This gets rid of the csync_statedb sqlite layer and use
the same code and same connection as the rest of the SyncEngine.
Missing functions are added to SyncJournalDb and change a few minor
things (like changing SyncJournalFileRecord::_modtime to be an int64
instead of a QDateTime, like it was in csync).
The current implementation would return the same value whether the query failed
or if no row would be found. This is something that is currently checked by csync
and needs to be provided if we want to use SyncJournalDB there.
Adjusted all call sites to also check the return value even though they
could still just rely on rec.isValid(), but makes it more explicit as to what
happens for database errors in those cases, if we ever want to gracefully handle
them.
This is motivated by the fact that QMetaObject::noralizeSignature takes 7.35%
CPU of the LargeSyncBench. (Mostly from ABstractNetworkJob::setupConnections and
PropagateUploadFileV1::startNextChunk). It could be fixed by using normalized
signature in the connection statement, but i tought it was a good oportunity
to modernize the code.
This commit only contains calls that were automatically converted with clazy.
Now that csync builds as C++, this will avoid having to implement
functionalities needed by csync mandatorily in csync itself.
This library is built as part of libocsync and symbols exported
through it.
This requires a relicense of Utility as LGPL. All classes moved into
this library from src/libsync will need to be relicensed as well.
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
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.
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.
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
* 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
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.
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.
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).
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.
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.
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 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.
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)
