From 7512c95fa3f4b4e4ccdf452024f314a9a3c3b60f Mon Sep 17 00:00:00 2001 From: Bernhard Guillon Date: Mon, 6 Jul 2026 21:21:53 +0200 Subject: Add sync and gitignore tests, fix loadGitignore bug - Added gitignore_test.go: comprehensive tests for go-gitignore patterns - Verified: *, **, [], negation, anchored patterns, comments - Documented limitation: ? wildcard not supported by go-gitignore - Added sync_test.go: integration tests for initial sync - Tests: basic files, gitignore excludes, negation, double-star, directory patterns, symlinks, permissions, dry-run, .git skip, nested gitignore, complex combined patterns - Fixed gitignore.go: use CompileIgnoreFile instead of passing entire file content as single string to CompileIgnoreLines --- sync_test.go | 391 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 391 insertions(+) create mode 100644 sync_test.go (limited to 'sync_test.go') diff --git a/sync_test.go b/sync_test.go new file mode 100644 index 0000000..758d4ec --- /dev/null +++ b/sync_test.go @@ -0,0 +1,391 @@ +package main + +import ( + "os" + "path/filepath" + "sort" + "testing" + + ignore "github.com/sabhiram/go-gitignore" +) + +func TestInitialSync_BasicFiles(t *testing.T) { + host := t.TempDir() + data := t.TempDir() + + writeFile(t, host, "a.txt", "hello") + writeFile(t, host, "b.txt", "world") + writeFile(t, host, "sub/c.txt", "nested") + + rules := ignore.CompileIgnoreLines() + + manifest, err := initialSync(host, data, rules, false) + if err != nil { + t.Fatal(err) + } + + assertFileExists(t, data, "a.txt", "hello") + assertFileExists(t, data, "b.txt", "world") + assertFileExists(t, data, "sub/c.txt", "nested") + assertManifestContains(t, manifest, "a.txt", "b.txt", "sub/c.txt") +} + +func TestInitialSync_GitignoreExcludes(t *testing.T) { + host := t.TempDir() + data := t.TempDir() + + writeFile(t, host, ".gitignore", "*.log\nbuild/\n") + writeFile(t, host, "app.go", "package main") + writeFile(t, host, "debug.log", "logs here") + writeFile(t, host, "build/output.o", "binary") + + rules, err := loadGitignore(host) + if err != nil { + t.Fatal(err) + } + + manifest, err := initialSync(host, data, rules, false) + if err != nil { + t.Fatal(err) + } + + assertFileExists(t, data, "app.go", "package main") + assertFileNotExists(t, data, "debug.log") + assertFileNotExists(t, data, "build/output.o") + assertManifestContains(t, manifest, "app.go") + assertManifestNotContains(t, manifest, "debug.log", "build/output.o") +} + +func TestInitialSync_NegationPattern(t *testing.T) { + host := t.TempDir() + data := t.TempDir() + + writeFile(t, host, ".gitignore", "*.log\n!important.log\n") + writeFile(t, host, "debug.log", "debug") + writeFile(t, host, "important.log", "important") + + rules, err := loadGitignore(host) + if err != nil { + t.Fatal(err) + } + + _, err = initialSync(host, data, rules, false) + if err != nil { + t.Fatal(err) + } + + assertFileNotExists(t, data, "debug.log") + assertFileExists(t, data, "important.log", "important") +} + +func TestInitialSync_DoubleStar(t *testing.T) { + host := t.TempDir() + data := t.TempDir() + + writeFile(t, host, ".gitignore", "**/temp\n") + writeFile(t, host, "src/main.go", "code") + writeFile(t, host, "temp/cache", "cached") + writeFile(t, host, "a/b/temp/data", "temp data") + + rules, err := loadGitignore(host) + if err != nil { + t.Fatal(err) + } + + _, err = initialSync(host, data, rules, false) + if err != nil { + t.Fatal(err) + } + + assertFileExists(t, data, "src/main.go", "code") + assertFileNotExists(t, data, "temp/cache") + assertFileNotExists(t, data, "a/b/temp/data") +} + +func TestInitialSync_DirectoryPattern(t *testing.T) { + host := t.TempDir() + data := t.TempDir() + + writeFile(t, host, ".gitignore", "node_modules/\n") + writeFile(t, host, "src/app.js", "code") + writeFile(t, host, "node_modules/pkg/index.js", "pkg") + + rules, err := loadGitignore(host) + if err != nil { + t.Fatal(err) + } + + _, err = initialSync(host, data, rules, false) + if err != nil { + t.Fatal(err) + } + + assertFileExists(t, data, "src/app.js", "code") + assertFileNotExists(t, data, "node_modules/pkg/index.js") +} + +func TestInitialSync_Symlinks(t *testing.T) { + host := t.TempDir() + data := t.TempDir() + + writeFile(t, host, "target.txt", "target content") + if err := os.Symlink("target.txt", filepath.Join(host, "link.txt"));
