2024-12-04tests: ignore pidfd in fd leak testJakob Unterwurzacher
This is not a real leak: fd leak in test process? before, after: [0r=/dev/null 3r=/proc/940141/fd 5rw=anon_inode:[eventfd] (filtered: pipe:[2454797], pipe:[2454797], anon_inode:[eventpoll])] [0r=/dev/null 3r=/proc/940141/fd 5rw=anon_inode:[eventfd] 12rw=anon_inode:[pidfd] (filtered: pipe:[2454797], pipe:[2454797], anon_inode:[eventpoll], pipe:[2460158])] Ignore pidfd.

2021-08-23go mod: declare module version v2Jakob Unterwurzacher
Our git version is v2+ for some time now, but go.mod still declared v1. Hopefully making both match makes https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work. All the import paths have been fixed like this: find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%
2021-08-20Implement -deterministic-names: extended -zerodirivJakob Unterwurzacher
-deterministc-names uses all-zero dirivs but does not write them to disk anymore.

2021-08-19test_helpers: actually use global testParentDir variableJakob Unterwurzacher
Typo inside doInit.
2021-08-19golangci-lint: fix issues found by gosimpleJakob Unterwurzacher
Everything except the if err2.Err == syscall.EOPNOTSUPP case. Gets too confusing when collapsed into a single line. Issues were: $ golangci-lint run --disable-all --enable gosimple mount.go:473:2: S1008: should use 'return strings.HasPrefix(v, "fusermount version")' instead of 'if strings.HasPrefix(v, "fusermount version") { return true }; return false' (gosimple) if strings.HasPrefix(v, "fusermount version") { ^ cli_args.go:258:5: S1002: should omit comparison to bool constant, can be simplified to `args.forcedecode` (gosimple) if args.forcedecode == true { ^ cli_args.go:263:6: S1002: should omit comparison to bool constant, can be simplified to `args.aessiv` (gosimple) if args.aessiv == true { ^ cli_args.go:267:6: S1002: should omit comparison to bool constant, can be simplified to `args.reverse` (gosimple) if args.reverse == true { ^ internal/stupidgcm/stupidgcm.go:227:6: S1002: should omit comparison to bool constant, can be simplified to `g.forceDecode` (gosimple) if g.forceDecode == true { ^ gocryptfs-xray/xray_tests/xray_test.go:23:5: S1004: should use !bytes.Equal(out, expected) instead (gosimple) if bytes.Compare(out, expected) != 0 { ^ gocryptfs-xray/xray_tests/xray_test.go:40:5: S1004: should use !bytes.Equal(out, expected) instead (gosimple) if bytes.Compare(out, expected) != 0 { ^ gocryptfs-xray/paths_ctlsock.go:34:20: S1002: should omit comparison to bool constant, can be simplified to `!eof` (gosimple) for eof := false; eof == false; line++ { ^ tests/reverse/xattr_test.go:19:2: S1008: should use 'return err2.Err != syscall.EOPNOTSUPP' instead of 'if err2.Err == syscall.EOPNOTSUPP { return false }; return true' (gosimple) if err2.Err == syscall.EOPNOTSUPP { ^ internal/fusefrontend/node.go:459:45: S1002: should omit comparison to bool constant, can be simplified to `!nameFileAlreadyThere` (gosimple) if nametransform.IsLongContent(cName2) && nameFileAlreadyThere == false { ^ tests/xattr/xattr_integration_test.go:221:2: S1008: should use 'return err2.Err != syscall.EOPNOTSUPP' instead of 'if err2.Err == syscall.EOPNOTSUPP { return false }; return true' (gosimple) if err2.Err == syscall.EOPNOTSUPP { ^ tests/test_helpers/helpers.go:338:19: S1002: should omit comparison to bool constant, can be simplified to `open` (gosimple) if err != nil && open == true { ^ tests/matrix/concurrency_test.go:121:7: S1004: should use !bytes.Equal(buf, content) instead (gosimple) if bytes.Compare(buf, content) != 0 { ^
2021-06-21nametransform: delete NameTransformer interfaceJakob Unterwurzacher
Useless layer of indirection.
2021-03-21test_helpers: VerifySize: don't complain about ino mismatchJakob Unterwurzacher
The inode number is not stable with `-sharedstorage`. Ignore it. Failure was like this: --- FAIL: TestFallocate (0.02s) helpers.go:229: Stat vs Fstat mismatch: st= {59 11543 1 33188 1026 1026 0 0 0 4096 8 {1616315569 838232716} {1616315569 838232716} {1616315569 838232716} [0 0 0]} st2={59 11545 1 33188 1026 1026 0 0 0 4096 8 {1616315569 838232716} {1616315569 838232716} {1616315569 838232716} [0 0 0]}
2021-03-20tests: MountOrFatal creates mnt dir itselfJakob Unterwurzacher
Allows to drop a few Mkdir()s.
2020-09-09test_helpers: print warning when not running on ext4Jakob Unterwurzacher
ext4 reuses inode numbers, tmpfs does not.
2020-09-09test_helpers: mark MountOrFatal as a Helper()Jakob Unterwurzacher
2020-08-15test_helper: VerifyExistence: don't panicJakob Unterwurzacher
Instead bubble up the error to the testing object.
2020-07-12v2api: fix Mkdir crash when using plaintextnamesJakob Unterwurzacher
2020-05-17dircache: increase cache size & lifetimeJakob Unterwurzacher
Looking at the dircache debug output, we see that a "git status" workload has a very bad cache hit rate because the entries expire or get evicted before they can be reused. Increase both cache size and lifetime for a 4x speedup: Before: 75s After: 17s https://github.com/rfjakob/gocryptfs/issues/410
2020-05-10Fix spelling mistakes found by misspellJakob Unterwurzacher

2020-05-10gocryptfs-xray: add -0 flag, add testsJakob Unterwurzacher
The -0 flags works like xargs -0.
2020-05-09test_helpers: use new ctlsock.CtlSock APIJakob Unterwurzacher
2020-05-09test_helper: kill lsof after 1 secondJakob Unterwurzacher
lsof may get stuck when gocryptfs itself is stuck.
2020-05-09ctlsock: create exported ctlsock client libraryJakob Unterwurzacher
The former interal ctlsock server package is renamed to ctlsocksrv.
2020-05-09tests: use t.Name()Jakob Unterwurzacher
We did not use t.Name() as it was not available before Go 1.8. Now the oldest Go version we support is Go 1.11, so we can use it.
2019-11-16tests: also check inode number in VerifySizeJakob Unterwurzacher
Check Stat() vs Fstat() result. Not very useful at the moment as the kernel never seems to call Fstat().
2019-10-06tests: use /var/tmp by defaultJakob Unterwurzacher
On Fedora, /tmp is tmpfs, which behaves differently than ext4 (inode numbers are never reused, for example). Use /var/tmp, which is ext4 on Fedora, to get a more realistic test environment. This also allows us to drop the xattr workaround.
2019-10-06tests: filter leaked fds by prefixJakob Unterwurzacher
When running $ go test ./tests/matrix/ in isolation, it failed like this: fd leak? before, after: [0r=/dev/null 3w=/dev/null 5r=/proc/8078/fd (hidden:4)] [0r=/dev/null 3w=/dev/null 5w=/tmp/go-build366655199/b001/testlog.txt 7r=/proc/8078/fd (hidden:4)] Filter by prefix to get rid of this spurious test failure.
2019-10-06tests: clarify which process seems to be leaking fdsJakob Unterwurzacher
The tests check if they leak fds themselves, but we also check if gocryptfs leaks fds. Clarify what is what in the error message.
2019-09-08test_helpers: ListFds: handle an exited process gracefullyJakob Unterwurzacher
This used to dump a backtrace to the console which obscured what is going on.
2019-05-01tests: fix root_test permission issuesJakob Unterwurzacher
The parent directories need execute all permissions.
2019-05-01tests: split testParentDir by UIDJakob Unterwurzacher
When we run tests as root, they will leave root-owned files in testParentDir, which causes trouble when we run tests as a normal user later on. Split by UID.
2019-05-01test_helpers: better function comments for InitFS and MountJakob Unterwurzacher
It's confusing that you must pass "-extpass" for Mount but not for InitFS. Note that in the comment.
2019-01-20tests: check that we can delete directories with all permissionJakob Unterwurzacher
Regression test for https://github.com/rfjakob/gocryptfs/issues/354
2019-01-15tests: Increase timeout in Mount() function.Sebastian Lackner
This avoids sporadic test failures on macOS.
2019-01-14tests: reduce noise on MacOSJakob Unterwurzacher
This should get rid of Openat: O_NOFOLLOW missing: flags = 0x0 Fchmodat: adding missing AT_SYMLINK_NOFOLLOW flag sys_common_test.go:203: chmod on symlink should have failed, but did not. New mode=0333 UnmountErr: "[...]/057376762.mnt" was not found in MountInfo, cannot check for FD leak and add some context to --- FAIL: TestUtimesNano (0.00s) matrix_test.go:628: no such file or directory See https://github.com/rfjakob/gocryptfs/pull/343#issuecomment-453888006 for full test output
2019-01-05A few more spelling fixes.Sebastian Lackner
2019-01-04tests: bump maxCacheFds to 3Jakob Unterwurzacher
As the dirCache now has 3 entries, the tests should accept up to 3 extra fds without declaring an fd leak.
2019-01-04tests: fix VerifyExistence() helper, it missed unstat()able filesJakob Unterwurzacher
VerifyExistence missed unstat()able files in the directory listing because ioutil.ReadDir() filtered them out. https://github.com/rfjakob/gocryptfs/issues/285
2019-01-03Omit syscall.O_RDONLY flag when passing O_PATH.Sebastian Lackner
When O_PATH is specified in flags, flag bits other than O_CLOEXEC, O_DIRECTORY, and O_NOFOLLOW are ignored.
2019-01-03tests: allow one extra fd in fd leak detector (dirCache)Jakob Unterwurzacher
The gocryptfs process may keep one fd open for up to one second in the dirCache.
2019-01-03nametransform: simplify WriteDirIV to WriteDirIVAtJakob Unterwurzacher
Un-spaghettify the function and let the callers open the directory.
2019-01-02tests: retry longer when we see a fd leakJakob Unterwurzacher
Hopefully gets rid of the false positives on travis.
2019-01-02tests: add fd leak retry logic to UnmountErr, really return errorJakob Unterwurzacher
Give the gocryptfs process one extra millisecond to close files. Allows us to drop several other sleeps. UnmountErr now really returns an error when it detects an fd leak instead of just printing a message.
2019-01-02tests: ListFds(): filter out pipe and eventpoll fdsJakob Unterwurzacher
These are created on demand by the Go runtime and are usually not interesting.
2019-01-02tests: make MountInfo field accessibleJakob Unterwurzacher
Tests outside the test_helpers package may want to look at this.
2019-01-01tests: ListFds: show r/w statusJakob Unterwurzacher
Also, drop entries that disappear while we stat them.
2019-01-01tests: split mount_unmount.go from helpers.goJakob Unterwurzacher
With the FD leak logic, the mount/unmount functions have become complex enough to give them their own file.
2019-01-01tests: detect fd leaks on unmountJakob Unterwurzacher
For now, this only prints a message but does not fail the tests.
2019-01-01tests: teach ListFds() to check other processesJakob Unterwurzacher
2019-01-01tests: save gocryptfs process id in test_helpers.MountPIDJakob Unterwurzacher
This will allow to tests to monitor fd usage and maybe other things.
2018-10-10tests: respect TMPDIR if setJakob Unterwurzacher
Setting TMPDIR now allows to run the tests against a directory of your choice, making it easier to test different filesystems.
2018-09-23fusefrontend: get rid of os.File* wrappingJakob Unterwurzacher
Directly use int file descriptors for the dirfd and get rid of one level of indirection.
