I'm confident this is unnecessary. The original bug in #3283 was
to call ignoreSslErrors() without an argument in the 'accept'
case, which meant ignoring *all* subsequent SSL errors.
With that fixed, explicitly aborting the reply and resetting QNAM
is not needed since not ignoring the error will lead to the SSL
handshake failing.

* Allow creating nameless shares
* Display token as name for nameless shares
(both to be consistent with server)
* Allow changing a share's name by editing it in the table
* Minor adjustments
Starting from oC 10.0.0 having several public link shares with
different attributes for a path will be supported. This adds
functionality to create, edit and delete these public link shares.
The behavior is currently gated by server version, but should be
adapted to use a capability as soon as one is introduced, see
owncloud/core#27622.
The UI reduces to a single-share version when talking to older servers.
Testing scenarios:
* Link sharing is disabled (by capability, not by theme)
* Required passwords
* Required expiry
* Forbidden 'allow upload' for folders
* New and old servers
Newer servers will have the option of hiding version, versionstring, edition
and productname. They will always send the full information in the capabilities.
By default QNetworkReply::errorString() often produces messages like
"Error downloading <url> - server replied: <reason>"
but the "downloading" part invariably confuses people since the
error might very well have been produced by a PUT request.
This commit produces clearer error messages for HTTP errors.
Additionally:
* Remove some unnecessary null checks from slots connected to
network job signals and document that these signals never send
null replies.
* There was a bug where AbstractNetworkJob::_timedout wasn't
set when derived classes overrode slotTimeout. We now ensure
it's always set by disallowing overrides of slotTimeout.
Instead it now calls onTimedOut, which allows custom handling.
* Several subclasses declared errorString, isTimedOut. Move
these to AbstractNetworkJob.
* Unify handling of OC-ErrorString (via the new, general
Job::errorString)
* Add documentation in various places.
Before we would only open the part of the url that the users entered.
Now if the wizardUrlPostfix is used this is should be appended to that

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
* make target duration a client option instead of a capability
* simplify algorithm for determining chunk size significantly
* preserve chunk size for the whole propagation, not just per upload
* move options to SyncOptions to avoid depending on ConfigFile
in the propagator
* move chunk-size adjustment to after a chunk finishes, not when
a new chunk starts
Previously the check box was checked if *any* of its sub-permissions
were granted. This can hide the fact that only a limited subset of them
are actually granted.
The new behavior is to display as "partially checked" if only some
of the sub-permissions are available. Clicking the check box itself
still toggles between granting all or none of them.
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.

The backtrace seems to indicate that the account is invalid.
I don't know how this can happen, maybe the account's display

The destructor of the PropagateItemJob will access the propagator's

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.

I didn't want to touch this visible translated string in a

For Qt versions before 5, we continue to show the build-time version

In 8ef11a38c9, we started blacklisting

So make sure we expire if 0 seconds have expired
The backtrace looks like:

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.
This is a possible fix for #3850, applying custom window flags (http://doc.qt.io/qt-5.8/qt.html#WindowType-enum) on the connection method dialog. These avoid resizing the dialog and displaying a maximize button on OS X and context help button on Windows.
It is possible to create files with filenames that differ
only by case in NTFS, but most operations such as stat and
open only target one of these by default.
When that happens, we want to avoid uploading incorrect data
and give up on the file.
Typically this situation should never occurr during normal use
of Windows. It can happen, however, when a NTFS partition is
mounted in another OS.
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.
* For requests:
- reuse the original QNetworkRequest, so headers and attributes
are the same as in the original request
- determine the original http method from the reply and the request
attributes
- keep the original request body around such that it can be sent
again in case the request is redirected
* Simplify the interface that is used for creating new requests in
AbstractNetworkJob.

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.
This leads to crashes since we changed the connection to the parent
jobs not to be queued anymore.
We don't really need to bubble up the finished state through
parents in that case, and it would also mean that we'd recurse
all the way through leaves as we go up to each parent. So just call
abort directly on the OwncloudPropagator and make sure the abortion
call is posted to the event loop.
Avoid using connections to report up the job tree for signals
that we can directly communicate to the OwncloudPropagator.
This slightly reduces the memory usage and avoid passing those calls
through the whole parent chain.
In preparation for the PropagateDirectory refactoring, simplify things
by removing WaitForFinishedInParentDirectory, which is currently
implemented as a one-level check.
This value is important for directory items, but is however never
used since a directory CSYNC_INSTRUCTION_RENAME item will always be in
PropagateDirectory::_firstJob, which will have to pass through its own
PropagateDirectory job's parallelism() before reaching the parent's
_subJobs optimization.
Since PropagateDirectory::parallelism can only return WaitForFinished
or FullParallelism, that value is lost. So this commit doesn't
change the behavior for directories, and allow file renames to be
scheduled in parallel across directories (which isn't a problem).
It could be possible that _firstJob is marked as finished if
aborted before its parent PropagateDirectory was marked as finished,
allowing a posted scheduleNextJob call to schedule the child job
in-between.
- I checked every occurence of a '%2' and make correct use of the
QString::arg overload that takes several argument instead of chaining
them, because the first argument can contains a '%1'
- I tried to look for every label that they either use plain text or richtext
and escape the user provided strings in there.
By default, followRedirects is true for all requests, to transparently
handle redirections. In the wizard, we have special redirect-handling
code though and that was being skipped.
Setting the flag to false allows the wizard to be aware of redirects
and to handle them in the correct way. Tested with the server described
in
https://github.com/owncloud/administration/tree/master/redirectServer
There's a second bug here, where followRedirects always converts
redirected requests to the GET verb. That means redirected PROPFINDs
will never have worked. This change un-breaks them for the wizard only.
There should be no case that previously worked that stops working now.
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.
This reverts commit e1f5a49c21.
Retrying uploads with insufficent storage errors frequently leads to
high server traffic. See #5537 for links and a sketch of a correct
solution.
If we call
setConfiguration(QNetworkConfiguration());
This sets an invalid configuration on the QNAM.
But later, when we really go online because interfaces are discovered,
QNetworkAccessManagerPrivate::_q_onlineStateChanged is called (with isOnline=true).
And this will set the state to disconnected because customNetworkConfiguration is
true, and the networkConfiguration state is disabled.
The workaround we to fix another bug on Windows in which the default network
configuration was not behaving properly.
The issue on linux is hard to reproduce and only happen in some condition,
but it was reproduced on smashbox when they run two owncloudcmd at the same time.
Issues: #4720 , #3600
We were removing the wholme journal db when the user wanted to keep all files,
But that would also remove the selective sync lists.
We should only remove the metadata table.
Issue #5484
- Put all tests in the bin directory so that DLLs can be loaded
- Add missing exports
- Skip tests that use code depending on zlib
- The "GMT" timezone is named differently, use the int constructor instead
5 tests are still failing, it's not really worth fixing at the moment
since no developper is currently using Windows as its main platform.
It could be possible that _firstJob is marked as finished if
aborted before its parent PropagateDirectory was marked as finished,
allowing a posted scheduleNextJob call to schedule the child job
in-between.
Previously, we'd try migrating from legacy settings if reading
the settings failed with an error. Now, we try again after a
couple of seconds and eventually give up.
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
We now delete subjobs as their propagation is complete. This allows us
to also release the item by making sure that nothing else is holding a
reference to it.
Remove the stored SyncFileItemVector from SyncEngine and SyncResult
and instead gather the needed info progressively as each itemCompleted
signal is emitted.
This frees some holes on the heap as propagation goes, allowing many
memory allocations without the need of requesting more virtual memory
from the OS, preventing the memory usage from increasingly growing.
This was to catch duplicate emissions for PropagateDirectory but we
don't emit this signal anymore from there.
This fixes a warning about PropagatorJob not being a registered metatype.
This reverts commit fe42c1a818.
Previously if you paused/unpaused a folder for a disconnected account
they would prepare to sync and thus display the 'Waiting...' text. With
this change, folders that can't possibly sync don't show text like
this.
When account connectivity changes, all unpaused folders will be
scheduled anyway.
The avatar image is fetched from the server async, thus connect a signal
from the account if the avatar changes.
Server feature https://github.com/owncloud/core/pull/26872 is needed.
The avatar pixmap is fetched from the server by the Connectionvalidator,
once it has validated the user name, it queries the avatar pixmap.
If the server does not have the avatar route, an empty pixmap is stored.
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
The current logic tried to avoid a DB lookup just to fetch whether
the file is shared or not since that info is already in the
SyncFileItem. The implementation would however need to decrease the
sync count for itself (and parents) before emitting the new status,
thus emitting the OK status for parents before that last child that
ended the propagation for that folder.
Change the implementation to achieve what we want: give the
possibility to decSyncCount to use a pre-fetched sharing state while
still doing the emission for all involved files. This ensures that
the leaf file also gets its status emitted before its parents.
Issue #4797
We currently push the SYNC status for all files that will be propagated,
and then the OK status when those files are propagated.
On top of this, we send those statuses to all clients connected, even
if the socket is kept open by an application that only needed to show
a file open dialog. On macOS we're also using an NSConnection which
means that we have to wait for the RPC call to return from the
extension, which makes bulk status changes possibly heavy.
Reduce the time spent needlessly sending status pushes by limiting
them to files requested through that socket since it connected.
To limit the data to store, only remember the parent directory of
files requested, and store those in a bloom filter.
Note that this adds a requirement to shell extensions: they should
make sure that the status cache only contains entries that have been
requested through the socket API. In other words, the status cache
must be empty when each socket client connects to the socket API.
Otherwise the cached icon type will be shown to the user, and the
SocketAPI won't push new status for that file if it didn't receive
a RETRIEVE_FILE_STATUS.
- Use the looked-up method index also for the invocation
- Do the method name concatenation already on QByteArray since we'll
convert anyway
- Use staticMetaObject instead of metaObject()
Shrinks owncloud binary by 24 KB and libowncloudsync by 14 KB.
I don't know if it has influence on memory usage or runtime speed though.
Was worth a try.
Previously this wasn't happening for errors that were not
NormalErrors because they don't end up in the blacklist.
This revises the resetting logic to be independent of the
error blacklist and make use of UploadInfo::errorCount
instead.
412 errors should reset chunked uploads because they might be
indicative of a checksum error.
Additionally, server bugs might require that additional
errors cause an upload reset. To allow that, a new capability
is added that can be used to advise the client about this.
This displayName() seemed to be based on Account::user() which used
to call _credentials->user(). But then we repurposed user() to be
davUser() and this usage wasn't updated to point back to the username
used for the credentials.
Some custom server use persistent cookies with the auth token. So we should
clear all the cookies when disconnecting.
Account::clearCookieJar is only called from the HTTPCredentials. This funciton
is not used for shibboleth.
There is probably no reasons to keep the HTTP cookie anyway.
Issue #5370
The re-enables the UI, uses Qt API for importing and
stores the certificate/key in the system keychain.
People who had set up client certs need to re-setup the account. This is ok
since it was an undocumented feature anyway.
Fixes#5408#5407.
The problem was that cleanup of the credentials page set the
credentials of the account back to dummy, thereby overriding
things like shib usernames.
This should be broken since a932eac832.
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 csync log level was only set up on startup, and for log files.
Fix the issue by making Logger::isNoop rely on being explicitly activated
for the log window instead of relying on the presence of a connected
signal, and move the csync log level logic in Logger.
The compiler seems to use signed enums and we need to reserve an extra
bit for the sign to avoid the 2 value to overflow and being interpreted
as -2 when read, and thus not being correctly compared to the full enum
value.
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
Some listeners detect whether a sync is finished by checking
for isUpdatingEstimates and completedFiles >= totalFiles. But
if a sync didn't transfer any files we never sent signal
with these values. Now we do.
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
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.
Relates issues #5260, #5109
Otherwise progress listeners think it's still the last-completed
item when the next sync starts. This lead to spurious entries in
the "Recent Changes" list.
