Support truncate(2) by opening the file and calling ftruncate(2)
While the glibc "truncate" wrapper seems to always use ftruncate, fsstress from
xfstests uses this a lot by calling "truncate64" directly.

This file was forgotten in commit
"tests: make tests for unsupported FSs more compact".

The GCMIV128 feature flag is already mandatory, dropping the command
line option is the final step.
Completes https://github.com/rfjakob/gocryptfs/issues/29 .
|
|
There is no need to test that deprecated command-line options
produce an error. I trust the flags package.
Also split the example_filesystem helper functions into a
separate file.
|
|
The EMENames feature flag is already mandatory, dropping the command
line option is the final step.
|
|
As DirIV is now mandatory there is no user for the noiv functions.

The DirIV feature flag is already mandatory, dropping the command

The v0.6-plaintextnames example FS lacks the GCMIV128 feature
flag, is no longer mountable and can no longer be used for testing.
Add a new "-plaintextnames" filesystem created by gocryptfs v0.7.
There have been no format changes to "-plaintextnames" since then.
|
|
If it is, append "-dirty" to the hash.
|
|
|
|
|
|
As v0.4 introduced ext4-style feature flags, the on-disk format version
is unlinkely to change. Drop it from the version output to reduce
clutter. Use "gocryptfs -version -debug" to see it.
Add the Go version string because only Go 1.6 and newer have an optimized
AES-GCM implementation. This will help users to understand the performance
of their build.

|
|
Go 1.3.3 does not support testing.M, so skip the tests there.
|
|
|
|
The release of v0.12 is delayed to give people more time to
upgrade using "mv" or "rsync --remove-source-files".
|
|
The v0.6 and older example filesystem are mounted read-only
because they are deprecated, so skip the read-write tests.
|
|
This is part of the phase-out of very old filesystems.
See https://github.com/rfjakob/gocryptfs/wiki/Compatibility for
more info.
|
|
Recreate the files so they carry all feature flags.
Also, create them with "-scryptn 10" to speed up the tests.
|
|
extpass_test and example_filesystems_test did it wrong,
always returning 0.
|
|
From the man page:
**-ro**
: Mount the filesystem read-only
Also add a test.

Let's have shorter names, and merge *_api.go into the "main"
file.
No code changes.
|
|
tlog is used heavily everywhere and deserves a shorter name.
Renamed using sed magic, without any manual rework:
find * -type f -exec sed -i 's/toggledlog/tlog/g' {} +
|
|
We want to use colored error messages also outside of main,
so let's handle it in the logging package.
The fatal logger now automatically prints red.
|
|
* Supports stdin
* Add tests for extpass and stdin
As per user request at https://github.com/rfjakob/gocryptfs/issues/30
|
|
Also, capture all stderr and stdout but pass "-q".
This way we get to see error messages if there are any, or
spurious output when there should be none due to "-q".
|
|
This used to fail in an ugly way:
$ ./build.bash
./build.bash: line 13: go: command not found
./build.bash: line 15: [: too many arguments
./build.bash: line 20: go: command not found

If /proc/self/fd/X did not exist, the actual error is that the file
descriptor was invalid.
go-fuse's pathfs prefers using an open fd even for path-based operations
but does not take any locks to prevent the fd from being closed.
Instead, it retries the operation by path if it get EBADF. So this
change allows the retry logic to work correctly.
This fixes the error
rsync: failed to set times on "/tmp/ping.Kgw.mnt/linux-3.0/[...]/.dvb_demux.c.N7YlEM":
No such file or directory (2)
that was triggered by pingpong-rsync.bash.
|
|
Mounts two gocryptfs filesystems, "ping" and "pong" and moves the
linux-3.0 kernel tree back and forth between them.
When called as "pingpong-rsync.bash" it uses "rsync --remove-source-files"
for moving the files, otherwise plain "mv".
|
|
We (actually, go-fuse) used to call Chown() instead of Lchown()
which meant that the operation would fail on dangling symlinks.
Fix this by calling os.Lchown() ourself. Also add a test case
for this.
|
|
This file will also be used by other tests, so it should
have a generic name.
|
|
|
|
Most entries have already been implemented a while ago.
|
|
Running these tests from integration_tests' TestMain() was awkward
because they were run twice with unchanged settings.
integration_tests tests everything with OpenSSL and with native
Go crypto, but this does not take affect for the example filesystems.
To make this work, test_helpers is also split into its own package.
|
|
The plan is to drop support for the oldest filesystem versions
in gocryptfs v1.0. For now, we only warn the user.
|
|
In TestMain we call os.Exit as before, but inside actual tests
we now call t.Fatal().
|
|
Several fatal errors were just printed to stdout, which
meant they were invisible when running the test suite.
Fix this by introducing toggledlog.Fatal and convert as
follows:
Fatal errors -> toggledlog.Fatal
Warnings -> toggledlog.Warn
Password prompts -> fmt.Fprintf
|
|
It may not have been a "Wrong password" after all.
Also, push down disabling the warning so LoadConfFile() can
warn about things that matter.
|
|
This should make things saner and more extensible. It prepares
the infrastructure for "required feature flags" that will be used
to deprecate old gocryptfs version.
|
|
This field is added for the convenience of users and
may help them to identify which gocryptfs version
they need to mount a filesystem.
The same information is essentially contained in FeatureFlags,
but this is more difficult to decode for humans.
It is completely ignored programmatically (also by older gocryptfs
versions).
|
|
Just presenting an empty directory means that the user does not know
that things went wrong unless he checks the syslog or tries to delete
the directory.
It would be nice to report the error even if only some files were
invalid. However, go-fuse does not allow returning the valid
directory entries AND an error.
