    Inherit `MultiIndex` from `Index` only
    
    As `Index` already subclasses `Serializable`, there is no need for
    `MultiIndex` to subclass `Serializable` as well. Plus it seems to be
    confusing Python. So drop it.

    Use NumPy arrays for older pickle protocols
    
    Since `memoryview`s are not generally pickleable, coerce them to NumPy
    arrays, which are, when handling pickling with older pickle protocols.
    For pickle protocol 5+, stick with coercing them to `PickleBuffer`s,
    which pickle knows how to serialize out-of-band.

    Subclass cuDF objects from `Serializable`

commit df373535376e98c17fc7009ea4fe2af53c8ec633
Author: John Kirkham <jakirkham@gmail.com>
Date:   Thu May 7 23:50:25 2020 -0700

    Add the `Serializable` abstract base class
    
    This provides a generic interface for handling serialization in Python.
    Handles serialization with Dask through the `"cuda"` and `"dask"`
    serializers. Also implements pickle serialization using `__reduce_ex__`.
    For Python versions with support for pickle's protocol 5, the class also
    supports out-of-band buffers for more efficient serialization.
    Subclasses are responsible for implementing `serialize` and
    `deserialize` to/from a Python `dict` with the `header` and a collection
    of `frames`. The abstract base class handles all other serialization
    using these two methods.

    Note out-of-band buffers supported in pickling

commit cedf90a1d1860821d1e92a028bf942d13a4a25b9
Author: John Kirkham <jakirkham@gmail.com>
Date:   Thu May 7 13:31:31 2020 -0700

    Support out-of-band pickling when available
    
    In Pickle's protocol 5, out-of-band buffers are supported, which avoids
    unnecessary copies when serializing data. In other words, this similar
    to Dask's custom serialization except for pickling and can be supported
    by any library that can use this Python standard. The only requirement
    is we wrap any bytes-like objects in `PickleBuffer`s in our
    `__reduce_ex__` method, which is what we do here. If an older Pickle
    protocol is in use, we simply skip this path and go about pickling the
    NumPy array as we would have otherwise.

commit eeb3cc452ce51a4141c0ffbce46c8b5b5ed5adfa
Author: John Kirkham <jakirkham@gmail.com>
Date:   Thu May 7 13:31:30 2020 -0700

    Implement `__reduce_ex__` instead of `__reduce__`
    
    This lets us get access to the `protocol` argument, which can be useful
    if we want to take advantage of newer pickling protocols.

Date:   Mon Apr 27 14:47:05 2020 +0100

    Use RMM for Numba
    
    When cuDF is imported, it configures Numba to make all allocations from
    the RMM memory pool via RMMNumbaManager (similar to how the CuPy
    allocator is set to be RMM).
    
    References to RMM functions that re-implemented Numba functions are
    removed and replaced with calls to the Numba version - since Numba is
    now using RMM, the allocations will still come from the RMM pool.

    Fix Numba deprecation warnings with Numba 0.49+
    
    Many "internal" parts of Numba were moved with the release of 0.49.
    The old module locations can still be imported with a shim for the 0.49
    release, but its use results in the emission of NumbaDeprecationWarning
    messages. The shims will be removed in Numba 0.50.
    
    This PR avoids the deprecation warnings and enables import from the new
    module paths where available, so that cuDF can be used with Numba 0.48,
    0.49, or (a future release of) 0.50.
    
    Once Numba 0.49 or above is a cuDF requirement, the `try .. except
    ImportError` blocks can be replaced with imports exclusively from the
    new locations.

    Hi!
    
    When following the setting up environment guide (https://github.com/rapidsai/cudf/blob/branch-0.14/CONTRIBUTING.md#setting-up-your-build-environment), pre_commit package cannot be found.
    
    I have added the channel conda-forge in order to help its resolution.
    
    Hope it helps!
    
    Regards,
    Miguel

    Rolling Window: Support DESC timestamps (JNI changes)
    
    This change adds JNI support, to compute time-range based
    rolling window aggregations on columns sorted in decreasing
    order of the specified timestamp column.

commit a3091b692899ddd9f2c3e934c889d9069eb16d19

Date:   Fri Apr 24 14:56:53 2020 -0700

    Rolling Window: Support DESC timestamps (c++ changes)
    
    In grouped_timestamp_based_rolling_window(), it is possible that
    the aggregated column is sorted in decreasing order of the accompanying
    timestamp column. The current implementation assumes ascending order,
    and returns the wrong results in this case.
    
    This commit adds support to allow the caller to choose the sort-order
    for the timestamp column.

    Removed comparison operators from list_view.  These will be handled as a seperate PR down the line. Added
    type trait is_equality_comparable.  Added SFINAE using is_relationally_comparable and is_equality_comparable to
    short circuit various pieces of cudf that were using the list_view operators.

    - max/min binary operator that considers null values
      - this is a superset of #4880
      - this adddresses feature request 3762
      - return max/min of 2 values such that:
        - min/max(x, null) || min/max(null, x) retruns x
        - min/max(null, null) returns null
        - min/max(x, y) returns the min/max value between x and y
        - this also works for string types (as long as the operands are stirng as well)

    Return the result of `to_json`
    
    When no path is given to `to_json`, it serializes the data to a string
    (rather than a file). However, this string is lost to the void because
    the result of the underlying call to pandas is ignored.

    Fix import errors with Numba 0.49+
    
    Numba 0.49 removes the vendored six library. This commit removes the use
    of six in applyutils, which is no longer necessary when supporting only
    Python 3. The replacements are:
    
    - `exec_` from `numba.utils` is replaced with `exec`.
    - `six.integer_types` is replaced with `int`

    Raise a `CUDADriverError` in `deviceGetName`
    
    As we are working with a driver API function and not a host API
    function, raise `CUDADriverError` instead of `CUDARuntimeError`. This
    should handle the differences correctly and relay them to the user.

commit 597b4986626b0bf6fa25e5008b8dc6b9b669f71e
Author: John Kirkham <jakirkham@gmail.com>
Date:   Fri Apr 17 21:28:26 2020 -0700

    Add `CUDADriverError` for driver errors
    
    As driver errors need to be handled a bit differently, add a separate
    class to handle that case.

    Decode C `char*`s directly to Python `str`s
    
    Since we really don't want to work with these as `bytes` objects in
    Python and converting them to `bytes` and then calling `decode` incurs a
    copy and extra work, go ahead and just decode the C `char*`s to Python
    `str`s directly and use them. Makes other code involving these values
    easier to work with.

commit 3212e3cce696835acd335b0888c35b8b6a7a8d94
Author: John Kirkham <jakirkham@gmail.com>
Date:   Fri Apr 17 21:28:23 2020 -0700

    Type `CUDARuntimeError`'s `status`
    
    Since we know `status` should be a `cudaError_t` value and we can
    enforce this in the constructor (as Python `int`s will be coerced to it
    as needed), go ahead and do that once at the outset. Should be cheaper
    to do once and then easy to reuse in simple/fast C++ code later.

    Fix return types of CUDA functions
    
    As these functions don't return `int`, but instead return of two `enum`s
    depending on whether they come from the device or host APIs, fix their
    declarations accordingly.

Author: John Kirkham <jakirkham@gmail.com>
Date:   Fri Apr 17 19:47:47 2020 -0700

    Allocate `device_name` on stack
    
    Instead of calling `malloc` with an unmatched `free`, just allocate
    memory on the stack. It will be faster to work with and we can rely on C
    to clean it up when we leave this scope.

commit a794910b387d430010a4fb01dae045d4fccbdcc6
Author: John Kirkham <jakirkham@gmail.com>
Date:   Fri Apr 17 19:47:46 2020 -0700

    Type `status` in `deviceGetName` as `int`
    
    Since the return value is already a C typed value, this just simplifies
    working with it in other C/Cython code. After all Cython will convert it
    to a Python `int` once that is needed (which should only happen during
    exception handling).

    Multiple binops fixes:
    
    - Changed binops jit code to use std::common_type for casting operands to fix issues with
    losing precision.
    
    - Fixed CPU-side verification code (ASSERT_BINOP) to use epsilon checking for floating point
    types instead of direct comparison.
    
    - Fixed CPU-side binops operation code so that it takes TypeOut into account when using common_type. It
    was only using the left and right operators so it missed the upcasting precision case.
    
    - Changed the way BinaryOperationTest test fixture works for generating random numbers.  Previously
    it was always using a generator of type uint8_t and then casting to output results.  This had the
    quiet problem of always generating whole numbers, which was defeating a number of the floating point
    tests.
    
    - Added several new binops test to trigger precision-sensitive tests that were missing.
    
    - Changed UniformRandomGenerator to use the 64 bit std mersenne twister random number generator.  Previously
    it was using std::random_device, which was also a mersenne twister, however, it was using a random seed so
    results between different runs of tests weren't repeatable.  Also changed it to use an incrementing seed
    value for each new UniformRandomGenerator created - without this, every "randomly" generated column would
    be the same values, which defeats most of the binops tests (for example, every mod test results in a value
    of 0).

    - support timestamp diff via binaryop
      - this is similar to the datediff sql function

    Include frame lengths in Dask serialized header
    
    As going through `"dask"` serialization can result in data being split
    for better compression, ensure the original number of bytes in the frame
    is stored in `header["lengths"]`. That way on `"dask"` deserialization
    the frames can be merged back into their original sizes before `"cuda"`
    serialization is performed.

    Added support for single->multi and other non-trivial case mappings. Added code

    of concept.

    fix Frame._concat libcudf++ nvtx cython calls

commit 6abeb930bea6b35e6b5df8a8a4283113daa3676b
Author: John Kirkham <jakirkham@gmail.com>
Date:   Wed Mar 18 15:27:01 2020 -0700

    Register `CategoricalDtype` for Dask serialization
    
    Appears we implement the `serialize` and `deserialize` methods for
    `CategoricalDtype`. However we were not registering it for efficient
    host and device serialization with Dask. So this adds it to the list.

    Note Dask serialization registration of `*Index`

commit 08f2099f9fe701826fef5a7514d323c1e4eabe13
Author: John Kirkham <jakirkham@gmail.com>
Date:   Wed Mar 18 14:48:53 2020 -0700

    Register `Index` and `MultiIndex`
    
    These already have the `serialize` and `deserialize` methods to enable
    serialization with Dask. However they were not being registered before.
    So go ahead and register them to allow for efficient serialization of
    them.

Date:   Wed Mar 18 14:48:52 2020 -0700

    Drop duplicate registration of `Series`
    
    We already registered this before by using the class from the top-level
    namespace. So drop the reference to it in its module.

    INT32 to data_type size_type

commit 70492157ad83bf8b74a6843afa938d254ea39bce

    Optimize `__reduce__` in `StringColumn`
    
    Instead of converting the data to arrow in `__reduce__`, simply follow
    the same pattern we are using serialize. This should allow for a pretty
    efficient pickling method when pickling of `StringColumn`s is required.

    [REVIEW] Make scalar destructor virtual.

commit a55eec8ed4e3b529d60ac57919fd3a723c5d5b29
Author: John Kirkham <jakirkham@gmail.com>
Date:   Tue Mar 10 22:52:45 2020 -0700

    Check device/host objects are received as expected
    
    When deserializing cuDF objects from Dask, make sure to check that
    frames are on device (by checking for `__cuda_array_interface__`) when
    `"cuda"` serialization is used and that frames are on host (by coercing
    them to `memoryview`s) when `"dask"` serialization is used. If these
    things don't work, make sure we raise an error. This would indicate the
    data was not transmitted as expected, which would be a bug and would
    indicate an unexpected performance degradation has occurred.

commit 58d6b7c00c3174428c300909ca737b0dada16e93
Author: John Kirkham <jakirkham@gmail.com>
Date:   Tue Mar 10 22:52:43 2020 -0700

    Serialize everything with CUDA first then run D2H
    
    To simplify the code paths a bit, this just dispatches to
    `cuda_serialize_cudf_object` at the beginning of
    `dask_serialize_cudf_object` instead of calling `.serialize()`. This
    ensures any checks we perform on that result are also performed in the
    host serialization path. Also makes it a bit clearer that host
    serialization is just device serialization followed by a device-to-host
    transfer.

commit c21157102b3cecfd8dface85e7d553ebaa8cd83a
Author: John Kirkham <jakirkham@gmail.com>
Date:   Tue Mar 10 22:52:41 2020 -0700

    Check that we are sending only `Buffer` objects
    
    As some classes like `CumlArray` are subclasses of `Buffer` and may not
    behave right when calling `.to_host_array()`, make sure we are only
    transmitting `Buffer` objects exactly. Since `CumlArray` already turns
    its self into a `Buffer` object, this should work fine in that case.
    Just should protect us if things get looser down the road.

    Use `uint8` type for host array copy of `Buffer`
    
    To match the type used for device arrays viewing `Buffer`, also use
    `uint8` for host arrays created from `Buffer`. This also matches the
    type of `bytes` and `bytearray` in Python.

Date:   Sat Feb 15 14:03:00 2020 -0800

    Add Buffer "constructor-kwargs" header
    
    Part of `Buffer`'s serializers' work includes handling subclasses (like
    cuML's `Array`). However it doesn't handle any keyword arguments those
    subclass constructors may need. This changes that by adding an optional
    (by default trivial) "constructor-kwargs" header. Subclasses can then
    call their parents' serializer and pack this header with relevant
    content afterwards. This way during deserialization this content can be
    passed into the subclass' constructor.

    Assert Dask CUDA serializers have `Buffer` frames
    
    Previously this was being `assert`ed in the Dask serializers. However we
    want to make sure we are passing `Buffer`s and not constructing other
    objects (like Numba's `DeviceNDArrays`) in CUDA serializers as well. So
    go ahead and move this to CUDA serializers where it still also affects
    Dask serializers.

    Add Dask serializers for cuDF objects
    
    In the event that serializing CUDA objects directly is not possible,
    this performs the next best thing, which is to serialize objects using
    Dask's serialization protocol. The protocol requires that data be on the
    host in 1-D contiguous `memoryviews`. So we perform serialization as we
    otherwise would. As a last step we perform a device-to-host transfer of
    the frames. Then we hand this off to Dask to serialize. When
    deserializing the data, all of the deserializers already work as frames
    are turned into `Buffer`s, which perform a host-to-device transfer if
    needed. This provides us an option that avoids pickling. As a result we
    are able to serialize things with Dask more efficiently using this
    protocol.

    Use "type-serialized" for pickled types like Dask
    
    Dask uses the "type-serialized" header to store pickled type
    information. Not to mention the "type" header is often used by Dask to
    mean something different. As a result Dask could potentially stomp on
    the information we are storing in the "type" header. So instead of
    deviating from Dask, just store the pickled type information in
    "type-serialized" as well. This should make it easier to more tightly
    integrate our serialization with Dask's down the road.

    More updates to column_accessor

commit 08e5a8f17972a1b1cb387b33d5ed188823f6a6b6
Author: John Kirkham <jakirkham@gmail.com>
Date:   Tue Feb 11 08:20:02 2020 -0800

    Use `nvstrings` directly in `sum`
    
    Since this `nvstrings` is memoized once used, it should be fine to just
    call it directly when it is needed. So do so in `.sum(...)` as well
    instead of relying on the internal `_nvstrings`, which may not exist
    yet.

Date:   Mon Feb 10 17:23:30 2020 -0800

    Special case handling of 0-size `StringColumn`s
    
    As it is possible to have no `children` when a `StringColumn` has
    0-size, we cannot always index `children`. So check if we have such a
    case and if so simply return `0`.

    Update Changelog entry (given recent changes)

commit 27c9c193b71512d149e17bd30e2c3755a7cb5bf3
Author: John Kirkham <jakirkham@gmail.com>
Date:   Mon Feb 10 13:50:45 2020 -0800

    Get `len` of `StringColumn`s without `nvstrings`
    
    It turns out we already have the information needed to determine the
    number of strings stored without needing to call the `nvstrings` API. So
    extract this information from the offset `Buffer` instead.

    Cosmetic Item #5: Replace protobuf lengths literal constants with constexpr

commit 681c9a235603f533d490ac2b86197c18b67630eb
Author: John Kirkham <jakirkham@gmail.com>
Date:   Mon Feb 10 13:32:39 2020 -0800

    Rewrite `StringColumn` to serialize internals
    
    Instead of relying on the `nvstrings` API to build a `StringColumn` at
    the other end, which may be expensive, go ahead and serialize the
    internal columns correctly and rebuild them on the other side. This
    avoids a bunch of unneeded copies when reconstructing the
    `StringColumn`. Also it allows us to skip calling `nvstrings` until it
    is actually needed.

    Fix to DataFrame indexing logic

commit d0ecea4f679ee880e858f696b2708dbfa3fd06bf
Author: John Kirkham <jakirkham@gmail.com>
Date:   Mon Feb 10 12:27:40 2020 -0800

    Use existing `Buffer`s for serialization
    
    As we already have `Buffer`s allocated with the relevant data, just use
    them in serialization instead of creating new ones. Also it is worth
    noting offsets come first and then strings. However deserialization
    expects the opposite order. So make sure to reverse the children before
    adding them to the frames to match that expected order for
    deserialization.

    Construct `Buffer`'s to serialize `StringColumn`
    
    As `Buffer` objects are faster and lighter weight to construct (not to
    mention the future of handling data in cuDF), construct `Buffer` objects
    to hold the relevant string content. These can then be added as frames
    to send with Distributed and UCX-Py since they know how to ship them.

    Handle `Buffer` subclasses during deserialization
    
    As it looks like there will soon be subclasses of `Buffer` like cuML's
    `Array`, make sure to handle serialization of subclasses as well. This
    is done by including the pickled class `type` in the header. That way
    cuDF's serializers will store information about the subclass type during
    serialization, which can restore after deserialization.

Author: John Kirkham <jakirkham@gmail.com>
Date:   Fri Feb 7 17:52:43 2020 -0800

    Add `__len__` and `nbytes` to `Buffer` for Dask
    
    Dask tries to figure out the length and/or number of bytes in a given
    object before sending the object itself so the receiver can allocate
    some space to fit this data. It does this by using `len(...)` and
    checking the `.nbytes` property. Since we are trying to now send
    `Buffer`s direct through Dask. Make sure they also have these methods so
    that Dask is able to inspect their size before sending them.

    Use `Buffer` serialization in `ColumnBase`
    
    As we are now able to serialize `Buffer`s directly, this leverages their
    serialization to fill out the associated headers and convert them into
    frames that can be sent over the wire.

    Provide serialization methods for `Buffer`
    
    Instead of creating Numba `DeviceNDArray`s, these serialization methods
    supply a way for `Buffer` objects to ship themselves directly. This
    should help avoid overhead caused by building Numba `DeviceNDArray`s.

    All null string entries should have null data buffer

commit b3f7a6de18209b3fd065fb2b69e2c5365d62a8b8
Author: Dave Baranec <dbaranec@nvidia.com>
Date:   Wed Feb 5 15:46:53 2020 -0600

    First pass of parquet write_chunked support,  PRE-commit.  To make seeing key diffs easier I'm committing this change with the bulk
    of writer::impl::write() moved into writer::impl::write_chunked() but without any of the internal changes.  The next commit will
    have all the actual logical changes.  Hopefully makes PR reviews easier.

Author: Dave Baranec <dbaranec@nvidia.com>
Date:   Mon Feb 3 11:31:33 2020 -0600

    Changed code that computes column split information to retrieve offsets from the gpu to the cpu (single kernel call per split) and then compute the split
    information in-place on the cpu.  This also allows us to toss the non-throwing versions of bitmask_allocation_size_bytes and round_up_safe.
    
    Change column collection code to just use a simple for_each that directly checks for strings instead of type dispatching and doing nothing for non-strings.
    
    Several other small PR review changes.

    Simply build `Buffer`s from each frame
    
    As the `Buffer` class handles all of this logic and gives us something
    that we can easily build higher level cuDF objects, just create
    `Buffer`s directly from these `frames`. Then extract the pointers from
    these and pass them to `nvstrings.from_offsets`.

    Move bitmask_allocation_size_bytes_nothrow to better location -> detail/null_mask.hpp bitmask_allocation_size_bytes_nocheck.
    Created round_up_pow2() (used for aligning allocation sizes) that's more optimal if you're using alignment values that are a
    power of 2.
    
    Change several fields in column_split_info from size_type to size_t to dodge potential overflow issues.
    
    Some brief description changes.

    Fix string serialization and memory_usage method to be consistent

commit 76273579fffc0c422b9581c62526b53004b448dc

    Note changes to `Buffer` data handling

commit 7e15bde0611bfe74adebc8404425fa31c01acb60
Author: John Kirkham <jakirkham@gmail.com>
Date:   Tue Jan 28 14:25:29 2020 -0800

    Try to create a `memoryview` of any data
    
    Instead of merely check to see if a `memoryview` was passed to us, go
    ahead and try to construct one from `data`. This should help coerce
    anything that supports the Python Buffer Protocol (like `bytes` and
    `bytearray`) into a `memoryview`, which we can easily construct a host
    array from. Should be simple to create a device array from there.

commit ab46f28ddeace7eeb7077f26590bc0e7222fe766
Author: John Kirkham <jakirkham@gmail.com>
Date:   Tue Jan 28 14:11:20 2020 -0800

    Reorganize `data` type checks and exceptions
    
    Turn the unexpected `data` type case into a flat out exception. Make a
    case for `data` being an address where `size`'s type is also checked.
    Should make this a bit clearer on what the cases are and when the
    exceptions occur. Also should simplify the process for adding new type
    cases.

    Numerous small PR review changes.
    
    Use std::transform() instead of a for loop in BM_contiguous_split. Added a lot of internal function documentation. Bumped
    contiguous_split() allocation alignment/padding to 64 bytes to conform with Arrow standard. Use a std::transform() instead
    of a std::for_each() in table_view version of slice. Renamed some tests. Removed column_view operator from
    contiguous_split_result and refactored some test code accordingly.

    Override `CategoricalColumn.__cuda_array_interface__`
    
    The definition of `__cuda_array_interface__` in `TypedColumnBase`
    doesn't make sense for `CategoricalColumn`. So override
    `__cuda_array_interface__` in `CategoricalColumn` to address this issue.

    Note serialization improvements

commit 663ba7263db187d51943416794d49351b4517b61
Author: John Kirkham <jakirkham@gmail.com>
Date:   Tue Dec 10 00:33:10 2019 -0600

    Use `__cuda_array_interface__` for serialization
    
    Leverages Numba to coerce an object using `__cuda_array_interface__`
    into a `DeviceNDArray`. This is what is done for `memoryview` objects as
    well. Should also make later steps that expect a `DeviceNDArray` work.

commit de2f379dee0a640fbe0ebb546bf372c8d8aa5b2a
Author: John Kirkham <jakirkham@gmail.com>
Date:   Tue Dec 10 00:15:02 2019 -0600

    Use `np.asarray` in `StringColumn.deserialize`
    
    Instead of using `np.frombuffer`, which is a bit unwieldy (like it loses
    type information), use `np.asarray`, which can take a `memoryview`. This
    way type information is preserved without needing to hack it back in
    afterwards. Should make the code a bit easier to follow as well.

    Cleaned up and refactored contiguous_split().  Added benchmarks and tests for contiguous_split().
    
    Added table_view overloads for slice() and split(). Added appropriate tests.
    
    Fixed a bug in CMakeLists.txt for iterator_bench.  Although I think this may be in an old/inappropriate place and might
    need to be moved entirely.

    Use `__cuda_array_interface__` for serialization
    
    Leverages Numba to coerce an object using `__cuda_array_interface__`
    into a `DeviceNDArray`. This is what is done for `memoryview` objects as
    well. Should also make later steps that expect a `DeviceNDArray` work.

    Use `np.asarray` in `StringColumn.deserialize`
    
    Instead of using `np.frombuffer`, which is a bit unwieldy (like it loses
    type information), use `np.asarray`, which can take a `memoryview`. This
    way type information is preserved without needing to hack it back in
    afterwards. Should make the code a bit easier to follow as well.

    Include `strides` in `__cuda_array_interface__`
    
    As some implementations of `__cuda_array_interface__` expected `strides`
    to be filled, go ahead and provide the `strides` field. As we ensure the
    data is contiguous, we know the step size is just the size of the item
    in the columns. Additionally we know columns are 1-D. So just make the
    `strides` a singleton `tuple` with the item size.

commit d6330e8b2a63da46503b6c849431f266049a4b3a
Author: Dave Baranec <dbaranec@nvidia.com>
Date:   Sun Dec 8 16:25:43 2019 -0600

    Rough draft of a simple contiguous_split function.  For N columns and M splits it involves O(M) allocations
    and O(N*M) kernel calls.  Potential optimization are custom kernels that copy either by split subtable or
    potentially even doing the whole thing in one shot.

    COUNT rolling aggregations always produce INT32 output columns

    PR comment fixes and string test fixes

    on a string column table and the result (including nulls) is as
    expected.

    [REVIEW] Port unary cast to libcudf++

commit ceb5de8973188bdd69e78d041efce6f526aabc0d
Author: Dave Baranec <dbaranec@nvidia.com>
Date:   Mon Nov 25 13:27:53 2019 -0600

    Add a new overload of allocate_like() that takes type, size and mask_state as individual params instead of deriving them from
    an existing column.  The use case for here is something like:
    
    out = copy_if_else(scalar, scalar, column boolean_mask)
    
    where the type is dictated by the scalar inputs, but the size is dictated by the boolean_mask column.

Author: Dave Baranec <dbaranec@nvidia.com>
Date:   Tue Nov 19 15:54:28 2019 -0600

    unsigned int) to roll negative which would prevent us from every bailing early.

    Rename some variables to not be quite as shorthand (w_ -> warp_) and eliminated some redundancy in cases where 'warp' is implied.
    
    Fixed an issue where missing parentheses could result in us reading off the end of input data.
    
    Added a special test case which sends in data that does not fit within the grid.  64 elements, grid size of 32.  This force
    tests the loop indices warp_cur and index in the grid stride loop.

    Removed the requirement for both input columns to have the same nullability.  Fixed an incorrect parameter ordering in
    the detail::copy_if_else declaration.  Add __launch__bounds__ optimization to copy_if_else_kernel. Fixed indexing bug
    in the grid stride loop.  Removed several unnecessary has_validity checks.
    
    Fixed issue where the code was only updating the null count in the mutable column view and not the output column. This issue
    was masked by the way column::mutable_view() quietly invalidates it's own internal count, causing a silent recompute the
    next time null_count() is called.
    
    Changed tests to use all fixed-width types instead of numeric types. Replaced the must-have-same-nullability test with one
    where mixed nullable/non-nullable columns are used.

commit c22c2ee313a26e0e98ace2564c03f57f94ed7eab

    Change null/valid counting logic in copy_if_else kernel to be more similar to the traditional method as in valid_if.
    
    Flipped the logic in the kernel from counting nulls to counting valids, which makes the internal logic simpler and
    more similar to other examples in cudf.
    
    Switched to using an rmm::device_scalar for passing valid_count in/out of the kernel rather than hand allocating and
    memcpying.
    
    Added a number of new tests.

    Replace invert_map with column_scatterer
    
    Gather does not support in-place operation, so the old approach of using gather with an inverted scatter map no longer works. Instead use thrust::scatter per-column.

    Add an addition check to make sure either : both incoming columns have a validity mask or neither do.

commit b67d835c30f6dcb7a6f4c2f45b657c1a8801e014
Author: Dave Baranec <dbaranec@nvidia.com>
Date:   Tue Nov 12 18:10:50 2019 -0600

    Reimplemented copy_if_else as a single kernel that does the copy logic itself and updates the validity mask for the
    output column.  Modelled after copy_range.
    
    Moved Filter parameter to be after the input columns to be consistent with other copy_* functions. Moved the
    boolean_mask parameter for the explicit version as well.
    
    Improved/expanded the tests for copy_if_else, including columns with validity masks.

    Merge branch 'branch-0.11' of github.com:rapidsai/cudf into fea_ext_port_filling_part1

commit f21b4ec95540cf4a188abc24d06f301b6d629f37
Author: John Kirkham <jakirkham@gmail.com>

    Use `asarray` to coerce indices to a NumPy array
    
    Calling `np.array` on a NumPy array will cause a copy. This can be
    avoided by calling `np.asarray`, which will preserve an existing array
    when passed in.

commit fdeb5381d26dabc9b7c19d1185b4cbdcac4e6001
Author: Jaime Ieong <jieong@nvidia.com>
Date:   Tue Oct 1 16:26:11 2019 -0700

    BUG: Fix idle GPU time due to unnecessary host vector default init
    
    * Use `thrust::host_vector` to perform assign from device_vector
        - `std::vector` default inits row offsets on instantiation
        - the default init can be a long time for many rows
    * Call `column.finalize()` for final setup of columns

    * Parameterization of the behavior when comparing two invalid values
    * Now using `cudf::is_nullable()` when relevant
    * No longer assuming the same non-nullability
    * Using `unwrap()` by default in `detail::to_string()`, since unwrapping non-wrapped type is an idempotent operation.

    merge: revert `cpp_join.join()` to accept the `on` argument
    
    Since we do not support different named columns in `left_on` and
    `right_on`, there is no use for two separate arguments.
    Instead we will only have an `on` argument.

commit 9f5b0476eaa7b7edb151641c0290ad248d7ebee4
Author: Tadahito Kobayashi <takobayashi@nvidia.com>
Date:   Thu May 30 13:54:49 2019 +0900

    add __host__ to device operators
    
    The device operators (cudf::DeviceSum, etc) only had __device__ function operator.
    changed `__device__` -> `CUDA_HOST_DEVICE_CALLABLE` (__device__ __host__ inline)
    
    Then, use cudf::DeviceSum for iterator test.

    [DOC] Updates for branch-0.7

commit 34497670b2fd261fba43d78afe6f02c22640a46b
Author: Devavret Makkar <dmakkar@nvidia.com>
Date:   Fri May 10 01:03:20 2019 +0530

    Made the mutexes static.
    Because the cache class is allowed to be used as non singleton. The file cache access should still be limited to one thread per process. The lockf locks can prevent multiple processes from accessing the file but are ineffective in preventing multiple threads from doing so as the lock is shared by the entire process.

Author: Devavret Makkar <dmakkar@nvidia.com>

commit 8aae2318fbdf1e13e75462264a27d6fdde84e704
Author: Mark Harris <mharris@nvidia.com>
Date:   Mon May 6 01:38:19 2019 -0700

    Modify apply_boolean_mask code to use bit_mask_t and bit_mask::is_valid. Fix test failure due to commented out cudaMemset. Remove null check from bitmask::is_valid because it hurts performance when checked by every thread in a kernel. Update rolling kernel to check for null valid pointer outside of is_valid.

    Replacing `cudautils.gather`

    Except for `Index.take()`, `Column.take()`, `Series.take()`,

commit cdeac439edb7b5d90c661dbfe0aa26f976121e61
Author: Eyal Rozenberg <eyalroz@technion.ac.il>
Date:   Sat Feb 9 00:10:58 2019 +0200

    Fixes #1160 + A bit of testing code cleanup:
    
    * Reversed include orders - see issue #681; this exposed some missing includes, so:
    * Added missing includes, especially for standard library headers, to some test programs (and some non-test utility headers)
    * Moved some non-inlined, non-template test utility code from headers into actual source files (so that it doesn't get defined twice)
    * Replaced `types.h` uses of `stdint.h` types with the raw types, under the same assumptions as for `gdf_date32`, `gdf_date64` etc.
    * Minor changes to the column printing code

Author: takobayashi <takobayashi@nvidia.com>
Date:   Tue Feb 26 16:46:45 2019 +0900

    Minor bug fix and update from feedback
    
    - bug: move "copy null bitmask" outside of "if(input_has_nulls)" block
       otherwise, output nulls are not updated if intput->null_count == 0.
       at least outtput->null_count = 0 is required.
    - update prefixsum API doxygen
    - doxymentation for `copy_and_replace_nulls`
    - remove unused declaration `using cub::DeviceScan`
    - fix GDF_REQUIRE usage for calling `scan_function`

    Avoid custom Dask serialization
    
    Previously cuDF was clever about passing around IPC handles through dask
    serialization that would then set up a side-channel communication using
    more advanced comm technology.
    
    Unfortunately this code became stale and now seems to be producing wrong
    results.  See https://github.com/rapidsai/dask-cudf/issues/90
    
    In the future we plan to use UCX-Py to handle inter-node and inter-GPU
    communication, which will remove the need for this IPC handle approach.
    For now we remove this custom code so that we at least get correct
    results, even if they are slower than we would like.

    FEA Add Series digitize method
    
    Add `digitize` method to `Series` class that
    mimics Numpy's `digitize` but does not
    check for monotonicity of input bin values.
    
    Expose `gdf_digitize` in `libcudf` to do the
    work on the backend.
    
    Transforming continuous valued features into
    discrete ones is a common data processing step
    in many machine learning models. The `digitize`
    method allows the user to do just this if they
    have, say, the histogram bin boundaries of a
    continuous feature column.

    Improve groupby indexing support
    
    - Change default to as_index=True to match pandas
    - Change `cudf` as_index NotImplementedError to a warning, so I don't
      have to
      modify _every_ test.
    - Remove the multi-aggregation column prefix when multi-aggregation is
      not used
    - Implement __getitem__ and __getattr__
    - Implement UnaryIndex - that is, if as_index is set and `by` is length
      1,
      convert that column into the df or Series index
    - Return a Series when as_index, `by` is length 1, and 1 other column
      exists
    - Create indexing tests as requested by @mrocklin
    - Pass all tests
    
    Formatting:
    - Default dataframe to 2 column tabs
    - Add name and dtype to Series output
    - Format Dataframe and Series nicely

    FEA Add hash encoding series method.
    
    The method `hash_encode` has been added to the
    `Series` class to allow the user to encode
    the series' values into a bounded, non-negative
    range using a hash function. Furthermore, the
    user can also optionally combine the hashed
    values with the hashed value of `Series.name` in order
    to (most likely) obtain different encoded values
    for the same original value in different columns.
    
    A parameter had to be added to the `gdf_hash`
    function to allow the caller to combine hashed
    column values with a user specified ones.

    [REVIEW] Fix CMake race condition for NVStrings

commit 6e1bdb38fd2f8271b33201f157c0de6d9d2ffd9e
Author: Andrew Foote <afoote@nvidia.com>
Date:   Tue Jan 22 22:18:37 2019 -0800

    Specialize update_existing_value for sum_op
    
    Hardware atomic addition is much faster than atomic addition via CAS,
    since it can be performed in L2. This change specializes the implementation
    for update_existing_value for the sum_op aggregator for int32, int64,
    fp32, and fp64.
    
    In my test on a GP102, the time to compute a groupby mean
    on 10M entries with only 10 distinct groups improved from
    ~3.7s to ~60ms.
    
    [Helps a lot with #533.]

commit eddee1a30b35e6d0cb92ec5939b20007c4cb70e7
Author: Matthew Rocklin <mrocklin@gmail.com>
Date:   Tue Dec 18 11:36:18 2018 -0800

    add undefined is_monotonic attribute to Index
    
    This attribute is used in some algorithms to be faster when the index is
    known to be sorted.  In our case we don't care to signal this because
    those algorithms are unlikely to be faster on the GPU.  We don't mind
    doing the full-pass algorithms every time.
    
    However, this may also confuse users, who might check this and assume
    that their index is not sorted, even if it is.  I've gone with the value
    `None` here sometimes used with ternary logic to signify that we're not
    making a claim either way.
    
    This is used by dask.dataframe when doing repartitioning.

Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Fri Nov 16 13:37:54 2018 -0800

    Updated type_dispatcher to invoke template instance by passing a traits structure templated on a gdf_dtype instead of a C++ datatype.
    This changes allows a one-to-one mapping between gdf_dtypes and template instantiations of the functor template that is invoked by the dispatcher. This ensures that one can specialize a template to uniquely handle any of the gdf_dtypes without ambiguity.

Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Thu Nov 15 10:35:43 2018 -0800

    Added new C++ type definitions for the non-primitive gdf_dtype types.
    These type definitions were added in order to allow distinguishing between gdf_dtype enums that map to the same underlying primitive type.
    For example, this is necessary if one wishes to specialize a functor invoked via the gdf_type_dispatcher to handle GDF_CATEGORY differently from GDF_INT32.

Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Wed Sep 5 15:32:49 2018 -0700

    Fixed the use of the int_fastdiv modulus operator. Two problems: First, int_fastdiv casts the dividend to an int, which if the dividend was originally an unsigned type can result in negative modulos. Second, because of the casting, int_fastdiv operator% can return different modulos than using the normal % operator.

Date:   Thu Aug 16 11:02:18 2018 -0700

    Hash Join for arbitrary number of columns
    
    - Added gdf_table which inherits from managed class to be allocated with managed memory.
    - Implemented a hash_combine function to combine two hash values.
    - Refactored the join_hash function to operate on gdf_tables.
    - Eliminated the InnerJoin and LeftJoin functions in favor of a single compute_hash_join function. Refactored the API to operate on gdf_tables.
    - Added size_type as a template parameter to unordered_multimap.
    - Updated the signature of the probe_hash_table function to work with new gdf_table structure.
    - Added commented to probe_hash_table_uniq_keys kernel to indicate that it still needs to be updated to work with an arbitrary number of columns.
    - Added date and timestamps for joins.

This value is only used during the hash table initialization, and therefore moving it from a compile time to runtime constant should have no performance impact."

Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Wed Jul 11 13:23:13 2018 -0700

    Expanded comments for the new insert with aggregation and updated for readability.

commit 80f755a15fcb0272d8f2752fc90e052aa8e7d01d
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Tue Jul 10 17:24:28 2018 -0700

commit e45938456f1161c36b2341ff4519d1314b130302
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Tue Jul 10 16:46:24 2018 -0700

    Added more robust testing for the insert with aggregation and discovered a race condition that only seems to occur for values near MAX_INT. Still debugging.

commit a0532535f3dc692fe6dd6d22e207b9687339f196
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Tue Jul 10 08:18:27 2018 -0700

    Fixed bug in how the concurrent_unordered_map class was instantiated to use managed memory allocation. Need to allocate on heap using 'new' keyword. Implemented initial tests for insert + aggregation.

commit a6e21a750bcdfc433dc1a53ba02a16f16d575c1f
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Fri Jul 6 11:19:01 2018 -0700

    Added a device kernel to test device-side inserts into the hash map w/ aggregators. Need to resolve passing lambdas into a kernel call.

commit 7a244fb82616fdcd13137799550e63c316d7266f
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Fri Jul 6 11:18:29 2018 -0700

    Added user-defined overloads of atomicCAS for floats and doubles. Simplified the insertion + aggregator by using new atomicCAS overloads.

commit 19fa13bfdf775a5af01f888b3872ceeee5a05099
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Fri Jul 6 11:16:49 2018 -0700

    Updated the build_hash_tbl kernel to avoid using a non-integeral type as an index into an array.

commit ede73f83c5797fa8f5ddd1533fe08fc1b149c979
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Thu Jul 5 17:15:52 2018 -0700

    Completed an initial GPU implementation of insert with aggregation. Required to use messy branch logic to implement a generic atomic operation on any 32 or 64 bit types.

commit ca64ac0b2f98021ea54615f594d56bae62bacadf
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Thu Jul 5 15:14:28 2018 -0700

    Implemented an insert function for the concurrent_unordered_map class that accepts an aggregation function to perform on the value (host-side only currently). Added a single test to confirm its working.

commit 464b6e4265bafdab0d651a9d1d9a0af9a8d12b67

Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Thu Jul 5 11:28:47 2018 -0700

    Copied the concurrent_unordered_multimap class into a new concurrent_unordered_map class. This new class is where the insert w/ aggregation will be implemented.

commit 410f7575c71eef2bd2644c3c6de48c8cea15fa3e
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Thu Jul 5 10:45:04 2018 -0700

    Renamed hash-test.cu to multimap-test.cu. Added a test file for testing the Join API.

commit 9717c2d66e471f3739ed2d900ecdd7b5e4dc623d
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Thu Jul 5 10:44:19 2018 -0700

    Updated include paths to fix the build after reorganizing directory structure. Used relative paths, which should probably be replaced with CMake include directories.

commit 41073ab83681fb2a3801865da354f6275e85933e
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Thu Jul 5 10:18:26 2018 -0700

    Reorganized the directory structure of libgdf/src. Currently will not build as include paths have not been fixed.

commit 8a4aa81b5de8e659f7dcfcb8c42f595af242952e
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Tue Jul 3 17:07:38 2018 -0700

    Added additional tests for the concurrent_unordered_multimap for checking the maps initial state as well as host-side inserts.

commit d51f0b8641b2eef788e9dc42c561d1dc5ae699cb
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Tue Jul 3 16:52:11 2018 -0700

    Moved 'unused_element' from a non-type template parameter of concurrent_unordered_multimap to a member variable that is initialized on construction. This value is only used during the hash table initialization, and therefore moving it from a compile time to runtime constant should have no performance impact.

    Sorting hash-joined GDF for assertion

commit 3b52b1a36a2e057f4febe6b41be62a09e64a54cd
Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Thu Jun 21 09:15:18 2018 -0700

    Updated _merge_gdf to correctly return joined_indices. A deep copy of the join kernels results with cudautils.copy_array() for the left_indices and right_indices is required because currently apply_join frees the memory of its result. This seems inefficient. We'd like joined_indices to be able to reference the original apply_join result's device memory and have it freed when joined_indices goes out of scope.

Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Wed Jun 20 17:30:58 2018 -0700

    Created a new _merge_gdf function in dataframe.py for use as a multi-column join. Currently the call to apply_join fails in the test_joining because it expects the inputs to be a List of NumericalColumns, whereas a List of Series are being passed.

    Modified NumericalColumn.join() to be used only for single-column joins. Removed the 'left_on' and 'right_on' parameters. _hashjoin is still stubbed.

Author: Jake Hemstad <jhemstad@nvidia.com>
Date:   Wed Jun 20 11:17:59 2018 -0700

    Added a 'type' parameter to the NumericalColumn.join() function. Valid values are 'sort' or 'hash'. Moved the original join code to to the _sortjoin() function that is called when type=='sort'. Created an stubbed _hashjoin() function for when type='hash'. Changes should not break existing functionality, but pytest tests are currently failing for unknown reasons.
