When accessing a ContentProvider that is unprotected by top-level
permissions, and caller doesn't hold a matching <path-permission>
permission, revoke the default top-level access.

This enables an otherwise unprotected provider to enforce permissions
on specific paths.

75ea64fc54f328d37b115cfb1ded1e45c30380ed 26-Jan-2012 Jeff Brown <jeffbrown@google.com> Implement a cancelation mechanism for queries.

Added new API to enable cancelation of SQLite and content provider
queries by means of a CancelationSignal object. The application
creates a CancelationSignal object and passes it as an argument
to the query. The cancelation signal can then be used to cancel
the query while it is executing.

If the cancelation signal is raised before the query is executed,
then it is immediately terminated.

d2183654e03d589b120467f4e98da1b178ceeadb 09-Oct-2011 Jeff Brown <jeffbrown@google.com> Fix ownership of CursorWindows across processes.
Bug: 5332296

Ensure that there is always an owner for each CursorWindow
and that references to each window are acquired/released
appropriately at all times.

Added synchronization to CursorToBulkCursorAdaptor to
prevent the underlying Cursor and CursorWindow from being
remotely accessed in ways that might violate invariants,
resulting in leaks or other problems.

Ensured that CursorToBulkCursorAdaptor promptly releases
its references to the Cursor and CursorWindow when closed
so they don't stick around longer than they should, even
if the remote end hangs onto the IBulkCursor for some reason.

CursorWindow respects Parcelable.FLAG_WRITE_RETURN_VALUE
as an indication that one reference to the CursorWindow is
being released. Correspondingly, CursorToBulkCursorAdaptor
acquires a reference to the CursorWindow before returning
it to the caller. This change also prevents races from
resulting in the transfer of an invalid CursorWindow over
the wire.

Ensured that BulkCursorToCursorAdaptor promptly releases
its reference to the IBulkCursor when closed and throws
on attempts to access the cursor while closed.

Modified ContentProviderNative to handle both parts of
the wrapping and unwrapping of Cursors into IBulkCursors.
This makes it a lot easier to ensure that the right
things happen on both ends. Also, it turns out that
the only caller of IContentProvider.bulkQuery was
ContentProviderNative itself so there was no need
to support bulkQuery on ContentProviderProxy and it was
just getting in the way.

Implement CloseGuard on CursorWindow.

the OOM level of the target process.

...Invalid index 0, size is 0 at
android.app.ActivityThread.performPauseActivity(ActivityThread.java:2326)

It looks like if an arrow key is dispatched between the time the
list view is told its data set has changed and it does the resulting
layout pass, we could try to move the position to a now invalid
index. This may prevent that from happening.

Also put in a better error message if saving state of a fragment
whose target is no longer in the fragment manager.

And fix a bug in PackageManager where we could return a null from
queryIntentActivities().

And add a new API to find out whether a fragment is being removed,
to help fix issue #3306021: NPE at
android.app.AlertDialog.getDefaultDialogTheme(AlertDialog.java)

Next, for new HC apps we can delay committing data to
storage until the activity is stopped.

Finally, use the new multi-threaded AyncTask executor in a few
places, so we don't have worked blocked by long-running tasks from
the application.

23fdaf6fb62a9b5154b2508916a21c678462c5d0 06-Aug-2010 Dianne Hackborn <hackbod@google.com> Add new ContentProvider for doing conversions to data streams.

This introduces basic infrastructure that should allow content
providers holding complex data to perform on-demand conversion
of their data to streams of various types. It is achieved through
two new content provider APIs, one to interrogate the possible
stream MIME types the provider can return, and the other to
request a stream of data in a particular MIME type.

Because implementations of this will often need to do on-demand
data conversion, there is also a utility intoduced in ContentProvider
for subclasses to easily run a function to write data into a
pipe that is read by the client.

This feature is mostly intended for cut and paste and drag and
drop, as the complex data interchange allowing the source and
destination to negotiate data types and copy (possible large)
data between them. However because it is fundamental facility
of ContentProvider, it can be used in other places, such as for
more advanced GET_CONTENT data exchanges.

An example implementation of this would be in ContactsProvider,
which can now provider a data stream when a client opens certain
pieces of it data, to return data as flat text, a vcard, or other
format.

This permits implementing interfaces which are faster than using
remote Cursors. It then uses it for Settings & SettingProvider, which
together account for ~50% of total ContentProvider event loop stalls
across Froyo dogfooders.

For fetching Settings this looks like it should reduce average
Settings lookup from 10 ms to 0.4 ms on Sholes, once the
SettingsProvider serves most gets from in-memory cache. Currently it
brings the Sholes average down from 10ms to 2.5 ms while still using
SQLite queries on each get.

8280c2b15f6875b2d387c05df23d264864eb9cd5 22-Oct-2009 Daisuke Miyakawa <dmiyakawa@google.com> Implement new MockContentProvider. Also make ContentProvider aware of the class.

Rename the old MockContentProvider to MockIContentProvider since it is
more appropriate name.

Detail:
Current developers inevitably depend on the backend used by ContentProvider,
which is useful but not ideal nor "testable" from the view of them.

Current MockContentResolver only accepts exact "ContentProvider" class, not
IContentProvider interface, since we want to hide "IContentProvider" while
the old MockContentProvider implements IContentProvider and as a result some
methods we want to hide may be exposed to the public SDK now and probably
for the future.

On the other hand, ContentProvider is not interface but an exact class
heavily depends on the internal logic and not suitable for external
developers to use for tests.

The new MockContentProvider introduces the mock implementation
for ContentProvider.
It extends ContentProvider, so "is" ContentProvider, but tries to avoid
depending on any backend System like IPC in Android, etc.
This should be useful from the view of application developers who do not
want to be confused with ContentProvider/ContentResolver backend
implementation "at all" and want to use MockContentResolver without
any other ContentProvider implementations tightly connected to the
external worlds.

This adds a new <path-permission> tag you can use inside of a <provide>
to define additional path-based permissions that broaden the global
read and write permissions. The initial use for this will be global
search, so that a content provider that is protected by permissions
can make a part of itself available to global search under another
permission. This addresses the issue with global search not being able
to request permissions it would need of providers it doesn't know
about at build time.
