See http://bugs.python.org/issue12904. Basically, we can get the mtime in
nanosecond precision, but only set it in microsecond precision. This means
that the shutil.copy2 will not set the destination's mtime to exactly the same
mtime as our source. The end result is that we can *always* end up copying
the extension because the source always appears newer. We add a microsecond of fudge time when checking to see
if the source is newer than the destination to get around this.
This bug is fixed in Python 3.3+, I believe.
move the strictness to our release script
this means others can build personal wheels without less, invoke,
but IPython releases still cannot be made without them,
which is the real goal.
- Adds a `GenericCheckpointMixin` as a helper for implementing the two
boundary-traversing Checkpoint API methods, `create_checkpoint` and
`restore_checkpoint`.
- `GenericFileCheckpointManager` is implemented as a subclass of
`FileCheckpointManager` using `GenericCheckpointMixin`. Note that
this is the safe subtyping relationship because of method
signature *contra*variance: `FileCheckpointManager` accepts
`FileContentsManager` in its method signatures type, whereas
`GenericFileCheckpointManager` accepts any `ContentsManager`.
- Moved Checkpoint-related classes to their own files.
js test are the longer ~8 minutes vs ~3 for Python, and fails the more often.
Hopefully this will speedup the build and have less test relaunched when we
have a random faillure. Splitting should make the js test a bit faster
On `create_checkpoint` and `restore_checkpoint`, pass a path and a
`ContentsManager` to `CheckpointManager` instead of an already-loaded
model.
The `CheckpointManager` base class provides a correct implementation of
these methods that's generic across any ContentsManager, but subclasses
are free to specialize when the storage backend of `ContentsManager` is
shared.
multiplex on a 'channel' key in message,
rather than separate websockets.
Unlike zmq, there aren't different message patterns that require the channels to be separate.
Reduces FD count by factor of 3 and connection complexity in js.
