I got into a situation where the model would endlessly request the directory
contents from the server because we did not notice yet that the server
is actually in maintenance mode while we were expanding the tree view when
changing the tab to the account or when just expanding it by clicking.
This would happen if the directory would first need to be created
through an mkdir propagation job. This job's itemCompleted signal
would trigger the directory to show as SYNC even though its children
are still propagating.
Fix the issue by tracking the sync count for each file, affecting
its parents. This allows us to get rid of the O(n) vector lookup
for each status query, and properly track the hierachical sync
status of a directory.
This also removes the itemCompleted signal emission from the
PropagateDirectory job. Since we only needed for overlay icons, and
since this job doesn't do any direct propagation, we can remove it
to ensure that we won't call itemCompleted twice for the item attached
to Propagate*Mkdir jobs (since the PropagateDirectory is backed by
the same SyncFileItem, instruction and status).
The current way of tracking the need to update the metadata without
propagation using a separate flag makes it difficult to track
priorities between the local and remote tree. The logic is also
difficult to logically cover since the possibilities matrix isn't
100% covered, leaving the flag only used in a few situations
(mostly involving folders, but not only).
The reason we need to change this is to be able to track the sync
state of files for overlay icons. The instruction alone can't be
used since CSYNC_INSTRUCTION_SYNC is used for folders even though
they won't be propagated. Removing this logic is however not possible
without using something else than CSYNC_INSTRUCTION_NONE since too
many codepath interpret (rightfully) this as meaning "nothing to do".
This patch adds a new CSYNC_INSTRUCTION_UPDATE_METADATA instruction
to let the update and reconcile steps tell the SyncEngine to update
the metadata of a file without any propagation. Other flags are left
to be interpretted by the implementation as implicitly needing
metadata update or not, as this was already the case for most file
propagation jobs. For example, CSYNC_INSTRUCTION_NEW for directories
now also implicitly update the metadata.
Since it's not impossible for folders to emit CSYNC_INSTRUCTION_SYNC
or CSYNC_INSTRUCTION_CONFLICT, the corresponding code paths in the
sync engine have been removed.
Since the reconcile step can now know if the local tree needs metadata
update while the remote side might want propagation, the
localMetadataUpdate logic in SyncEngine::treewalkFile now simply use
a CSYNC_INSTRUCTION_UPDATE_METADATA for the local side, which is now
implemented as a different database query.
Add a missing call that we currently only do in slotItemCompleted.
This would normally only affect the first sync and would have
gotten properly update at the end of the sync anyway.
To be able to test the SyncEngine efficiently, a set of server
mocking classes have been implemented on top of QNetworkAccessManager.
The local disk side hasn't been mocked since this would require adding
a large abstraction layer in csync. The SyncEngine is instead pointed
to a different temporary dir in each test and we test by interacting
with files in this directory instead.
The FakeFolder object wraps the SyncEngine with those abstractions
and allow controlling the local files, and the fake remote state
through the FileModifier interface, using a FileInfo tree structure
for the remote-side implementation as well as feeding and comparing
the states on both side in tests.
Tests run fast and require no setup to be run, but each server feature
that we want to test on the client side needs to be implemented in
this fake objects library. For example, the OC-FileId header isn't
set as of this commit, and we can't test the file move logic properly
without implementing it first.
The TestSyncFileStatusTracker tests already contain a few QEXPECT_FAIL
for what I esteem being issues that need to be fixed in order to catch
up on our test coverage without making this patch too huge.
This is a move away from the original policy where jobs
would only follow redirects in special cases.
Two restrictions are in place:
1. We do not allow protocol downgrades (https -> http)
2. We stop redirects after we find them looping (e.g. old = new url, or
indirectly when looping 10 times).
This is closer to RFC conforming behavior, although currently
we will treat 301 replies like they were 302. This is for a separate
commit.
Error handling (and display) also needs improvement.
Addresses #2791
Once upon a time, the SyncEngine was instantiated once per sync. But now that
the SyncEngine is kept between sync, we need to reset all these variable between
syncs.

Could be the cause of #5092 and the cost is higher than the benefit if this is the case.
A network request taking more than 30 seconds isn't something unlikely in this world
and shouldn't be a good reason to abort. We should try to untangle the threads
dependencies to properly fix this if possible instead.
It opens a window and connects to a cipher test
page, showing the output from there, that helps for debugging.
The window is enabled by setting the environment variable

Missing deleteLater when the CleanupPollsJob aborts.
This is only a problem if the SyncEngine is kept alive a long time. Which is
usually not the case in the configuration where poll jobs are used.
While loading the account, only override the server url if Theme::forceConfigAuthType
is set. This restore the behavior from the client 2.1 for theme that did not
use Theme::forceConfigAuthType.
Issue: owncloud/enterprise#1418
This was removed in 0194ebb222
because it breaks on Linux. However, it looks like it is correct
for Windows. In the meantime the surrounding ifdef has changed
from !Q_OS_MAC to Q_OS_WIN, so reverting it makes sense.
Since the SyncEngine now quits and waits for the discovery thread,
the main thread can enter a deadlock where the discovery thread waits
for its directory result.
Add a 2 seconds timer to the discovery thread wait condition
to limit the deadlock time.
This disables the workaround 487e1fdca5ee04fc98c1ed77898df70d740967c8
for servers that are new enough to support fine grained permissions
on federated shares.
The consequence is that the 'reshare' permission is now granted by
default and that users can edit permissions on the usual fine-grained
level again.
The way the client deals with servers <9.1 is unchanged.
Use a QMap to avoid using a full hashtable for only a few entries, and
clear the QMap once we're done with the measuring. This saves a few
hundred bytes per job during propagation that would otherwise only be
freed at the end of the sync.
During propagation, we create a line for each file, taking memory, but
we delete all lines passed 2000 right at the beginning of the next sync.
Since the user has little chances of being able to read past those 2000
lines in the log, we might as well keep it capped at 2000 also during
propagation to prevent it from eating memory.
The SyncRunFileLog owned by the Folder must be destroyed after the
SyncEngine since the SyncEngine will abort during destruction, resulting
in all jobs being aborted.
It's possible that this crash only happens with a debug build.
The FolderWatcher inserts files to be marked as SYNC and we
currently assume that all file statuses will be updated by the
following sync. It's however possible that the FolderWatcher
notify us of a change that csync won't consider necessary to
propagate, in which case a new status wouldn't be pushed and
the file manager would continue showing this file as syncing.
Re-push the file status when emptying the dirty files list
before propagating to avoid this issue, most likely the OK
status.
No need to allocate (and initialize to 0) a 10 MiB buffer for each files, even
when most files are much smaller than that.
So make sure the buffer that we allocate is not bigger than the file size.
And Also 10 MiB is a bit big for a buffer. 500 KiB should be more than enough.
(Too big allocations can cause problem because of memory fragmentation and such)
We first need to set the abort flag to csync and then aborting the discovery
job, otherwise, the discovery thread could start a new job in the mean time.
We also need to make sure that the thread has existed before we destroy the
exclude list.
Events from the crash reporter suggest that the QNAM and its
child replies might get deleted before returning from this method
and the only possible cause we can see is that the inner event
loop has something to do with it.
Try keeping a ref on the QNAM while in this method to make sure
that it won't get deleted by the inner event loop.
Same fix as in commit 60c101d9

FolderDefinition::save and load escapes the alias. We also need to escape
it when we remove it.
New folder can't be created with alias that needs escaping, but old folder
from old config may still exist, and we must allow user to delete them.
For issue #4927:
On Windows 10, we get a notification after the sync is finished for file that were
just downloaded. The guard we have against our "own changes" are only working when
the sync is running and the OwncloudPropagator still alive.
Setting the Environment variable only for owncloud makes in inconsistant with
other Qt application running at the same time.
The users can still set it themself for the whole desktop if they wish.

Previously rejecting any kind of certificate meant that the user
was never asked again, even if the certificate changed.
Now we keep track of which certificates were rejected and ask again
if the ones mentioned in the ssl errors change.
mitmproxy is excellent for testing this.
* Progress: Don't count dirs without propagation jobs #4856
These directory SyncFileItems are necessary for bookkeeping
but should not influence the progress display at all.
* Progress: Skip ignored files #4856
The problem in this case is if we rename the file "xxx" to "invalid\file".
The rename will fail because the new filename constains a slash, and it
will be blacklisted.
But then if the user re-rename the file to "valid_name", then we should
invalidate the blacklist entry and retry to upload. But we did not do
that because renaming don't change the mtime and we did not store the
rename target in the database

This fixes an issue in which too many jobs are started un parallel
while uploading many files, which could cause too much memory usage as the
chunks are stored in memory.
Probably the fix for #4611
Issue #4855
A typo in the context string made the translation lookup fail.
But also the %Ln was not recognized as a plural form by transifex, so only
the singular was translated
The assert was there to make sure that this case wasn't happening
to eventually be properly tested. Remove the assert for now but this
codepath should eventually be unit tested using this specific situation.
Since the windows implementation first does cache lookups using the
path string, directories need to be passed identically as through
RETRIEVE_FILE_STATUS.
Change the convention to never have a trailing slash for directories
in the protocol. This allows the convention to be applied without
having to access the disk (since we'd need to know if the path is
represented by a directory) and also matches the convention of the
rest of the sync engine. Individual file manager plugins are then
responsible of handling pushed paths as not ending with a trailing
slash.
This also:
- Moves the trailing slash removal logic from the SyncFileStatusTracker
to the SocketApi class
- Remove the unneeded QString::normalized call in fileStatus, since
this should already be done by the FolderWatcher and plugins
Since the statuses are cached and that we can't invalidate the cache,
sending NOP would need to be overwritten by the default OK status
once the client successfully connected. But instead of remembering
which files we NOPed, rather wait until we are ready to sync before
sending the REGISTER_PATH message to the socket API client. It will
also prevent the client from sending unnecessary RETRIEVE_FILE_STATUS
requests.
Also remove AccountState::canSync, since it does the same as
isConnected and syncing is not an account responsibility.
Go through fileStatus like other cases to make sure that all use
cases go through the same code path. This also makes sure to use
lookupProblem which will use lower_bound which is more efficient
for larger sets of sync problems.
This also fixes the issue with lookupProblem that prevented it to
properly match an empty pathToMatch, caused by the fact that the
problem map contains relative paths not starting with a slash.
Make sure that we push the new status when the status of the SyncEngine
changed. SyncEngine::started comes a bit late, only when the propagation
starts, although it's better in this case since child folders will
only switch to Sync in aboutToPropagate.
Also fix an issue with SyncEngine::findSyncItem when using an empty
fileName; this would match and return the wrong item, even though
not currently happening with the code since fileStatus won't call
it with an empty fileName anymore.
As before, we rely on metadata-update SyncFileItem entries for parent
directories to notify us that a directory contains files to propagate,
and to know when all children were propagated through its itemCompleted
signal.
Those metadata SyncFileItems however have a None direction and we need
to add a explicit directory check to show them as Sync.
This fix also handles new files as well as existing ones, so no need
to keep a separate logic for new files.

Issue #4773
When a conflict-rename or a temporary-rename fails, notify the
LockWatcher. It'll regularly check whether the file has become
accesible again. When it has, another sync is triggered.
owncloud/enterprise#1288
If the downloaded file is empty but the PROPFIND previously announced it
should not have been empty, this might mean the file was somehow corrupted
because of a bug on the server and that we should therefore not accept
the file.
Normaly we accept a change between the actual size of the file and what we
got during discovery because the file might have been updated to a new version
inbetween. But after this patch we won't accept the file if it was replaced
by an empty file.
Will help for issue #4583
