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.
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).
Issue #5224
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.
Use a QSharedPointer to keep the same ownership and
continue passing the SyncFileItems as a const& when
ownership isn't taken. This allows sharing the same
allocations between the jobs and the result vectors.
This saves about 20MB of memory (off 120MB) once all
jobs are created.
* Use a shared pointer to Account everywhere to ensure
the instance stays alive long enough for a sync to terminate
* Folder is now tied to an AccountState
* SyncEngine and OwncloudPropagator tie to an Account and use that
for all jobs they run
Issue: Since the setup wizard currently always replaces the
account, it will always wipe all folder definitions, even when
the actual changes to the account were minor.
