Oops. I closed the task accidentally.

Fixed (for GnuPG 2.4). I hope 2.2 prints the same status messages.

The General Error happens also when the PIN is blocked and no Pinentry opens.
As in this case, where the indicated "Generate New Keys" button was used on a blocked card.

Trying to reach Ralph Seichter via the eMail address he is using failed – Osterferien?

strcasecmp is pretty standard on Unix. However, in GnuPG we test for it and mostly use our own ascii_strcasecmp to avoid fun with locales. Ralph Seichter is providing macOS builds for GnuPG (https://sourceforge.net/p/gpgosx/docu/Download/) . Maybe it is worth to contact him via the gnugp-devel mailing list and ask him whether he has experience with your toochain.

By adding "-Wl,-t" to the arguments g++ reported:

Libtool invocation has "--tag=CXX --mode=link /opt/local/bin/g++-mp-7 -std=c++11 -pipe -Os -std=c++17 -D_GLIBCXX_USE_CXX11_ABI=0", but g++ then has no -lstdc++ – in C -lc is automatically used because there all C library functions can be taken from… (same for mathematical functions and -lm)

It seems libtool fails to add the standard C and C++ libraries to the link command line. On Linux I have "[...] -lstdc++ -lm -lc [...]" in the libtool link command line. Looks like a bug in the tooling (macports or libtool).

Thanks, that patch works for me.

We have discussed this yesterday. The idea/plan is to release the core library and the bindings as separate tarballs (created from the same repo) in the future.

This can be tested with Kleopatra by configuring an invalid keyserver and then updating an OpenPGP certificate.

In 2.4 we have rG1383aa475 which does

Pushed the change in: rGf50c543326c2: agent: Allow simple KEYINFO command when restricted.

No, thank you both for the speedy responses :)

Thanks a lot for your quick testing.
The commit rGff42ed0d69bb: gpg: Enhance agent_probe_secret_key to return bigger value. of GnuPG 2.2 introduced this bug.

Ah, thanks Werner, I'll keep that in mind.

Although I don't think this is the case here one should be aware that tests mail fail due to global configuration of GnuPG (/etc/gnupg/*.conf). There is no easy way so solve this except for running a per-test local installation of GnuPG using the gpgconf.ctl feature.

You can get more information by applying a patch below (and also tests/json/Makefile.in):

T4820 is not related (it's a failure of t-keylist-secret in t-json), while this is failure of t-decrypt.

Arghh, a GPGME_DEBUG=3 which shows basic I/O preparation does not exhibit the bug.

Fixing gpg is easy but there is some bug lingering in gpgme which might be a recent regression. An strace shows

gpg --list-packets shows this:

Uploaded the corrupted file.

Can you make this corrupted file available to us?

Hello,
So after testing on gpgme-1.17.1, with run-verify under tests as you mentioned, with corrupted file it hangs forever.
Now we can say it's a bug in gpgme_op_verify.

We provide the examples for a reason. Actually, two reasons: To test our changes ourselves. And to provide working examples for others. If your code doesn't work then you'll have to figure out where the example and your code differ. If the example doesn't work then we'll have a look.

@Karam, please test as suggested by @ikloecker.
