A finding has been that the icon theme switch is not detected at runtime. It would be nice if we could add this, especially if customers explicitly test the support for high contrast modes.

@MathiasMagnus This change is to support Win32-OpenSSH by gpg-agent emulation of ssh-agent; You can use gpg-agent emulation of ssh-agent when you use Win32-OpenSSH. That is, you can use GPG auth subkey for Win32-OpenSSH.

@gniibe Am I misunderstanding something? I thought that with this change one is able to connect from a Windows box to a Linux box and have GPG agent forwarding work. I am still hitting pretty much the same issue described here: https://github.com/PowerShell/Win32-OpenSSH/issues/1564
On my Windows endpoint I'm running gpg.exe version 22.214.171.124237 and in C:\Users\mate\AppData\Roaming\gnupg\gpg-agent.conf I have a single line enable-win32-openssh-support. Running gpg-connect-agent.exe reloadagent /bye I have a gpg-agent running. Get-Process gpg-agent shows that it's running. In my Windows env I have SSH_AUTH_SOCK set to \\.\pipe\openssh-ssh-agent and my Linux endpoint is configured in SSH config with
ForwardAgent yes AddKeysToAgent yes RemoteForward /run/user/1015/gnupg/S.gpg-agent C\:/Users/mate/AppData/Local/gnupg/S.gpg-agent.extra
As the remote end reports /run/user/1015/gnupg/S.gpg-agent that socket for agent-socket when issuing gpgconf --list-dirs and my local gpgconfg.exe --list-dirs reports C%3a\Users\mate\AppData\Local\gnupg\S.gpg-agent.extra where I transform %3a to \: manually. SSH authentication works perfectly, when connecting pinentry-qt pops up to unlock my key and when connecting to yet another machine, my SSH agent is forwarded again. However, gpg fails to use my agent. Issuing gpg --list-secret-keys --verbose prints the following to the console:
gpg --list-secret-keys --verbose gpg: using pgp trust model getsockopt SO_ERROR failed connect_to C:/Users/mate/AppData/Local/gnupg/S.gpg-agent.extra port -2: failed. gpg: no running gpg-agent - starting '/usr/bin/gpg-agent' getsockopt SO_ERROR failed connect_to C:/Users/mate/AppData/Local/gnupg/S.gpg-agent.extra port -2: failed. gpg: waiting for the agent to come up ... (5s) getsockopt SO_ERROR failed connect_to C:/Users/mate/AppData/Local/gnupg/S.gpg-agent.extra port -2: failed. getsockopt SO_ERROR failed connect_to C:/Users/mate/AppData/Local/gnupg/S.gpg-agent.extra port -2: failed. getsockopt SO_ERROR failed connect_to C:/Users/mate/AppData/Local/gnupg/S.gpg-agent.extra port -2: failed. getsockopt SO_ERROR failed connect_to C:/Users/mate/AppData/Local/gnupg/S.gpg-agent.extra port -2: failed. getsockopt SO_ERROR failed connect_to C:/Users/mate/AppData/Local/gnupg/S.gpg-agent.extra port -2: failed. getsockopt SO_ERROR failed connect_to C:/Users/mate/AppData/Local/gnupg/S.gpg-agent.extra port -2: failed. gpg: waiting for the agent to come up ... (4s) gpg: waiting for the agent to come up ... (3s) gpg: waiting for the agent to come up ... (2s) gpg: waiting for the agent to come up ... (1s) gpg: can't connect to the agent: End of file
What is missing to tie the knot on both ends without having to resort to 3rd party tools like @rupor-github 's agent-gui? The remote gpg version is 2.2.19, is that the issue? Must that also be 2.3.9+?

Putting up for grabs and removing Kleopatra tag since for Kleopatra users this has been fixed (unless they manage to trigger multiple separate concurrent imports in Kleopatra).

@ikloecker You are right, I only thought of public key import. Then lets serialize this. Might even make for a nicer Progressbar if we count the outstanding files.
Dec 22 2022
Thanks all. It is a bug in Win32 OpenSSH. https://github.com/PowerShell/Win32-OpenSSH/issues/1953 it is already fixed. I think the issue will be resolved after the update is shipped. I could use ssh -T email@example.com as a workaround.
Well, not our bug... it's a kind of support question and answer:

I really don't want to bypass gpgme and then parse the import results and all other status output of gpgsm ourselves. I'll go for Andre's suggestion and serialize imports of multiple files.
This does not look like a problem in GnuPG/gpg4win because gnupg implements the ssh-agent protocol and not the ssh server or client functionality. ssh tells sshd whether it shall allocate a PTY (Pseudo TTY). I don't use ssh with github but it is likely that you may only run commands (which don't require a PTY). Usually you would invoke a "git" command cia ssh.
I meant bypass the gpgme engine and call gpgsm directly. Maybe using gpgme's spawn engine. But I am not sure whether this is really a good idea. If we can find a way to pass multiple filenames to gpgsm --server that would be better. But requires updates to gpgsm.
Authentication succeed if I pressed enter after:PTY allocation request failed on channel 0
I try WinGPG 4.1.0, and I receive an error:
PTY allocation request failed on channel 0
@werner Do I understand correctly that by "It might be easier to bypass the gpgsm and run gpgsm directly" you mean using gpgsm in server mode? Or what do you mean with "bypass gpgsm and run gpgsm" (which seems contradictory).
Dec 20 2022
With 100 concurrently running gpgsm processes they all try to get the lock for the keyring. And they need to do this several times and often also for the same certificate (fetched from an external resource to complete the chain). Not good. It might be easier to bypass the gpgsm and run gpgsm directly instead of adding a feature to gpgsm to directly import from many files.
Sure, we could do this. Shouldn't make the ImportCertificatesCommand much more complex than it already is.
Reopening this as there still seem to be ways to run into a deadlock as was reported in RT#13361. While I still think this points to some issue in gpgsm, when Testing this I found the behavior of Kleopatra to be wrong.

@raysatiro: Please re-open if you are able to give us a reproducer
Dec 6 2022
Not so fun fact: If you enter tcp://126.96.36.199:10001 (literally) as value for gpg-agent's log file, then on save gpgconf calls
gpg-connect-agent --homedir /home/ingo/dev/g10/.gnupghomes/utf16 --no-autostart RELOADAGENT
which hangs (probably trying to connect to the not existing IP address or to the blocked port). This also makes Kleopatra hang.

Windows accepts forward slashes in all API calls. Users are sometimes confused by this but this is a documented feature for ages in the API.
But what about real Windows filenames?
The log file is intended to be an URL. Thus forward slash is fine.
Support for multiple smart cards has been vastly improved in the last few years. I will tentatively close this as resolved because it's very likely that the problems have been resolved.
Looks like Kleopatra is writing the filename with the system's preferred directory separator. If GnuPG on Windows works if filenames are written with Unix directory separators, e.g. c:/foo/bla or //server/foo/bla, to the config files, then we can certainly change this in Kleopatra.

Merged PIPE connection part into master.
I updated *.m4 scripts in gogol:
Nov 2 2022
For *.m4 scripts, I pushed changes to prefer gpgrt-config with *.pc files than *-config scripts (T5034).
Before the change, it was not coherent; gpgrt-config gpg-error is preferred to gpg-error-config (if available), but libassuan-config was used if available.
After the change, gpgrt-config is used to configure gpg-error and libassuan, etc.

Will go into 2.3.9 and gpg4win 4.0.5
Is this still an issue or is the new gpgconf -X feature sufficient to detect this case?

There is a utility named kbxutil which can be sued to dump the pubring.kbx file without any post-processing by gpg. I would check whether there are any other keys after the VideoLAN key. iirc, kbxutil ist not commonly installed; you may need to build the software yourself or copy the pubring.kbx to Linux and check it here.

@aheinecke Please show me how you configure your libassuan-master (and the output which detects host's gpg-error-config erroneously).
Oct 25 2022
I have pushed the patch, but still it did not work for me properly over everything and I had to add --enable-install-gpg-error-config to libgpg-error. This was because of at least the 64 bit build of libassuan-master it picked up gpg-error-config from my host system. I then tried to add --with-gpg-error-prefix to the assuan call but that failed because it only looked for gpg-error-config in this prefix and not for any gpgrt-config and failed immediately with a command not found error.

Cool, I will try it out ASAP. You must have read my mind. Only yesterday evening I ran into problems because the current code in src/Makefile.am to symlink the static libs did not work on my new dev system with a lib64 layout and thought that I needed just a patch like this to fix it properly.
Ah, sorry, I did my own changes before looking T6244#164317
Pushed the changes to 2.2 and master.
Thank you for your report. The issue is handling of static linking in GnuPG.
