We only want to know if they were touched within the last 15 seconds,
so change the data structure to use a QMultiMap, and sort them by
QElapsedTimer. This allows us to iterate over old entries ordered by
time and to stop once we find a recent entry.
This makes the look-up slower but in most cases the folder watcher
will report any change within milliseconds, and we start from the
most recent. What this really makes slower are actual user file
changes while a fast sync is underways which will need to iterate
over the whole map to find out the file isn't there.
This reduces the growth of the memory usage when downloading a large
amount of files.
We need Qt 5.9 for HTTP2 because, even if Qt 5.8 already has support
for it, there is some critical bug in the HTTP2 implementation which
make it unusable [ https://codereview.qt-project.org/186050 and
https://codereview.qt-project.org/186066 ]
When using HTTP2, we can use many more parallel network request, this
is especially good for small file handling
Lower the priority of the GET and PUT propagation jobs, so the quota
or selective sync ui PROPFIND will not be blocked by them
Since these errors are blacklisted, it can take up to 24h to retry items
that had a 507 error for a while. This way users can intervene and cause
an upload attempt immediately.
It now produces a summary error message indicating the problem.
Adjust blacklist database table to contain 'errorCategory'. This is
useful for two things:
- Reestablishing summary messages based on blacklisted errors. For
example if we don't retry a 507ed file, we still want to show the
message about space on the server
- Selectively wiping the blacklist: When we have ui for something like
"I deleted some files, please retry all files now!", we want to
delete all blacklist entries of a specific category only.
* A bunch of code was determining sync status by ad-hoc comparing some
progress info fields. It can now just check the status, making it
easier to comprehend.
* There's a clear indication for "a new sync is starting", which helps
wiping the issues tab at the right time.
For now we use them for:
* csync errors: This allows them to appear in the sync issues tab
* insufficient local disk space, as a summary of individual file errors
Insufficient remote space will use them too, as might other issues that
are bigger than a single sync item.
Before, blacklisted errors were set to FileIgnored status and hence
displayed as warnings. Now, they have their own BlacklistedError
category which allows them to appear as errors in the issues list and in
the shell integration icons.
* For conflicts where mtime and size are identical:
a) If there's no remote checksum, skip (unchanged)
b) If there's a remote checksum that's a useful hash, create a
PropagateDownload job and compute the local hash. If the hashes
are identical, don't download the file and just update metadata.
* Avoid exposing the existence of checksumTypeId beyond the database
layer. This makes handling checksums easier in general because they
can usually be treated as a single blob.
This change was prompted by the difficulty of producing file_stat_t
entries uniformly from PROPFINDs and the database.
Issue #5783
When the directry that should be removed by selective sync contains changes,
we ignore the whole sub tree instead of only ignoreing new files.
We cannot ignore the whole directory, we need to ignore only the directory
that do not have files to remove
Use qCInfo for anything that has general value for support and
development. Use qCWarning for any recoverable error and qCCritical
for anything that could result in data loss or would identify a serious
issue with the code.
Issue #5647
This gives more insight about the logs and allow setting fine-tuned
logging rules. The categories are set to only output Info by default
so this allows us to provide more concise logging while keeping the
ability to extract more information for a specific category when
developping or debugging customer issues.
Issue #5647
Before this patch, to deep folder would just be ignored, without any feedback.
This patch makes it so deep folder are properly shown as ignored in the UI.
Also increase the MAX_DEPTH
Issue: #1067
* 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
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
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.
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.
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.

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.
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 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
Two bugs:
- The change filed are not considered as move, they are re-downloaded
but the old file was not removed from the database. The change in
owncloudpropagator.cpp takes care of removing the old entries.
- Next sync would then remove the file in the server in the old folder
This was not a problem until we start reusing the sync engine, and
that the _renamedFolders map is not cleared. We were before deleting
a non-existing file. But now we delete the actual file.
Also improve the tests to be able to do move on the server.
This include support for file id.
Issue #5192
Before it was in Folder, however, the command line client does not
have the Folder class. To not duplicate code, the function to generate
the sync journal name went to SyncEngine class.
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).
