[Bug]: InvalidateAll only removes objects without a type, does not clear the cache

[markuspalme]

Describe the bug 🐞

The documentation for InvalidateAll states that the method Invalidates all entries in the cache (i.e. clear it). (see

Akavache/src/Akavache.Core/IBlobCache.cs

Line 235 in 98baa39

/// Invalidate all entries in the cache (i.e. clear it). Note that

)

However, the implementation only removes entries where the TypeName is null:

var entries = sql.Table<CacheEntry>().Where(x => x.TypeName == null).ToList();

See https://github.com/reactiveui/Akavache/blob/98baa3926672bb0e62082ca97ffc058cad604b16/src/Akavache.Sqlite3/SqliteBlobCache.cs#L798C65-L798C88.

This is not clear from the documentation and I would expect all cache entries to be removed.

Step to reproduce

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior

The cache should be cleared completely.

I thought I was losing my mind when experiencing this same issue. This is quite confusing.

Interestingly, calling GetAllKeys doesn't return all keys of items in the cache, either.

Also experiencing this currently. InvalidateAll followed by a Vacuum, doesnt clear entries, and we keep on retrieving cached values after Invalidate.

Quite frustrating, have not yet found a workaround.

Edit:

Found a workaround that fits my usecase:

var userAccountKeys = await CacheDatabase.UserAccount.GetAllKeys().ToList();
if (userAccountKeys.Count > 0)
{
        await CacheDatabase.UserAccount.Invalidate(userAccountKeys);
}

Basically do the above for each CacheDatabase.
