lang/cpp/src/gpggencardkeyinteractor.h (class GpgGenCardKeyInteractor):
Add enum Curve. Add member function setCurve.
lang/cpp/src/gpggencardkeyinteractor.cpp
(class GpgGenCardKeyInteractor::Private): Initialize simple members
in-class. Add member curve.
(GpgGenCardKeyInteractor::~GpgGenCardKeyInteractor): Use default d'tor.
(GpgGenCardKeyInteractor::setCurve): New.
(GpgGenCardKeyInteractor::action): Return curve defaulting to
Curve25519.
--
This enables users of this interactor to request the generation of
ECC keys with a specific curve as smart card keys. It's up to the user
to specify a curve that is actually supported by the smart card.
GnuPG-bug-id: 4429
* lang/qt/src/qgpgmenewcryptoconfig.cpp (struct Select1St): Remove.
--
This struct was never used in this implementation of the crypto config
classes and it causes a build error with Qt 6 where QPair is an alias
for std::pair.
* configure.ac: Look for Qt 5 and/or Qt 6. Require C++17 if Qt 6 binding
is built. Build cmake files QGpgmeConfig* for Qt 5 and QGpgmeQt6Config*
for Qt 6.
(available_languages): Add "qt5" and "qt6".
(WANT_QT5, WANT_QT6): New conditionals.
* lang/qt/src/Makefile.am: Keep building libqgpgme for Qt 5. Build
libqgpgmeqt6 for Qt 6.
* lang/qt/tests/Makefile.am: Build tests for Qt 5 or Qt 6.
* lang/qt/src/QGpgmeQt6Config-w32.cmake.in.in,
lang/qt/src/QGpgmeQt6Config.cmake.in.in,
lang/qt/src/QGpgmeQt6ConfigVersion.cmake.in, m4/qt6.m4: New.
--
This makes it possible to build QGpgME optionally for Qt 6.4.0 or later.
By default or if the language "qt" is enabled, then QGpgME is built
either for Qt 5 (if found) or Qt 6. A build for Qt 5 or Qt 6 can be
requested by explicitly enabling the language "qt5" or "qt6". Building
QGpgME for Qt 5 and Qt 6 simultaneously is not supported.
m4/qt.m4: Rename to
m4/qt5.m4: this.
(FIND_QT): Rename to FIND_QT5.
(GPGME_QT): Change variable prefix to GPGME_QT5.
(GPGME_QTTEST: Change variable prefix to GPGME_QT5TEST.
configure.ac, lang/qt/src/Makefile.am, lang/qt/tests/Makefile.am:
Adjust accordingly.
--
In preparation to adding support for building qgpgme for Qt6, add the
version number to a few variables to avoid confusion.
* lang/cpp/src/gpgsignkeyeditinteractor.cpp (enum SignKeyState): Add
new state REJECT_SIGN_EXPIRED.
(makeTable): Add entries for new state to transition map.
(GpgSignKeyEditInteractor::action): Handle new state.
--
With this change the edit interactor aborts the key signing operation
with a "key expired" error instead of with a "general error".
GnuPG-bug-id: 6155
* lang/qt/src/qgpgmerefreshsmimekeysjob.cpp
(QGpgMERefreshSMIMEKeysJob::start): Replace 'auto' in lambda with the
actual type.
* lang/qt/src/qgpgmesignkeyjob.cpp (class TrustSignatureProperties): Add
default c'tor and c'tor initializing all members.
* lang/qt/src/util.cpp (toFingerprints): Replace 'auto' in lambda with
the actual type.
* lang/qt/tests/run-exportjob.cpp (createExportJob): Replace 'auto'
return type with actual type.
--
This fixes compilation with strict C++11.
GnuPG-bug-id: 6141
* lang/cpp/src/importresult.cpp (ImportResult::mergeWith): Replace
'auto' in lambdas with the actual type.
--
Generic lambdas require C++14.
GnuPG-bug-id: 6141
* lang/qt/tests/t-addexistingsubkey.cpp
(AddExistingSubkeyJobTest::testAddExistingSubkeyWithExpiration): Handle
negative expiration date.
--
On 32-bit systems the expiration date of the test key overflows. This
will cause the AddExistingSubkeyJob to fail. We expect it to fail with
an "invalid time" error.
GnuPG-bug-id: 6137
* lang/cpp/src/gpgaddexistingsubkeyeditinteractor.cpp
(GpgAddExistingSubkeyEditInteractor::Private::nextState): Fix inverted
logic of string comparisons.
--
This fixes the problem that the interactor didn't return the proper
error code if gpg didn't accept the key grip or the expiration date.
GnuPG-bug-id: 6137
* lang/qt/tests/t-addexistingsubkey.cpp,
lang/qt/tests/t-changeexpiryjob.cpp: Convert expiration time to
uint_least32_t.
--
This doesn't change the outcome of the tests (they also pass without
this change because of the expiration dates of the test keys), but it's
still good practise to treat the expiration time as an unsigned number
if the assertions check that the expiration time is in some range.
GnuPG-bug-id: 6137
* lang/qt/src/qgpgmeaddexistingsubkeyjob.cpp (add_subkey): Convert
expiration time to uint_least32_t.
--
This fixes the corresponding test on 32-bit systems where time_t (the
return type of expirationTime()) is a signed 32-bit integer type.
GnuPG-bug-id: 6137
* lang/qt/src/cryptoconfig.cpp (CryptoConfig::entry): Add nullptr
checks.
--
This fixes a crash when gpgconf is not found. When every return
value is NULL.
GnuPG-Bug-Id: T6131
* lang/python/src/core.py (Context, Data): Don't call __del__
from __exit__ method, as the object may be still in use.

* lang/qt/src/Makefile.am, lang/qt/src/job.cpp: Update accordingly.
* lang/qt/src/protocol.h (class Protocol): Remove pure virtual member
function refreshOpenPGPKeysJob.
* lang/qt/src/protocol_p.h (Protocol::refreshOpenPGPKeysJob): Remove.
* lang/qt/tests/run-refreshkeysjob.cpp (main): Use ReceiveKeysJob for
OpenPGP keys.
--
The RefreshOpenPGPKeysJob did more than it was intended to do, e.g. it
imported new keys with the email addresses of the key to be refreshed
via the configured auto-key-locate methods, but only a refresh from the
key servers is wanted. For this we can use the ReceiveKeysJob.
This commit mostly reverts the commits
e12861f18cc64a8daf50
The changes are source- and binary-compatible to the last release.
GnuPG-bug-id: 5951
* lang/qt/src/Makefile.am (qgpgme_sources): Add signencryptjob.cpp.

* lang/qt/src/signencryptjob.h (class SignEncryptJob): Add member
functions setFileName, fileName.
* lang/qt/src/qgpgmesignencryptjob.cpp (sign_encrypt): Set file name of
input.
(sign_encrypt_qba, QGpgMESignEncryptJob::exec,
QGpgMESignEncryptJob::start): Pass file name to sign_encrypt resp.
sign_encrypt_qba.
--
This makes it possible to store the original name of a signed and
encrypted file in the resulting data.
GnuPG-bug-id: 6056
* lang/qt/src/Makefile.am (qgpgme_sources): Add encryptjob.cpp.
* lang/qt/src/encryptjob.cpp: New.

setFileName, fileName.
* lang/qt/src/qgpgmeencryptjob.cpp (encrypt): Set file name of input.
(encrypt_qba, QGpgMEEncryptJob::exec, QGpgMEEncryptJob::start): Pass
file name to encrypt resp. encrypt_qba.

This makes it possible to store the original name of an encrypted file
in the encryption result.

* lang/qt/src/downloadjob.h, lang/qt/src/exportjob.h,
lang/qt/src/keylistjob.h lang/qt/src/refreshkeysjob.h: in qt6 we need

--
It fixes some compile qt6 compile error.

* lang/cpp/src/GpgmeppConfig-w32.cmake.in.in,
lang/cpp/src/GpgmeppConfig.cmake.in.in: Remove find_package() call.
--
The KF5 variants have been removed years ago with revision
a3cf30f894.
* lang/qt/tests/t-various.cpp (TestVarious::testSignKeyWithExpiration):
Assert that the expiration date is either 2106-02-05 or 2106-02-04.
--
This avoids a test failure if the test is run at 00:xx:xx in a location
that uses DST.
GnuPG-bug-id: 5991
* lang/qt/src/qgpgmesignkeyjob.cpp (sign_key): Change maxAllowedDate to
2106-02-05. Change log-level from warning to debug.
* lang/qt/tests/t-various.cpp (TestVarious::testSignKeyWithExpiration):
Remove check for warning. Adapt assertion.
--
Capping the expiration date at 2106-02-05 prevents a u32 overflow when
adding the number of days until the maximal date to the current time.
GnuPG-bug-id: 5991
* lang/cpp/src/key.cpp (ostream operator<< for Subkey): Fix wrong output
of isInvalid and isDisabled flags. Add output of key grip, card serial
number and the flags isSecret, isQualified, isDeVs, and isCardKey.
--
This makes it easier to check those properties for different keys, e.g.
with the run-keylist test program.
GnuPG-bug-id: 5965
* lang/cpp/tests/run-keylist.cpp (main): Handle --with-secret option.
Print error for unknown option.
--
The --with-secret option was already listed in the help. Now it also
works.
GnuPG-bug-id: 5965
* lang/qt/src/refreshkeysjob.h (RefreshKeysJob::result): Remove optional
parameters auditLogAsHtml and auditLogError.
* lang/qt/tests/run-refreshkeysjob.cpp (main): Update accordingly.
--
This reverts f4c3560925. The reason for
the previous change does no longer apply.
GnuPG-bug-id: 5951
* lang/qt/src/refreshopenpgpkeysjob.h: New.
* lang/qt/src/Makefile.am, lang/qt/src/job.cpp: Update accordingly.
* lang/qt/src/qgpgmerefreshopenpgpkeysjob.h (class
QGpgMERefreshOpenPGPKeysJob): Derive from RefreshOpenPGPKeysJob with
result ImportResult. Remove unused start overload.
* lang/qt/src/qgpgmerefreshopenpgpkeysjob.cpp (locate_external_keys):
Ignore result of KeyListJob. Return import result.
(receive_keys): Return import result.
(refresh_keys): Merge the two import results and return the result.
* lang/qt/src/protocol.h (class Protocol): Add pure virtual member
function refreshOpenPGPKeysJob.
* lang/qt/src/protocol_p.h (Protocol::refreshKeysJob): Return nullptr
for OpenPGP protocol.
(Protocol::refreshOpenPGPKeysJob): New.
* lang/qt/tests/run-refreshkeysjob.cpp (main): Use appropriate job
for the protocol of the key to refresh.
--
This adds RefreshOpenPGPKeysJob complementing RefreshKeysJob (for S/MIME
keys). Changing the result type of RefreshKeysJob would break the ABI.
Therefore we have to introduce a new base class for the refresh job for
OpenPGP. We derive this base class from AbstractImportJob because we
want to return an import result.
GnuPG-bug-id: 5951
* lang/cpp/src/context_p.h (enum Context::Private::Operation): Add
value KeyListWithImport.
* lang/cpp/src/context.cpp (Context::startKeyListing, Context::nextKey):
Set lastop to KeyListWithImport if keylist mode includes Locate.
--
Adding Import to lastop for keylist operations that perform a locate
allows retrieving the import result with Context::importResult.
GnuPG-bug-id: 5951
* lang/cpp/src/importresult.h, lang/cpp/src/importresult.cpp (class
ImportResult): Add member function mergeWith.
--
This allows creating a consolidated result of several independent
imports. If the import results to merge considered the same keys, then
not all counts can be consolidated correctly, but the important numbers
like the number of considered keys, the number of imported keys, the
number of unchanged keys and the numbers of new user IDs, subkeys,
signatures and revocations should be correct.
GnuPG-bug-id: 5951
* lang/qt/src/protocol_p.h (Protocol::locateKeysJob): Use Locate alias
instead of Extern|Local.
* lang/qt/src/qgpgmekeyformailboxjob.cpp (do_work): Ditto.
--
* lang/qt/src/qgpgmerefreshopenpgpkeysjob.h,
lang/qt/src/qgpgmerefreshopenpgpkeysjob.cpp: New.
* lang/qt/src/Makefile.am: Add new files.
* lang/qt/src/protocol_p.h (Protocol::refreshKeysJob): Add support for
OpenPGP protocol.
--
The new job performs a --locate-external-keys for the email addresses
of all not revoked user IDs of the given keys, and it performs a
--recv-keys for the fingerprints of the given keys. The former may
import new keys from WKD or an LDAP server or via some other
(hopefully trusted) auto-key-locate mechanism.
GnuPG-bug-id: 5951
* lang/cpp/src/context.h, lang/cpp/src/context.cpp (class Context):
Add nested class KeyListModeSaver.
--
This RAII-style class can be used to save the currently used key list
mode in case it needs to be changed temporarily. On destruction, it
will restore the key list mode that was active at construction time.
GnuPG-bug-id: 5951
* lang/qt/src/qgpgmerefreshsmimekeysjob.h,
lang/qt/src/qgpgmerefreshsmimekeysjob.cpp
(QGpgMERefreshSMIMEKeysJob::slotStderr): Remove.
* lang/qt/src/qgpgmerefreshsmimekeysjob.cpp
(QGpgMERefreshSMIMEKeysJob::startAProcess): Handle
readyReadStandardOutput and readyReadStandardError signals with lambdas.
--
For now output stdout and stderr of gpgsm process as debug log. In
particular, this "adds" the missing slot slotStdout.
GnuPG-bug-id: 5951
* lang/qt/src/refreshkeysjob.h (RefreshKeysJob::result): Add optional
parameters auditLogAsHtml and auditLogError.
--
This is necessary for the OpenPGP-implementation of this job.
GnuPG-bug-id: 5951
* lang/qt/src/refreshkeysjob.h (class RefreshKeysJob): Add pure virtual
member function start taking a list of keys.
* lang/qt/src/qgpgmerefreshsmimekeysjob.h,
lang/qt/src/qgpgmerefreshsmimekeysjob.cpp (class
QGpgMERefreshSMIMEKeysJob): Implement new member function.
--
The new overload makes it easier to refresh some keys if one does
already have Keys.
GnuPG-bug-id: 5951
* lang/qt/src/qgpgmerefreshkeysjob.h,
lang/qt/src/qgpgmerefreshkeysjob.cpp: Change name to
* lang/qt/src/qgpgmerefreshsmimekeysjob.h,
lang/qt/src/qgpgmerefreshsmimekeysjob.cpp: ... this, and adapt the
include guard.
(class QGpgMERefreshKeysJob): Rename to QGpgMERefreshSMIMEKeysJob.
* lang/qt/src/Makefile.am: Adapt mentioned file names accordingly.
* lang/qt/src/protocol_p.h (Protocol::refreshKeysJob): Use renamed
class.
--
To avoid confusion with a similar job for OpenPGP keys with a completely
different implementation, we rename this class to make clear that it is
specific for S/MIME keys.
GnuPG-bug-id: 5951
* lang/cpp/tests/run-getkey.cpp, lang/cpp/tests/run-keylist.cpp (main):
Check used keylist mode.
--
Since Context::setKeyListMode() does not return the error returned by
gpgme, we need to verify explicitly that the keylist mode was set
successfully.
GnuPG-bug-id: 5951
* lang/qt/src/qgpgmedecryptverifyjob.cpp (patch_decryption_result):
Removed.
(decrypt_verify): Remove usage of patch_decryption_result.
--
This reverts most of revision d8e5871dca.
GnuPG-bug-id: 5939
* lang/qt/src/qgpgmedecryptverifyjob.cpp (patch_decryption_result): New.
(decrypt_verify): Call patch_decryption_result.
--
Replace the generic "decryption failed" error with the more specific
"bad passphrase" error if the audit log indicates that a wrong symmetric
password caused the decryption to fail.
GnuPG-bug-id: 5939
* lang/cpp/src/result.h (class Result): Add member function setError.
--
This can be used to replace the error of a result with a more suitable
error.
GnuPG-bug-id: 5939
* lang/cpp/src/editinteractor.cpp
(CallbackHelper::edit_interactor_callback_impl): Check for error _or_
canceled state.
--
Without this canceling an edit operation resulted in a "General error".
GnuPG-bug-id: 5904
* lang/cpp/src/editinteractor.cpp, lang/cpp/src/editinteractor.h
(EditInteractor::parseStatusError): New.
* lang/cpp/src/gpgrevokekeyeditinteractor.cpp
(GpgRevokeKeyEditInteractor::Private::nextState): Handle status
error.
--
With this change the interactor returns a proper error like "Bad
Passphrase" or "Empty Passphrase" instead of an unspecific "General
Error" if a status error occurred.
GnuPG-bug-id: 5904
* lang/qt/src/qgpgmerevokekeyjob.cpp (check_arguments): New.
(QGpgMERevokeKeyJob::start, QGpgMERevokeKeyJob::exec): Call
check_arguments.
* lang/qt/tests/t-revokekey.cpp (RevokeKeyJobTest): Add member functions
testErrorHandling_nullKey, testErrorHandling_invalidReason,
testErrorHandling_invalidDescription.
--
Check that the key is not a null key, that the reason has a valid
value, and that the description lines do not contain endline characters
and are not empty.
GnuPG-bug-id: 5904
* lang/qt/tests/t-revokekey.cpp (RevokeKeyJobTest::testRevokeKeyAsync,
RevokeKeyJobTest::testRevokeKeySync_noReasonDescription,
RevokeKeyJobTest::testRevokeKeySync_oneLineReasonDescription,
RevokeKeyJobTest::testRevokeKeySync_twoLinesReasonDescription): Call
verifyReason.
(class RevokeKeyJobTest): Add private member function verifyReason.
--
gpgme doesn't parse the information, so we run gpg manually to verify
the revocation reason and the description.
GnuPG-bug-id: 5904
* configure.ac: Add -fvisibility=hidden to GPGME_CPP_CFLAGS if gcc
supports the flag.
* lang/cpp/src/Makefile.am (AM_CPPFLAGS): Add GPGME_CPP_CFLAGS.
* m4/ax_gcc_func_attribute.m4: New.
--
With this change all defined symbols are hidden by default, so that they
are not exported anymore. All symbols that are part of the ABI and that
shall still be exported are already marked as having default visibility.
The m4 macro was taken from the website mentioned in the License header
of the file.
