).
+3. **db.odin:135, 250** — String interpolation into SQL (`VACUUM INTO '%s'`, `ATTACH DATABASE '%s'`). Currently safe because input is controlled, but fragile.
 
-## MEDIUM
+4. **features.odin:30-41** — `find_binary` uses `strings.join` instead of `filepath.join`, uses `os.stat` instead of checking executability, hardcodes `:` as PATH separator (wrong on Windows).
 
-4. **db.odin:29-35** — `make_temp_path` never calls `strings.builder_destroy`. Leaks builder buffer every call.
+5. **cmd_restore.odin:20-30 & cmd_remove.odin:19-29** — Identical path-resolution block copy-pasted. `is_abs` guard is redundant since `filepath.abs` is a no-op on absolute paths. Extract a helper.
 
-5. **db.odin:324-327** — Map iteration (`remote_set`) is non-deterministic. Same file can produce different JSON on each backup, causing spurious DB diffs. Sort remotes before storing.
+6. **cmd_restore.odin:44** — `os.mkdir_all` error silently discarded. Subsequent write failure will be confusing.
 
-6. **db.odin:470-473** — `string_to_cstring` allocates via `strings.clone_to_cstring` and never frees. Called dozens of times across db operations.
+8. **config.odin:178** — `search_paths` silently ignores `os.user_home_dir` error. If home is empty, `~` isn't expanded. Same class of bug as issue 3.
 
-7. **db.odin:470, 462** — Both `string_to_cstring` and `cstring_to_string` ignore allocation errors. A nil cstring gets passed to SQLite (UB).
+10. **db.odin:115** — `json.unmarshal_string` error not checked. Malformed JSON silently produces empty/partial data.
 
-8. **db.odin:135, 250** — String interpolation into SQL (`VACUUM INTO '%s'`, `ATTACH DATABASE '%s'`). Currently safe because input is controlled, but fragile.
+11. **db.odin:352-353** — `hex.encode` error ignored. `string(hex_bytes)` aliases the byte slice.
 
-9. **features.odin:30-41** — `find_binary` uses `strings.join` instead of `filepath.join`, uses `os.stat` instead of checking executability, hardcodes `:` as PATH separator (wrong on Windows).
+12. **cmd_sync.odin:80, cmd_list.odin:33, cmd_deps.odin:9** — `make([]string, 2)` for table rows never freed. Leaks per row. Defer to memory pass.
 
-10. **cmd_restore.odin:20-30 & cmd_remove.odin:19-29** — Identical path-resolution block copy-pasted. `is_abs` guard is redundant since `filepath.abs` is a no-op on absolute paths. Extract a helper.
+13. **cmd_list.odin** — Non-TTY branch builds `ListEntry` structs and marshals JSON separately. Now that `render_json_rows` (issue 1) accepts an `io.Writer` and uses `json.marshal`, unify both branches to use it. Note: will change JSON keys from `"directory"/"path"` to `"Directory"/"Path"`.
 
-11. **cmd_restore.odin:44** — `os.mkdir_all` error silently discarded. Subsequent write failure will be confusing.
+14. Check for prealloc opportunities. i.e. `make([dynamic]string)` -> `make([dynamic]string, 5)`.
 
-12. **cmd_edit_config.odin:27** — `$EDITOR` used as single binary name. Breaks for multi-word values like `"code -w"`. Needs `strings.fields()`.
+15. Add a text filter to the multi_select.
 
-33. **config.odin:178** — `search_paths` silently ignores `os.user_home_dir` error. If home is empty, `~` isn't expanded. Same class of bug as issue 3.
+16. Create backup / fallback fd.
 
-35. **prompt.odin:124** — `make([dynamic]bool, len(options))` creates N zero-initialized elements. Works because `false` is the default, but same footgun as original issue 1. Should be `make([dynamic]bool, 0, len(options))`.
+17. Add tests for untested commands.
 
-39. Lots of memory leaks to fix.
+18. 2 scan tests silently skip when fd isn't installed, tests pass without actually testing anything. These should use #assert to be sure that fd is in path.
 
-## LOW
+19. Try to do all encryption / decryption in memory - only read / write encrypted data to disk.
 
-15. **db.odin:115** — `json.unmarshal_string` error not checked. Malformed JSON silently produces empty/partial data.
+20. add --format -f flag to commands that draw tables.
 
-16. **db.odin:352-353** — `hex.encode` error ignored. `string(hex_bytes)` aliases the byte slice.
+21. Replace `testing.expect` calls with `testing.expect_value` calls where appropriate.
 
-18. **config.odin:51-60** — `envr_dir` recomputes home dir on every call. Could cache.
+22. Change struct field names from PascalCase to snake_case.
 
-37. **cmd_sync.odin:80, cmd_list.odin:33, cmd_deps.odin:9** — `make([]string, 2)` for table rows never freed. Leaks per row. Defer to memory pass.
-
-## REFACTOR
-
-20. **cmd_list.odin** — Non-TTY branch builds `ListEntry` structs and marshals JSON separately. Now that `render_json_rows` (issue 1) accepts an `io.Writer` and uses `json.marshal`, unify both branches to use it. Note: will change JSON keys from `"directory"/"path"` to `"Directory"/"Path"`.

-
-24. Create backup / fallback fd.
-
-25. Add tests for untested commands.
-
-26. Add a global --config -c flag to use an alternate config.
-
-27. version --long Odin only prints version; Go also prints commit hash and build date
-
-28. 2 scan tests silently skip	Low	When fd isn't installed, tests pass without actually testing anything. These should use #assert to be sure that fd is in path.
-
-38. Try to do all encryption / decryption in memory - only read / write encrypted data to disk.
+23. procedures should be ordered by use, main at the top, then in the order they are called from main.
