Backtrace looks like this:
Crash: EXCEPTION_ACCESS_VIOLATION_READ at 0x0
File "propagatedownload.cpp", line 234, in OCC::GETFileJob::slotReadyRead
File "moc_propagatedownl_CA5CFSHZDTX34X.cpp", line 86, in OCC::GETFileJob::qt_static_metacall

File "qobject.cpp", line 1256, in QObject::event
File "qapplication.cpp", line 3804, in QApplicationPrivate::notify_helper
GETFileJob::slotReadyRead can be called with a QueuedConnection when the
bendwith manager is involved. In that case, if the QNAM was reset
in between, the reply might have been destroyed.
(This is only speculation based on the backtrace)

I believe the problem is caused because 'this' was deleted in ConnectionValidator::reportResult
as the signal connectionResult gets emited. The AccountState::slotConnectionValidatorResult
slot does indeed call slotInvalidCredentials which might call {Shibboleth,Http}Credentials::fetchFromKeychain
which might emit fetched directly, which will call AccountState::slotCredentialsFetched
which deletes the _connectionValidator
So use deleteLater when deleting the _connectionValidator, hoping this helps
This was a request of @michaelstingl to document how to configure the proxy manually via the .cfg file for config provisioning purposes.
- Restructured the bullet points into 3 different tables; I believe it's a cleaner approach; maybe this is also applicable to other sections.
- Would be logical to include also settings on proxy auth?
When there is no errors _syncResult.firstItemError() is NULL, and accessing
it's _file member is an undefined behavior. (Thankfully, createGuiLog did not
use the string when the count was 0, but we are not supposed to create
null references.
Found with the UB sanitizer:
src/gui/folder.cpp:348:49: runtime error: member access within null pointer of type 'OCC::SyncFileItem'
src/gui/folder.cpp:348:19: runtime error: reference binding to null pointer of type 'const QString'
The backtrace seems to indicate that the account is invalid.
I don't know how this can happen, maybe the account's display
name was changed while the app is running?

The destructor of the PropagateItemJob will access the propagator's
_activeJobList. So the _rootJob needs to be destroyed before it.
Order of destruction is the reverse of the order of the members in
the class. So put it at the end so it can be destroyed first.
(This made TestSyncEngine::testDirDownloadWithError crash sometimes
in the master branch)
I didn't want to touch this visible translated string in a
patch release so I just switched the data.
For Qt versions before 5, we continue to show the build-time version
of OpenSSL but it's clearly marked as such.
In 8ef11a38c9, we started blacklisting
SoftError for 0 seconds. But if the two sync happen with less than
1s interval, we would still prevent them to happen.
So make sure we expire if 0 seconds have expired
The backtrace looks like:
File "atomic_base.h", line 396, in QString::~QString
File "qlist.h", line 442, in OCC::FolderStatusModel::slotUpdateDirectories
This is the only QList operation, and it may crash if the list is empty.
It can be empty if the propfind returned empty results.
I'm not sure how this can be possible to have an empty list there since
the server is always supposed to return at least one entry, for the directory
itself. But it can happen if a directory was transformed in a file, or
if there is a bug on the server.
