Use error wrapping in Go 1.13

[ianlewis]

Make use of the new error wrapping functionality and API to be able to check error types easier.

@ianlewis I want to try this issue. But I don't know where to start because this issue is related to all sorts of codes in this project. And I'm not familiar to the details of gVisor but I know what this issue expects. Could you guide me in a bit?

[ianlewis]

@Yuya9786 It shouldn't be too involved. This is really just a placeholder issue to use "%w" style formatting directives rather than "%v" for errors when calling fmt.Errorf. So rather than this:

return fmt.Errorf("some error: %v", err)

The code would look like this

return fmt.Errorf("some error: %w", err)

You can search for some places where fmt.Errorf is used here: https://github.com/google/gvisor/search?q=fmt.Errorf

[Yuya9786]

I got it. I'll fix all fmt.Errorfs' "%v" to "%w" .

@Yuya9786 Excuse me, are you still working on this issue?
If not, may I would like to take over this?

[Yuya9786]

@ryo-yamaoka I've already done to fix and succeeded to build, but I couldn't succeed to test because of timeout.
Maybe the cause is that my laptop specs are not good enough.
Would you be willing to test instead of me?

[ryo-yamaoka]

@Yuya9786 I tried high spec machine, then succeeded to build and unit-tests, and failed nogo-tests into make tests.
The reason for the failure seems to be different (There appears to be no timeout log.), but the bazel logs disappeared and I couldn't see them...
Is it also nogo-tests that you failed?

By the way, when I run make nogo-tests I get a lot of errors like the following.
You may want to fix this first.

[Yuya9786]

@ryo-yamaoka Thank you for pointing out my mistakes, I fixed these.
I tried to test (make unit-tests and make tests) again,
and then unit-tests was succeeded but whole tests wasn't as well you.
But I can see these failed test.log like following.

exec ${PAGER:-/usr/bin/less} "$0" || exit 1
Executing tests from //pkg/sentry/fdimport:fdimport_nogo
-----------------------------------------------------------------------------
printf: pkg/sentry/socket/netstack/stack.go:470:10: fmt.Errorf format %w has arg err of wrong type gvisor.dev/gvisor/pkg/tcpip.Error

exec ${PAGER:-/usr/bin/less} "$0" || exit 1
Executing tests from //pkg/sentry/control:control_nogo
-----------------------------------------------------------------------------
printf: pkg/sentry/socket/netstack/stack.go:470:10: fmt.Errorf format %w has arg err of wrong type gvisor.dev/gvisor/pkg/tcpip.Error

There are many errors because of same reason.
tcpip.Error is different from standard error and doesn't have Error() function.
I think That's why these error occur.
But I'm not sure very well because I'm not familiar to Golang's detail.
So could you check it?

I posted same content in my pull request. (#7285 (comment))

[Yuya9786]

I fixed it and then succeeded unit-tests and nogo-tests.
But I didn't succeed container-tests and syscall-tests because of timeout.

[ryo-yamaoka]

Okay thanks, I'll check tonight

[ryo-yamaoka]

@Yuya9786 Me too test failed, but not timeout error.
I don't know why occurred this errors...

For now, your PR's CI failed by simple issue.
The code you fixed is looks no problem.
I think that CI will pass by fix this, so I think it is a good idea to try that first.

[Yuya9786]

@ryo-yamaoka Thank you for your help.
I haven't yet figured out the cause of this error too.

[noopta]

Is this issue still active? I'd like to try taking on this as my first issue

[milantracy]

it seems that @Yuya9786 had a PR which was ready to be merged, while there are some conflicts with the master branch.

You may confirm with the author to see if it will be updated.

[Yuya9786]

I think my PR was approved by two reviewers and I resolved the conflicts once, but it's not been merged.
So honestly I don't know what to do

[milantracy]

hey @Yuya9786 thanks for the pr, it seems that there are still some conflicts that block the merge, e.g. VFS1 was completed removed at pkg/sentry/fs which your change are also applied to.

Could you rebase your change and resolve those conflicts? Then we shall be able to merge the pull request.
