fix(exclude): keep wildcards when stripping a trailing slash - #328
excluding_files() normalizes directory patterns by calling pattern.rstrip('/*'). rstrip takes a character set, so it removes every trailing / and *, not just the /* suffix. A pattern like build*/ becomes build, which matches no directory, so nothing under build_out/ is excluded. build* (no slash) works, which makes the behavior inconsistent.
Repro:
# tree: build_out/a.c, src/b.cexcluding_files(['build*/'], path) # [] before, ['build_out/a.c'] afterexcluding_files(['build*'], path) # ['build_out/a.c'] in both
The fix strips exactly one trailing /* or /. sample/, sample/* and sample keep working as before.
Tests
Added tests/test_exclude.py; the wildcard case fails on main and passes with the fix.
pytest in tests/: 261 passed. The 4 failures are the git clone/network tests in test_download.py, unrelated to this change.
flake8 src clean.
Summary by CodeRabbit
Bug Fixes
Exclusion patterns now handle trailing slashes and /* consistently without removing other trailing wildcard characters.
Directory-only patterns exclude files inside matching directories without matching similarly named files. General patterns can match both file paths and filenames.
Tests
Added coverage for directory and file exclusion patterns with and without trailing slashes and wildcards.
excluding_files() normalized 'build*/' with rstrip('/*'), which removes
every trailing '/' and '*' and leaves 'build'. The pattern then matched
no directory. Strip only the trailing '/*' or '/' instead.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
excluding_files and get_excluded_paths now distinguish directory-only patterns from general patterns. They normalize separators and trailing slashes, skip empty patterns, and match directories, descendant paths, relative file paths, and basenames according to pattern type. Tests cover slash variants and similarly named files.
Changes: Exclude pattern handling
Layer / File(s)
Summary
Pattern normalization, matching, and tests src/fosslight_util/exclude.py, tests/test_exclude.py
Both helpers separate directory-only patterns from general patterns and normalize trailing slashes. Directory-only patterns match directories and their descendants. General patterns match relative file paths and basenames. Tests cover slash variants and similarly named files.
The changes preserve wildcard directory exclusions while distinguishing them from file patterns. The remaining leading ./ limitation predates this change; no new merge-blocking issue is established.

Explanation
The title names the change: stripping a trailing slash from exclusion patterns no longer removes wildcard characters, so patterns such as build*/ keep working. The changeset matches this. The raw summary says excluding_files and get_excluded_paths now separate directory-only patterns from general patterns, normalize trailing slashes, and skip empty patterns. The PR objectives describe the rstrip('/') bug that reduced build/ to build, and the added tests cover build*/ and sample/. The title is specific and scoped to the main fix. The 'fix' prefix matches the bug-fix intent. The changes go beyond stripping one slash, because they also split directory and general pattern handling. The title still covers the primary defect.

Strip all trailing slashes after removing a trailing '/*', preserving wildcards in the directory name while ensuring repeated trailing slashes (e.g., 'sample//') normalize correctly.

@mangeshraut712 , excluding_files looks like a legacy function. Current Source, Binary, Dependency, and FL Scanner do not call it, so the changes inside it do not affect -e. Please drop those changes, including the excluding_files tests.
The rstrip('/') bug is real: it treats the argument as a character set, so build/ becomes build. The live path is get_excluded_paths. That function only rewrites a pattern when it ends with /, so build/ stays build*/ and does not match build_out. Please apply this normalization there: if the pattern ends with /, drop those two characters, then strip any remaining trailing /. Moving rstrip('/') into get_excluded_paths would turn build*/ into build again.
Please test this through get_excluded_paths. build*/, build*//, and build*/* should exclude build_out and build_out/a.c.
Strip trailing '/*' and '/' from custom_excluded_paths in
get_excluded_paths() so that wildcard patterns with trailing slashes
(e.g., 'build*/', 'build*/*') match directories and files
properly during scanner -e execution.
Add tests for get_excluded_paths covering trailing slashes and stars.

@soimkim Addressed in 355046b: updated get_excluded_paths() to normalize custom_excluded_paths by stripping trailing /* and /, matching both directory basenames and relative paths with fnmatch, and handling pattern + '/*' for files. Added tests in tests/test_exclude.py covering get_excluded_paths() with trailing slashes and wildcards (build*/, build*//, build*/*, sample/, sample/*, etc.).
The root-level test can pass without directory-basename matching. Add a nested directory to test that matching path.

Normalize leading ./ in exclusion patterns.
When a caller supplies ./build/ or ./build*/, both exclusion functions retain the prefix, but their relative paths omit it. The directory and its files are not excluded. Remove the leading ./ before matching in both functions.

The test only checks the top-level build_out, so it still passes if nested directory-name matching breaks. It also does not verify that the same exclusion is applied through FL Scanner's -e path. Please add tests for a nested directory and for the fosslight_scanner-e result.

Thank you @soimkim! Added both test suites in commit 2d5e721:
Nested directory and deep matching coverage in tests/test_exclude.py, verifying nested matches (e.g. pkg/build_out/nested.c and deeper descendants) for directory-only patterns vs general wildcards and explicitly scoped relative paths (pkg/build*/).
Integration test in tests/test_exclude_scanner.py (test_scanner_cli_reports_nested_directory_exclusions) that executes the real fosslight_scanner CLI with -e over nested paths and verifies both the Excluded path list in the generated Excel report and the resulting scanned file count.
Also preserved the legacy excluding_files helper intact. Ready for your review!
excluding_files is unused. Current Source, Binary, Dependency, and FL Scanner call get_excluded_paths for -e. Please revert every change in excluding_files, including its tests. Further edits there do not change -e.
Please keep the new behavior only in get_excluded_paths, and make that path one normalization step:
If a pattern ends with /*, drop those two characters, then strip any remaining trailing /.
A pattern that arrived with a trailing / or /* is directory-only. It matches a directory's relative path or basename, and files under that directory. It does not match a sibling file such as build_report.c.
Any other pattern matches both directories and file basenames.
fnmatch already covers an exact name, so the separate membership check can go away.
build*/ should exclude build_out/a.c and src/build_out/b.c, and leave build_report.c in place. build* should exclude build_report.c as well. Please cover those cases in tests/test_exclude.py through get_excluded_paths.
Restore the legacy excluding_files helper to the base implementation.
Keep get_excluded_paths coverage for root, nested and deep directory
matches, file patterns and explicitly scoped relative paths.
Add optional real fosslight_scanner -e tests that inspect the generated
report's excluded paths and scanned-file count.

@soimkim Pushed 65a98e0 for the remaining point from your Nov 9 comment: the separate rel_path in ... / dir_name in ... membership branch in get_excluded_paths is gone, so directory matching is one any() over rel_path and the basename.
One note on why equality is still inside that any(): fnmatch reads [...] as a character class, so a literal directory named a[1] stops matching a[1]/ once the exact-name check is removed (main excludes it today). I kept name == pattern next to fnmatch to avoid that regression and added test_literal_directory_name_with_glob_characters. Happy to drop it if you would rather not support that case.
excluding_files is unchanged from main. tests/test_exclude.py 13 passed; full suite 275 passed, 1 skipped with tests/test_download.py deselected (those clone from the network, which my environment blocks); flake8 clean.
Drop the separate membership branch in get_excluded_paths as requested
in review. Equality stays inside the same any() so directory names with
glob characters (for example a[1]) are still excluded literally.
