Merge : Synchronising groups. #1165

louib · 2017-11-03T20:28:06Z

This changes the merge function to match the groups using the UUIDs, the same way we match the entries. This allows us to do basic conflict resolution on the groups, so we can update the basic information such as the name and the location.

I also removed the shallow parameter to Group::clone in favor of CloneFlags, just like for Entry::clone.

I think the next step for the merge function would be to separate the change detection (new entries, new groups, entries or groups changed) and the actual modification of the destination database. This would allow us to fix a couple of issues with the merge function. For example, we could easily implement a dry-run functionality, and we could detect when the database was really modified by a merge operation. This would also allow us to do the conflict resolution interactively.

How has this been tested?

Added new unit tests.
Tested locally

src/core/Group.cpp

+    const QDateTime timeExisting = existingGroup->timeInfo().lastModificationTime();
+    const QDateTime timeOther = otherGroup->timeInfo().lastModificationTime();
+
+    // only if the other group newer, update the existing one.


missing "is" 😉

src/core/Group.cpp

+        existingGroup->setName(otherGroup->name());
+        existingGroup->setNotes(otherGroup->notes());
+        existingGroup->setIcon(otherGroup->iconNumber());
+        existingGroup->setIcon(otherGroup->iconUuid());


This will either reset the previously set iconNumber or trigger an assertion for !uuid.isNull(). You need to check which one is set: icon number or UUID.

@phoerious you're right, the tests we're indeed failing when building in debug mode. Which makes me think, should we not build in debug mode in travis?

We are building both in Debug and Release mode. I have no idea why the tests passed.

Wrong indentation

That's actually the formatting done by clang-format. How do you think it should be indented?

CloneFlags groupFlags should be on the same level as Group*

@phoerious still not sure what you mean. CloneFlags groupFlags, so it should be aligned with the other parameters.

Anyway, I extracted the default flags for the function, so the signature is much smaller.

I just got owned by the inline diff view. Ignore what I said. But not having a static_cast there is a lot cleaner, now, anyway.
