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.
- The duplicate and some typos were introduced in 42aed56a5a
- Also fixes some minor format issues. There's a lot of notes in this docs, we should refactor some.
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
when opening the browser on the result page.
Backtrace looks like this:
Crash: EXCEPTION_ACCESS_VIOLATION_READ at 0x0
File "propagatedownload.cpp", line 234, in OCC::GETFileJob::slotReadyRead
File "moc_propagatedownl_CA5CFSHZDTX34X.cpp", line 86, in OCC::GETFileJob::qt_static_metacall

File "qobject.cpp", line 1256, in QObject::event
File "qapplication.cpp", line 3804, in QApplicationPrivate::notify_helper
GETFileJob::slotReadyRead can be called with a QueuedConnection when the
bendwith manager is involved. In that case, if the QNAM was reset
in between, the reply might have been destroyed.
(This is only speculation based on the backtrace)

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
In particular the `OWNCLOUD_CHUNK_SIZE` as requested per #2449.
I looked through the code and it seems the env vars override the conf file, but I'm not 100 % sure.
The `OWNCLOUD_CRITICAL_FREE_SPACE_BYTES` and `OWNCLOUD_FREE_SPACE_BYTES` are now mentioned in two places.
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.
This was a request of @michaelstingl to document how to configure the proxy manually via the .cfg file for config provisioning purposes.
- Restructured the bullet points into 3 different tables; I believe it's a cleaner approach; maybe this is also applicable to other sections.
- Would be logical to include also settings on proxy auth?
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.
Found with the UB sanitizer:
src/gui/folder.cpp:348:49: runtime error: member access within null pointer of type 'OCC::SyncFileItem'
src/gui/folder.cpp:348:19: runtime error: reference binding to null pointer of type 'const QString'
The backtrace seems to indicate that the account is invalid.
I don't know how this can happen, maybe the account's display
name was changed while the app is running?

The destructor of the PropagateItemJob will access the propagator's
_activeJobList. So the _rootJob needs to be destroyed before it.
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.
(This made TestSyncEngine::testDirDownloadWithError crash sometimes
in the master branch)
