Kleopatra running on Linux (Ubuntu 20.10, 21.04; Fedora 34, 35 (rawhide)) does this. Closing Kleopatras window saves columns and column widths as shown (it even works if I change the systemwide used font).
On Windows 10 this does not work. Closing Kleopatra via the windows "Close Button" or by selecting "Close Window" or "Exit" from the main menu settings will not be saved. Opening the window again will show columns as they where after installing (way to small for displaying the dates created and expired and the hash of the key). The sorting column is lost too on Windows, but not Linux.
I am unsure if this bug is triggered by my company setup, or if it exists on any Windows 10 installation.

Looks like its missing an include

@dkg for sure, I will test out the patch ASAP. Thanks for the ping.

I think you're saying "GnuPG will reject all subpackets marked with a critical flag unless there is a specific known semantic for *criticality* for that subpacket" Am I understanding that right? Is there a published list of criticality semantics that GnuPG is willing to accept? How do those semantics differ from standard semantics for the packet in question?

fwiw, i think a patch like this ought to work with reasonably-modern versions of autotools:

@wltjr maybe you could take a look at this?

werner this would really be a bug because we have code in Kleopatra to both save the selected coloumns, their widths and the sorting state.

The mix up of external patches and commits makes it not easy to see what has been fixed. AFAICS rC3d095206c30d fixes the last bug mentioned by @ballapete on Jan 26.

When building with no threads support, I think that generating same lock-obj-pub-$host.h is just possible by this change.

Tell us the architecture(s) which doesn't support POSIX threads by uClibc.
Adding support for such an architecture would be the best.

Sorry, I was assuming uClibc were not supporting POSIX threads.

Thank you for more information.

I was not the author of the host "hacking" which has been committed to buildroot in 2016 by https://git.buildroot.net/buildroot/commit/package/?id=2f89476ad98b82ea9f914337b0050c4808082c82 so I can't really comment on it.
You can find more information here: https://patchwork.ozlabs.org/project/buildroot/patch/1451762923-15985-1-git-send-email-joerg.krause@embedded.rocks/
Especially, it seems that Jörg Krause started a discussion about this issue and proposed a patch to fix the architecture depends but it was never applied. Unfortunately, I wasn't able to find more information as it seems that links on comments.gmane.org are broken ...

Please note that the result with --host="arm-unknown-linux-gnueabi" for linux-uclibcgnueabih machine is different to the one of correctly generated version by gen-posix-lock-obj.c with USE_POSIX_THREADS undefined on the host.

I would understand your workaorund of using artifical --host intentionally.

Merged your fix. Thanks for the contribution. Commit should show up here in a second.

This won't work in the context of buildroot as we're passing --host="arm-unknown-linux-gnueabi" to avoid the following build failure:

With GnuPG in master (to be 2.3), it can handle the second SKESK when the first one fails.

Thank you for the report. I had expected *-*-linux* matches only to GNU/Linux (Linux kernel with GNU C library).

I have a fix in a branch here: https://github.com/drichardson/gpg4win/tree/fix-missing-zh-readme

They are mandatory for gnupg but not for Libgcrypt and Libgpg-error. I guess we can fix that.

A page feed character is a very common and useful control character. In fact Emacs knows how to jump page by page.

Somewhat related: before the change that resulted in the PIN issue, I already occasionally had to reconnect the reader because gnupg would ask for the card when it was in fact already present.

Because, threads are optional on uclibc as threads are not supported by all embedded targets.
libgpg-error was building perfectly fine without threads until version 1.40 as all pthread calls were protected by USE_POSIX_THREADS.
Should I understand from your answer that threads are now mandatory?

A beta release is available as https://gnupg.org/ftp/gcrypt/alpha/libgcrypt/libgcrypt-1.9.2-beta16.tar.bz2 (https://gnupg.org/ftp/gcrypt/alpha/libgcrypt/libgcrypt-1.9.2-beta16.tar.bz2.sig).

How does it come that you have a Linux kernel without threads? Or maybe the better question is why does libc not support threads?

Good morning.

The now used /var/run thingy solves all these problems nicely. In fact we may eventually remove the use fallback of using sockets in the GNUPGHOMEDIR.

Eventually we will move to keyboxd which is already an experimental option in 2.3. Thus we won't do anything here.

The other patches don't make sense because of future plans for dirmngr.

Critical attributes are well known from CMS and X.509 and some have a history which can only be described as cargo cult. We should not allow them in the OpenPGP ecosystem without giving them a specific semantic aside from "we do something with it".

Done. FWIW. in 2.3 symcryptrun will be removed entirely.

RFC 4880 says:

POSIX says so (use printf instead).
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html

Without any defined semantic it is not proper to ignore a critical bit. The software which created this keyblock seems to aim for incompatibility.

iirc the advise from the GNU coding standards is to use printf(1) instead of trying to figure out how echo(1) works.

Thank you. I'll fix. Perhaps, I'll ignore old UNIXen like AIX 6.1, which has no way to echo with no newlines.

The problem ist not an "ugly error message" but it does not recognize that the e-mail IS encyrpted by Symantec-PGP! But the plugin always says:

Actually I would be in favor of removing this portable thingy. It is and will always be the worst and most insecure way of using crypto.

Looks like this has been addressed in af23ab5c5482d625ff52e60606cf044e2b0106c8. A quick test building the current version in master with --disable-asm worked for me.

Unfortunately, building without "--disable-asm" does not work if building a universal package under MacPorts (e.g. 32bit and 64bit x86 or 64bit x86 and arm64).

to explain a bit more: This report was opened after the reported defect was already fixed.
As we are getting many reports and technical suggestions, please keep the reports focused on one point only if possible
and open general discussion points about development improvements on gnupg-devel@.

For what it is worth we have also just tasked someone from our team to reinstate our buildbot / CI but this would likely not have helped in the current case of the libgcrypt buffer error as only ASAN with large hashtests would have found this. Still we have the general infrastructure for such tests we are just lacking resources. That is why we publish everything and encourage the community to at least help us with testing.

the issue regarding this self test was immediately found after release. Our development is completely open and everyone is free to run tests with our software on any platform at any time. We would respect and fix all those bug reports. None about this reached us during the development phase.
As this is not happening as it should during development we release and test on our platforms and build systems. When after the release others test, too we immediately fix the issues as happened with 1.9.1 in libgcrypt.

A public keyblock without a user id packet is non-compliant. I see no reason to provide a feature to created crippled data. We had all this discussions back in the early 90s regarding to self-signatures. OpenPGP spoke a final word on this in 1998 by making user ids and corresponding self-signatures mandatory.

Not exactly the answer I was hoping for..

Oops, that was an experimental feature never intended for a released version. Will be removed in a way that it does not leas to compile problems - just to be extra cautiousness.

Thanks for the feedback. I sadly forgot to include the italian translations of GpgOL in the installer. So they will only be part of the next relase.

no, that doesn't change anything.

Does it build if configure with parameter 'ac_cv_sys_symbol_underscore=yes'? <path-to-libgcrypt-source>/configure ac_cv_sys_symbol_underscore=yes --host=aarch64-apple-darwin ...

Compiling now works, but I get the following linker errors:

@jukivili Thanks for the reply! We've reverted that commit downstream in Gentoo as a temporary workaround, as due to some complications, our release systems needed to build without asm (for now) to ensure portability. Rest assured, this is not the default, and is discouraged for regular users.

Problem solved in Gpg4win 3.1.15 version! I think it can be closed!

Latext 1.9.1 builds without any unreported workarounds. Done. Close.
