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.
This will allow us to unify data structures between csync and libsync.
Utility functions like csync_time and c_std are still compiled as C
since we won't need to be coupled with Qt in the short term.
Previously, we only checked the hiddenness of the target file and
ignored the hiddenness of the containing folders. This lead to
undesired behavior when people synced their home folders and there
was a folder watcher notification for a non-hidden file in one of
the hidden folders.
I'm not fully sure why, but sometimes notifications for .foo/bar were
already ignored, but notifications for .foo/bar/car were not. This may
be because of how we set up the FolderWatchers on Linux.
The new behavior is to check all path components for hiddenness, up
until the base path (but excluding the base path, so using a hidden
folder as a sync folder will work).
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 will help moving the SyncEngine construction in the constructor
and allow moving functionalities from Folder to SyncEngine or its
delegated objects.
The creation doesn't need to be separated from the SyncEngine anymore.
This allows the SyncEngine to be created in fewer steps if we want to
use it in tests.
This moves most of the direct csync code from Folder into the SyncEngine.
The exclude file logic for the context has been wrapped using the
existing ExcludedFiles class as well.
Introduce a global ExcludedFiles instance to avoid loading the global
exclude lists several times.
One could still add per-folder exclude lists by checking these after
the global ones.
