* feat(gptel-tools): harden path validation with file-truename realpathCraig Jennings2026-05-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | Resolves PATH through file-truename before applying home-directory and read/write checks across the path-handling tools (git_status, git_log, git_diff, move_to_trash, read_text_file, update_text_file, write_text_file, list_directory_files, read_buffer, web_fetch). Without the resolve step, a symlink under HOME pointing outside HOME would pass the prefix check but the tool would act on the real target -- a symlink-escape. move_to_trash also tightens the trash-bin construction (treats empty file extensions correctly) and switches the "critical directories" list to truename-resolved canonical forms so a symlinked ~/.config can't be trashed via an aliased path. update_text_file fixes an off-by-one in the line-count derivation when the source content is empty. Each source change pairs with tests in tests/test-gptel-tools-*.el and tests/test-update-text-file.el covering the realpath escape paths, the empty-extension trash case, and the empty-content line- count edge. Combined coverage is now 100% across all ten gptel-tools source files: 516 / 516 executable lines, 217 tests.
* test(gptel-tools): cover the helpers across the five remaining toolsCraig Jennings2026-05-161-10/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gptel-tools files had zero direct coverage outside of `update_text_file`, which landed with its rewrite earlier this session. This commit adds 52 tests across the five other tools. For three of the tools the helpers were already top-level defuns (`read_text_file`, `list_directory_files`, `move_to_trash`). The other two had their main bodies inlined into the `gptel-make-tool` lambda -- I extracted them so the work is testable without mocking gptel itself: read_buffer.el -> `cj/read-buffer--get-content` write_text_file.el -> `cj/write-text-file--run` plus `--validate-path`, `--backup-name`, `--ensure-parent` Test files, by tool: - read_buffer.el (5 tests): normal, empty, buffer-object, text-property-stripping, missing buffer. - write_text_file.el (10 tests): validate-path, backup-name shape, ensure-parent (creates missing / rejects unwritable), run with normal / overwrite / existing-no-overwrite / empty content / outside-home. - read_text_file.el (12 tests): validate-file-path (normal + three error shapes), metadata plist shape, size limits (no-op / hard cap / warning bypass with no-confirm), binary detection (text vs null-byte), special-type EPUB and generic-binary paths. - list_directory_files.el (15 tests): mode-to-permissions (file / dir / executable), get-file-info (file / directory), extension filter (keep / drop / always-dir / nil-extension), format-file- entry, list-directory flat / recursive / error, format-output with and without files. - move_to_trash.el (10 tests): unique-name (no conflict / conflict with timestamp / no-extension), validate-path (HOME / /tmp / outside / critical-dir / missing), perform on file and directory. Each test file uses the same load-path / gptel-stub idiom (`eval-and-compile` block, gptel stub when the real package isn't available) so the byte-compile hook is happy.
