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
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:348:19: 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)
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.
So the title of the column is fully visible.
Adjust the default size and the size policy of the label so it behave
correctly as the window get resized
Issue #5600
The crash reporter shows many crashes in OwncloudPropagator::scheduleNextJob.
We don't really know what could be the cause, but it's probably because
the _activeJobList contains dangling pointer.
So this patch makes sure to remove all the jobs from this list as they get
destroyed.

My theory is that the AccountState stored in a property of the job was destroyed.
before the job timed out.
Therefore, the qobject_cast within the qvariant_cast would call the metaObject()
virtual function on a dangling pointer.
Fix it by storing a QPointer instead which will track the deletion.
The test sets OWNCLOUD_MAX_PARALLEL to 1 to disable parallelism.
But since the max amount of parallelism is twice as much, that does not
work.
So change the way we compute the hardMaximumActiveJob: Use the value of
OWNCLOUD_MAX_PARALLEL to maximize this amount and base the maximum amount
of transfer jobs on it instead of the other way.
A result of this change is that, in case of bandwidth limit, we keep the
default of 6 non-transfer jobs in parallel. I believe that's fine since
the short jobs do not really use bandwidth, so we can still keep the same
amount of small jobs.
We can do that because the only changes that were in master but not in 2.3 were the
translations change and documentation change, and the support for the 'M' permission
which we want in 2.3.
The sync engine rely on the 'M' in premission to ask for confirmation
(As requested in issue #5340)
But we only want to ask the premission for the 'root' of the mounting point and not
for every subfolders within it.
So we change the discovery phase in a way that it does not keep the 'M' for
children within the external storage.
Added two checkboxes in the Account Wizard in the advanced page to change the first options.
Also added a checkbox in the general settings to ask for confirmation for external storages.
Theme options allow to hide the checkboxes in the wizard.
As described in issue #5340
Stale chunks might be there because a file was removed or would just not
be uploaded, for any reason.
We just start the DeleteJob but we don't care if it success or not.
Relates to https://github.com/owncloud/core/issues/26981
One of the test is testing the case where the file is modified on the server
during the upload. So this test the precondition failed error.
The FakeGetReply logic was modified because resizing a 150MB big QByteArray
by increment of 16k just did not scale when downloading a big file.
Relates to https://github.com/owncloud/core/issues/26981
We do not track the success or error of the DeleteJob because it does not
matter. If it fails, it might be because the chunks were already removed.
If not, the chunks will be stale, but the server must anyway do a few
cleanup from time to time because we do not always remove the chunks
Otherwise it might happen that the model is inconsistant and this can
lead to crash in the worst case.
(For example, if there was a "fetching" label, and we hide it because it
was a 404. In this case, we would not call begin/endRemoveRows, so the
view could still call the model with an index of row 0, that used to be
for the label, but now correspond to the first element of _subs. And
because _subs is empty, this could lead to crashes)
This could make sure that the network job gets deleted if the parent job gets
deleted, and would avoid crashes like:

(#5329)
The rules to select the webdav url are now:
- If the server reports that the new chunking algorithm is working,
always use remote.php/dav/files/<username>
This capability can be overriden with an environment variable
- Otherwise, use the dav path provided by the theme, which defaults to
remote.php/webdav
This means that with the newer server, the branding can no longer override
the webdav URL. If there is still an usecase for the branding to do so, we
need to find another way to override it. But it is now more complicated to
configure as might need include the username and need different endpoint
depending on the operations (chunks or not)
Issue #4007
As the URL might be print on the logs.
Also don't change the scheme from http to owncloud.
This was required before when we were using neon through csync, but now that
we use QNAM for everything we don't need it. The credentials from the account
are used.
We are going to change the webdav path depending on the capabilities.
But the SyncEngine and csync might have been created before the capabilities
are retrieved.
The main raison why we gave the path to the sync engine was to pass it to csync.
But the thing is that csync don't need anymore this url as everything is done by the
discovery classes in libsync that use the network jobs that use the account for the urls.
So csync do not need the remote URI.
shortenFilename in folderstatusmodel.cpp was useless because the string is the
_file of a SyncFileItem which is the relative file name, that name never
starts with owncloud://.
All the csync test creates the folder because csync use to check if the folder
exists. But we don't need to do that anymore
The "S" in the permission is only for the "Shared with me" files.
It is only used to show the shared status in the overlay icons.
But we also wish to show the shared status for files that are shared
"by" the users. We can find that out using the 'share-types' webdav
property. If set, then we are sharing the object.
We fake a 'S' in the permission as for our purpose, they mean the same.
Issue #4788
As the file can be some hunreds of megabytes, allocating such big arrays may
cause problems.
Also make the timeout a bit bigger so the test can rununder valgrind.

The ownCloud 9.1 server has a data-fingerprint property that the admin must
change in case of backup restoration. When this change, the client understands
that a backup was restored, and will generate conflict files and re-upload
new files.
The heuristics based system checks that there is at least two files wose mtime
is put back in the past and no files that goes forward. In that case we ask the
user before creating the conflicts.
This commit disable the heuristics for newer server that have the data-fingerpint.
And change the heuristics to two hours because we want to avoid false positive due
to some clock error, and that 2 hours of lost due to backup restoration is probably
not so bad.
We only ask the user in the heuristics based aproach so in practice this mean that
the "backup-detected" dialog will no longer appear with newer server.

Two problems:
- In the discovery phase, we need to check the selective sync entries of
the source path in case of renames.
- When the rename is done, we need to actually update the black list in the
database.
Some tests (such as FolderManTest) can polute the config file with invalid
accounts.
(That's because most of the code, (even in libsync) always instentiate a ConfigFile)
The crash reporter shows a lot of crashes in sqlite3_clear_bindings
which seems to indicate that _stmt is null. We should guard against
a null value in order to avoid crashing.
This should only happen if the prepare call fails. We don't usually
check the return value of the prepare call, but if _stmt is null, the
exec call should return false, not true. We check the result of the
exec call, so this should then abort the sync with an error, rather
than crashing.
We ignored csync log, but we also need to silent Qt debug output.
We need to ignore it at the very begining because there might be
qDebug also in account creation.

This is not sufficient as it is not working for the Socket API.
Next commit will fix it in another layer.
Also, not ignoring paths that are not inside the folder is wrong
as it might still happen if the name has a different casing
This reverts commit d5a481f132.
(cherry picked from commit 904cd46f75)
This is important because we compare the paths from the file system watcher if it
starts with this path.
Same in the SocketAPI where we need to use cannonical paths in the REGISTER_PATH command,
as the plugin themself will do this comparison.
