In select_application function, we can minimize the holding W-lock.

This may requires major changes for scdaemon.

For the cancelling operation, each card reader access should have an independent resource manager context.
Currently, a single pcsc.contex is shared by all reader accesses.

Hard lockup should be avoided. In particular, following conditions should meet:

• gpgconf --kill scdaemon can kill scdaemon
• KEYINFO requests can be answered for other connections of scdaemon

As of 2024-11-18, my hypothesis is:

• there are some sort of race conditions between PC/SC + card reader (or its driver) + smartcard + scdaemon on Windows, at least at initial use after boot
• because of this, SCardConnect of PC/SC call wrongly fails (somehow confirmed by @ebo's experiments + @gniibe's speculation), or wrongly never returns (@gniibe's guess, side info: its slowness is observed in T7400).

@ebo Thank you for your testing.

@ikloecker indeed we try only for 5 seconds:

I think that the card reader is not connected and there is no Scardsvr at this time.
And the card reader connection to USB port results invoking Scardsvr. Then, "SCD SERIALNO --all" gets success.

For T6567 I changed the way that Kleopatra runs "gpgconf --launch gpg-agent". This change is not yet in Eva's test build. It seems my change is not good because running "gpgconf --launch gpg-agent" timed out after 5 seconds in 3 of 3 tests starting Kleopatra after a reboot of the VM. To check if "gpgconf --launch gpg-agent" really takes that long I measured the time in PowerShell after another reboot of the VM. The result is shocking.

Please note that a card insertion to a card reader and a card reader connection to PC are different things.
It may cause different results.

I put "scd" tag and let me claim this ticket.

The symptom of this bug was:

• there are multiple waiters for COND.
• COND is fired by npth_cond_broadcast, all waiters should be waken up, but only one wakes up by the old code of 1.7.
• other waiters keep waiting forever.

After I fixed the problem, I realized that the description of this ticket was not accurate, so, modified.

gpg4win 4 has been released with unicode support. Closing.

with gpg4win-Beta-50: "Rückstellcode" is shown correctly with an ü

This works now.

Well for 3.3 we will have full support for high contrast with the correct icons on all platforms, additionally we detect and support dark mode on all Windows 10 Versions > 1709 So this can be resolved. (Both for Qt5 and 6). What I have not yet checked if Qt6::systemInfo::colorScheme reports the correct one under windows 11 desert theme, but as you mention that is also part of a different issue where when then also should clean up the kleo systeminfo etc. if this is reliably supplied as information by qt.

Setting this to testing. Could be tested as described in https://dev.gnupg.org/T7188#188093 by verifying that the logged debug messages also use correct encoding.

Okay. Done in gpgme for gpgrt >= 1.51 (T7188).

Sounds like a good idea.

@werner Would it be okay to call gettext_use_utf8 (3) in gpgme's do_subsystem_inits where we currently call gettext_use_utf8 (1)? See https://dev.gnupg.org/source/gpgme/browse/master/src/version.c$77

Alright: Call gettext_use_utf8 (3) to set the current thread to utf8 and init all new threads to utf8 as well. This function with that value (actually bit 1 is relevant) can be used several times but it will never switch back the initialization to utf8. However, switching back and force to utf8 per threads is still possible.

KWin has a script called "Dim screen for Administrator Mode" which mimics the windows behavior.

This should be tested as part of testing T5960 by checking that the German error description "Falscher Rückstellcode" is shown after entering a wrong reset code (PUK) for an OpenPGP smart card (https://dev.gnupg.org/T5960#188013).

Using/setting a value of 2 would work for Kleopatra.

That is probably right for gpgme as used by kleopatra. However in gnupg we need to switch utf8 on and off.

This also works for VSD 3.3 (because the required changes/patches are in gpg4win).
