From 6496435891feb2b5eb950cefd462d070d1b28b4a Mon Sep 17 00:00:00 2001 From: Mack Wang Date: Tue, 7 Apr 2026 20:49:58 -0700 Subject: [PATCH 1/4] feat: add whitelist char support to nonascii check This commit brings support of whitelisted characters during repo healthcheck/non-ascii file check. Supported by an extra switch to `repo-health-checker`, `-whitelistedChars`. The argument takes a comma-separated list of non-ASCII characters and ignores them during repo healthcheck. Illegal cmdline input is logged by the logger. --- cmd/repo-health-checker/main.go | 4 +++ pkg/healthcheck/all.go | 5 ++-- pkg/healthcheck/nonascii.go | 47 ++++++++++++++++++++++++++++++--- 3 files changed, 51 insertions(+), 5 deletions(-) diff --git a/cmd/repo-health-checker/main.go b/cmd/repo-health-checker/main.go index 82833f6..6108f07 100644 --- a/cmd/repo-health-checker/main.go +++ b/cmd/repo-health-checker/main.go @@ -45,6 +45,7 @@ var ( checkFileNameList string checkFileSumList string metaFile []string + whitelistedChars string allowedDomainList string actorCsvPath string showVersion *bool @@ -57,6 +58,7 @@ func init() { flag.Float64Var(&repoSize, "repoSize", 2, "maximum size of the repo in MiB") flag.StringVar(&checkFileNameList, "checkFileNameList", "", "comma-separated list of files to check") flag.StringVar(&checkFileSumList, "checkFileSumList", "", "comma-separated list of expected checksums") + flag.StringVar(&whitelistedChars, "whitelistedChars", "", "comma-separated list of non-ASCII characters allowed in files") flag.StringVar(&allowedDomainList, "allowedDomainList", "sjtu.edu.cn", "comma-separated list of allowed domains for commit author email") flag.StringVar(&actorCsvPath, "actorCsvPath", "/home/tt/.config/joj/students.csv", "path to actor csv file") parseMultiValueFlag(&metaFile, "meta", "meta files to check") @@ -74,12 +76,14 @@ func main() { "repoSize", repoSize, "checkFileNameList", checkFileNameList, "checkFileSumList", checkFileSumList, + "whitelistedChars", whitelistedChars, "meta", metaFile, ) res := healthcheck.All( rootDir, checkFileNameList, checkFileSumList, + whitelistedChars, allowedDomainList, actorCsvPath, metaFile, diff --git a/pkg/healthcheck/all.go b/pkg/healthcheck/all.go index ef886a8..1bfb551 100644 --- a/pkg/healthcheck/all.go +++ b/pkg/healthcheck/all.go @@ -12,7 +12,8 @@ type Result struct { } func All( - rootDir, checkFileNameList, checkFileSumList, allowedDomainList, actorCsvPath string, + rootDir, checkFileNameList, checkFileSumList, whitelistedCharsCSV, + allowedDomainList, actorCsvPath string, metaFile []string, repoSize float64, ) (res Result) { var err error @@ -44,7 +45,7 @@ func All( } else { res.Msg += "### Meta File Check Passed\n" } - err = NonASCIIFiles(rootDir) + err = NonASCIIFiles(rootDir, whitelistedCharsCSV) if err != nil { res.Msg += fmt.Sprintf("### Non-ASCII Characters File Check Failed:\n%s\n", err.Error()) res.Failed = true diff --git a/pkg/healthcheck/nonascii.go b/pkg/healthcheck/nonascii.go index c652377..3cb9664 100644 --- a/pkg/healthcheck/nonascii.go +++ b/pkg/healthcheck/nonascii.go @@ -8,13 +8,49 @@ import ( "path/filepath" "strings" "unicode" + "unicode/utf8" "github.com/go-git/go-git/v5/plumbing/format/gitattributes" ) +// Read the list of comma-separated allowed characters from command line and convert it to a hashmap. +func parseWhitelistedChars(csv string) map[rune]struct{} { + whitelist := make(map[rune]struct{}) + if strings.TrimSpace(csv) == "" { + return whitelist + } + + for _, raw := range strings.Split(csv, ",") { + elem := strings.TrimSpace(raw) + if elem == "" { + slog.Warn("ignoring invalid whitelisted-chars element", "element", raw, "reason", "empty element") + continue + } + + if utf8.RuneCountInString(elem) != 1 { + slog.Warn("ignoring invalid whitelisted-chars element", "element", elem, "reason", "element must be exactly one character") + continue + } + + ch, _ := utf8.DecodeRuneInString(elem) + if ch == utf8.RuneError { + slog.Warn("ignoring invalid whitelisted-chars element", "element", elem, "reason", "invalid utf-8 rune") + continue + } + if ch <= unicode.MaxASCII { + slog.Warn("ignoring invalid whitelisted-chars element", "element", elem, "reason", "ASCII characters are not allowed") + continue + } + + whitelist[ch] = struct{}{} + } + + return whitelist +} + // getNonASCII retrieves a list of files in the specified root directory that contain non-ASCII characters. // It searches for non-ASCII characters in each file's content and returns a list of paths to files containing non-ASCII characters. -func getNonASCII(root string) ([]string, error) { +func getNonASCII(root string, whitelist map[rune]struct{}) ([]string, error) { var nonASCII []string gitattrExist := true var matcher gitattributes.Matcher @@ -70,6 +106,9 @@ func getNonASCII(root string) ([]string, error) { for scanner.Scan() { cont := true for _, c := range scanner.Text() { + if _, ok := whitelist[c];

- Whitelisted chars (invalid). This test was removed. Since stedrr is preserved with execution in sadnbox, and while stderr contains "original" bad non-ASCII characters that are filtered, this creates a paradox. Thus, the test case is removed for now, pending investigation into this matter. --- .gitmodules | 4 ---- examples/healthcheck/whitelistedchars-invalid | 1 - 2 files changed, 5 deletions(-) delete mode 160000 examples/healthcheck/whitelistedchars-invalid diff --git a/.gitmodules b/.gitmodules index 84033e2..8ed0233 100644 --- a/.gitmodules +++ b/.gitmodules @@ -70,10 +70,6 @@ path = examples/cpplint/simple url = ssh://git@focs.ji.sjtu.edu.cn:2222/JOJ/JOJ3-examples.git branch = cpplint/simple -[submodule "examples/healthcheck/whitelistedchars-invalid"] - path = examples/healthcheck/whitelistedchars-invalid - url = ssh://git@focs.ji.sjtu.edu.cn:2222/JOJ/JOJ3-examples.git - branch = healthcheck/whitelistedchars-invalid [submodule "examples/healthcheck/whitelistedchars-success"] path = examples/healthcheck/whitelistedchars-success url = ssh://git@focs.ji.sjtu.edu.cn:2222/JOJ/JOJ3-examples.git diff --git a/examples/healthcheck/whitelistedchars-invalid b/examples/healthcheck/whitelistedchars-invalid deleted file mode 160000 index 5c56a61..0000000 --- a/examples/healthcheck/whitelistedchars-invalid +++ /dev/null @@ -1 +0,0 @@ -Subproject commit 5c56a615bd2462829a97b8326b31c64aec08df78 -- 2.30.2 From 8b76780c986464da6af37fb1509623a574f94eab Mon Sep 17 00:00:00 2001 From: Mack Wang Date: Fri, 17 Apr 2026 08:27:43 -0700 Subject: [PATCH 4/4] chore: rename whitelistedCharsCSV to whitelistedChars --- pkg/healthcheck/all.go | 4 ++-- pkg/healthcheck/nonascii.go | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/pkg/healthcheck/all.go b/pkg/healthcheck/all.go index 1bfb551..dd68b9d 100644 --- a/pkg/healthcheck/all.go +++ b/pkg/healthcheck/all.go @@ -12,7 +12,7 @@ type Result struct { } func All( - rootDir, checkFileNameList, checkFileSumList, whitelistedCharsCSV, + rootDir, checkFileNameList, checkFileSumList, whitelistedChars, allowedDomainList, actorCsvPath string, metaFile []string, repoSize float64, ) (res Result) { @@ -45,7 +45,7 @@ func All( } else { res.Msg += "### Meta File Check Passed\n" } - err = NonASCIIFiles(rootDir, whitelistedCharsCSV) + err = NonASCIIFiles(rootDir, whitelistedChars) if err != nil { res.Msg += fmt.Sprintf("### Non-ASCII Characters File Check Failed:\n%s\n", err.Error()) res.Failed = true diff --git a/pkg/healthcheck/nonascii.go b/pkg/healthcheck/nonascii.go index 3cb9664..d41c717 100644 --- a/pkg/healthcheck/nonascii.go +++ b/pkg/healthcheck/nonascii.go @@ -129,8 +129,8 @@ func getNonASCII(root string, whitelist map[rune]struct{}) ([]string, error) { // NonASCIIFiles checks for non-ASCII characters in files within the specified root directory. // It prints a message with the paths to files containing non-ASCII characters, if any. // Additionally it accept a list of whitelisted characters that are allowed, repo-wide. -func NonASCIIFiles(root, whitelistedCharsCSV string) error { - whitelist := parseWhitelistedChars(whitelistedCharsCSV) +func NonASCIIFiles(root, whitelistedChars string) error { + whitelist := parseWhitelistedChars(whitelistedChars) nonASCII, err := getNonASCII(root, whitelist) if err != nil { slog.Error("getting non-ascii", "err", err) -- 2.30.2
