Gopass: `gopass -c <entry>` fails to copy to the system clipboard

[sudoforge]

Summary

Since commit af62f1b4f099447488f8da6c90304d3e9c456764, the standard gopass -c <entry> invocation has failed to copy to the system clipboard:

➜ gopass -c passwd
Incorrect Usage. flag provided but not defined: -c
<snip helptext>
2020/05/03 10:35:05 flag provided but not defined: -c

Steps To Reproduce

Create the following file in /tmp (replace <ENTRY> with the path of a valid entry in your root password store):

$ cat /tmp/gopass-bisect-test
#!/usr/bin/env sh

set -e

go build -a
./gopass -c <ENTRY> &> /dev/null

Clone the repository, and run:

$ git bisect start HEAD 49a3bad9d7ec68d8616e269876f72f09f24dfb83
$ git bisect run /tmp/gopass-bisect-test
$ git bisect reset

_49a3bad9d7ec68d8616e269876f72f09f24dfb83 is a known good commit that supports go modules; feel free to adjust this as desired._

You can also test this manually if you'd prefer:

# Check out the commit just before the problematic commit
# This works successfully
$ git checkout af62f1b4f099447488f8da6c90304d3e9c456764~1
$ go build -a
$ ./gopass -c <ENTRY>

# Now check out the bad commit
# This fails as expected
$ git checkout af62f1b4f099447488f8da6c90304d3e9c456764
$ go build -a
$ ./gopass -c <ENTRY>

Expected behavior

The first line of the entry should be copied to the system clipboard.

Environment

• OS: Arch Linux
• Kernel version: 5.6.4
• Installation method: From source: go build

gopass version output:

➜ ./gopass version
gopass 1.9.0-git+HEAD go1.14.2 linux amd64
<root>     - gpg 2.2.20 - git 2.26.2 -   fs 0.1.0
Available Crypto Backends: gpgcli, plain, xc
Available RCS Backends: gitcli, noop
Available Storage Backends: fs, inmem

Additional context

• This is a regression, as the tree tagged at v1.8.6 works as expected -- this is the last version of gopass that I had installed prior to v1.9.0, which is the first release that includes this regression.

• Note that --clip works as expected.

Thanks again for the report @sudoforge,

I can confirm that the issue with flag provided but not defined: -c still happens with be8e8d698c547ede6dff093719b2017e4f415eb2.

Also I can confirm that --clip works after be8e8d698c547ede6dff093719b2017e4f415eb2, but not with v1.9.0.

[sudoforge]

Also I can confirm that --clip works after be8e8d6, but not with v1.9.0.

Good catch!

Given that this shows up when bumping the version of urfave/cli, it's possible that this is an upstream issue, but in searching the board there, I didn't see anything that stood out -- given that it _may_ be a regression caused by this project's usage, I'll defer to your team to handle creating or linking to an upstream issue.

[dominikschulz]

Ah, ok. This might indeed be related to the urfave/cli major version bump.
I only tested -c on the show (and other) subcommand. Not on the short invocation.

[dominikschulz]

Ok, that was an easy one. Actually it's not an regression in urfave/cli but something that's properly documented in their migration docs.

I simply missed the implicit default show action because it's defined not where all the other subcommands are set up.

[BasilSkrnk]

The very same issue for me, Arch Linux 5.6.8.

[sudoforge]

The very same issue for me, Arch Linux 5.6.8.

@dominikschulz has submitted a patch in #1319 as you can see from the link that was added -- I will be keeping the package maintainer apprised of this patch landing in master; they have already been informed of this issue and are ready to backport the patch.

[BasilSkrnk]

The issue was solved with the version gopass-1.9.0-2, I use the one from the Arch Linux repos, haven’t compiled from the source.

Now gopass shows my passwords to the stdout (as if I typed --clip), which wasn't present before, but seems like this change in logic isn‘t a bug and is not relevant to this issue.

[nikaro]

For me it still does not clip when i use -c/--clip. But with -C/--alsoclip it works.

[Pharb]

@nikaro Which version of gopass are you using? What operating system are you using?

[sudoforge]

@nikaro If you are using community/gopass-1.9.0-2, have xclip or another supported clipboard manager installed, and are experiencing the issue I described in my original post, then you may be experiencing another issue altogether. Please explore this further and open a new issue, if warranted, so the developers can track it appropriately.

@BasilSkrnk Yeah, I noticed that too. It's actually printing out the entire contents of the file, as if calling gopass show <entry>; this is probably a bug, although I don't believe this is related to the issue I reported here, and am unsure offhand if it is related to the patch.

[nikaro]

@sudoforge i'm using community/gopass-1.9.0-2 and have xclip installed. I'll try to invetigate and open an new issue.
