69d88505fd7f4cb0d9e4f1918de296342fe05858 go mod: declare module version v2
translated all instances of "github.com/rfjakob/gocryptfs/" to
"github.com/rfjakob/gocryptfs/v2/".
Unfortunately, this included hyperlinks.
Unbreak the hyperlinks like this:
find . -name \*.go | xargs sed -i s%https://github.com/rfjakob/gocryptfs/v2/%https://github.com/rfjakob/gocryptfs/v2/%
|
|
|
|
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/%
|
|
-deterministc-names uses all-zero dirivs but does not write
them to disk anymore.

Except xattrSupported, this is a false positive.

gocryptfs 2.0 introduced the regression that the size
reported at symlink creation was the ciphertext size,
which is wrong.
Report the plaintext size.

matrix_test.go:354: Write failed

|
|
Instead bubble up the error to the testing object.
|
|
Chasing a bug that seems to have nothing to do
with magic names, as it already triggers during
warmup:
--- FAIL: TestMagicNames (0.00s)
matrix_test.go:773: Testing n="warmup1"
matrix_test.go:773: Testing n="warmup2"
matrix_test.go:820: no such file or directory

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.
|
|
Just writing zeros carries the risk of not detecting
wrongly created file holes. Write random data instead.
|
|
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.
|
|
The tests check if they leak fds themselves, but we also
check if gocryptfs leaks fds. Clarify what is what in the
error message.
|
|
Test if https://github.com/rfjakob/gocryptfs/pull/413 works
as intended.
|
|
Before: ok github.com/rfjakob/gocryptfs/tests/matrix 18.560s
After: ok github.com/rfjakob/gocryptfs/tests/matrix 13.425s

Another attempt to find out what is going on behind
https://github.com/rfjakob/gocryptfs/issues/363
|
|
Try to find out what goes wrong in
https://github.com/rfjakob/gocryptfs/issues/363
|
|
Error was:
tests/matrix/matrix_test.go:101:9: no new variables on left side of :=
|
|
Should help debugging https://github.com/rfjakob/gocryptfs/issues/363
|
|
Looks like we allowed creating longer names by accident.
Fix that, and add a test that verifies it.
|
|
matrix_test.go is already too big.
|
|
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

|
|
Document what "d" and "h" means in the fancy ASCII diagrams.
https://github.com/rfjakob/gocryptfs/pull/326
|
|
|
|
This will allow to tests to monitor fd usage and maybe other things.
|
|
Make Access() symlink-safe through use of faccessat.
|
|
Instead of reporting the consequence:
matrix_test.go:906: modeHave 0664 != modeWant 0777
Report it if chmod itself fails, and also report the old file mode:
matrix_test.go:901: chmod 000 -> 777 failed: bad file descriptor
|
|
Go 1.7 does not have t.Name() yet.
|
|
Makes sure we don't add regressions when fixing
https://github.com/rfjakob/gocryptfs/issues/259
|
|
The function seems to have been renamed by 426b9536 by mistake.
Rename it back so the test is run again.
|
|
One fd leak found in TestMountBackground.
|
|
And fix two in test_helpers.Mount().
Leftover fds can cause an unmount failure like this later:
fusermount: failed to unmount /tmp/gocryptfs-test-parent/873632270/default-plain: Device or resource busy
so try to catch them early.
|
|
These can cause EBUSY errors when unmounting.
|
|
macos does not have lazy unmount, so let's not use it
on linux either.
If the unmount fails, run "lsof" to find the open file.
Also fix the first bug we found this way.
|
|
Fixes test-without-openssl.bash.
|
|
Not supported on macos.
Beef up the first test case a little by using different second
values.
|
|
|
|
We relied on the finalizer to close a few fds.
For some reason, this did not cause problems on Linux,
but on MacOS, it causes unmount failures:
umount(/private/tmp/gocryptfs-test-parent/194654785/default-plain): Resource busy -- try 'diskutil unmount'
|
|
Gets rid of the touch error message upon running the tests.
|
|
These cannot work on MacOS.
|
|
gocryptfs.longname.XXX files were considered magic in PlaintextNames
mode, which was wrong.
Fix that and add tests.
Fixes https://github.com/rfjakob/gocryptfs/issues/174
|
|
In PlaintextNames mode the "gocryptfs.longname." prefix does not have any
special meaning.
https://github.com/rfjakob/gocryptfs/issues/174
|
|
In PlaintextNames mode the "gocryptfs.longname." prefix does not have any
special meaning. We should not attempt to delete any .name files.
