couchbase-lite-net's Issues

Implement PCL support

Issue #5 provides an implementation plan, which is implemented in this issue.

ApiTest.TestSharedMapBlocks passes invalid parameter

View.SetMapReduce requires a non-null version parameter as the third attribute, but ApiTest.TestSharedMapBlocks passes null anyways. Should pass "1".

MultipartDocumentReader reports incorrect image hash

[Android] Should Replication.Changed Event Handler dispatched on the UI Thread?

Should Replication.Changed Event Handler dispatched on the UI Thread especially for Android?

Fix `foo == null` where `foo` is of an unconstrained generic type

Since unconstrained generic types can be System.ValueType, comparisons to null are invalid in those cases. Need to either constrain to class and add Nullable<T> support, or check for default(Foo) when !(Foo is ValueType).

Port ChangeTrackerTest from Android

Fix Unit Tests

I'm currently working on ApiTests, but there are lots of other test classes that need love.

Each one needs to be migrated eassentially from JUnit 3 to 4 in order to work with our current version of NUnit (attributes vs. Inheritance). Many of the NUmit methods also swap the ordering of the JUnit method params.

Then, cleanup the Java-like code to fit modern C# style. Verify the logic of the rest, then fix the library where tests fail.

View.ResultSetWithOptions throws assert on inappropriate key type check

Checks System.Diagnostics.Debug.Assert((minKey is string)); when minKey is usually an integer. Just a few lines later it calls ToJSONString(minKey) anyways.

Need to update the README markdown

1.0.0 Investigate Xbox support requirements

What is the work needed to expand our current support to include Xbox as well? May be trivial, but want to double-check to see if anything specialized is required.

Test runner log output is duplicated many times

ApiTest : Async Query Test Results are blocked

How to reproduce :
Run ApiTest.TestAsyncViewQuery() or ApiTest.TestLiveQueryRun()

As Query.RunAsync() called its completion handler via Database.Manager.CapturedContext.Scheduler(), the completion handler gets blocked from processing. This happens because the CapturedContext and the unit test are running on the same thread.

DatabaseTests.TestPruneRevsToMaxDepth fails

The test itself has an issue, as the numPruned should match 10, the value in the Java unit test.

Also, Database.cs:4061 still has embedded ? placeholders in the SQL fragment instead of the ADO.NET @ character.

iOS test crash: non-page-aligned, non-allocated pointer being freed

Non-deterministic behavior, but usually happens when running a large number of test sessions without resetting the local sync_gateway.

LiveQuery stops working on iOS Sample App

Steps to reproduce :

Create a couple of items
Check and Uncheck one of the items multiple times and fast until UI stops updating the checked status.

Initial Debug :

Even though the UI stops updating, the new revision of the document still gets created.
LiveQuery gets a Database Change event when updating the checked status of the document.
LiveQuery called Update() method to start re-querying the data by dispatching an asyc tasks to a WorkExecutor which is Manager.workExecutor but the async task has never run by the executor. As a result, the UI doesn't get updated with the new result set from the Live Query.

1.1.0 Port of Todo-Lite for Windows Phone

Replace all instances of `lock(this)`

To avoid potential deadlocks, replace lock(this) with a private lock object instead:

private readonly Object locker = new Object();
...
lock(locker)
{
      // Do foo
}

Add WebSocket support to replication

Investigate PS4 support requirements

There are related chores for this, including developer account set up, etc. but a general task to get started is for an investigation into requirements.

ChangeTracker not support POST requests

Based on Android implementation, ChangeTracker should also support sending POST requests to Sync Gateway.

Add continuous mode support to Puller

Implement Replication.SetCookie() and DeleteCookie()

Implement Replication.SetCookie() and DeleteCookie() to support cookie management.

[iOS Sample] Invalid update: invalid number of rows in section 0

After deleting checked items via the Clean button, the follow UIAlertView is shown:

The number of rows contained in an existing section after the update (10) must
be equal to the number of rows contained in that section before the update (10),
plus or minus the number of rows inserted or deleted from that section
(0 inserted, 9 deleted) and plus or minus the number of rows moved into or out 
of that section (0 moved in, 0 moved out).

CouchbaseTableSource.DeleteDocumentsAtIndexes throws this because after it calls TableView.DeleteRows the UIKit will call CouchbaseTableSource.RowsInSection during its consistency check.

ReplicationTest.TestGetReplication sometimes fails

When TestGetReplication runs by itself, or with the other tests in ReplicationTest it always passes. However, when running all 87 tests it always fails. When it fails, it fails because it calls replication.Stop() but replication.IsActive returns true.

Support for Windows Store, Phone and others

I would like to discuss the possibility of extending/converting the couchbase lite .net in order to support more platforms than xamarin.droid and xamarin.touch only. Currently the shared files depend on a number of namespaces, such as: System.Data, Mono.Data.Sqlite, System.Web, System.Threading, System.Security... which makes compiling these files with, for example, a windows 8(.1) (store) project impossible.

I think the proper architecture would be to define a PCL with the database functionality rewritten to use something like SQLite.Net-PCL/Async and HttpClient for networking.

Of course, this looks like quite some work, and it has the drawback that automated conversion from java would not be that easy anymore, if not impossible. I can invest some of my time in this, but will not do so if there is no support or interest from others... most notably couchbase.

Create simple UWP sample

Evaluate PCL Feasibility

The first consideration will be which profile to target.

Second, will need to consider how to manage the dependency on SQLite. We could move the MonoSqliteStorageEngine to a new Couchbase.Lite.Sqlite non-PCL assembly. However, we'd then need to provide a new default implementation in Couchbase.Lite. If we tried to source link community-sqlite-net, we'd not be able to target WP8 or WinRT (unless they've done a lot of refactoring since last June).

Options:

Default implementation just throws NIE and tells the user to add a real implementation.
Create shims that lets the WP8/WinRT variants of community-sqlite-net run on Xamarin.*.
Create shims that lets the Xamarin variant of community-sqlite-net run on WP8/WinRT.
Create a default implementation that avoids IO and some/all encryption, and or uses reflection to do it.
Not ship a PCL. As nice as PCL's can be, if may end up with a better user experience shipping non-PCLs, especially if not doing so means targeting a weird profile or requiring a bunch of extra steps for library users. The goal is "add package" and it just works.

Perhaps someone with deeper WP8/WinRT-fu can weigh in.
