❄️ Code freeze for branch-24.10 and v24.10 release

What does this mean?

Only critical/hotfix level issues should be merged into branch-24.10 until release (merging of this PR).

What is the purpose of this PR?

  • Update documentation
  • Allow testing for the new release
  • Enable a means to merge branch-24.10 into main for the release

Fix build failures with GCC 13 (#16488)
8068a2d 
Closes #16395

This PR resolves two types of compilation errors, allowing for successful builds with GCC 13:

- replacing the `cuco_allocator` strong type with an alias to fix a new build time check with GCC 13
- removing `std::move` when returning a temporary

Fix segmented-sort overlapped input/output indices (#16463)
e8156d4 
Fixes call to CUB `DeviceSegmentedSort::SortPairs` where the input and output indices pointed to the same temp memory. The documentation from https://nvidia.github.io/cccl/cub/api/structcub_1_1DeviceSegmentedSort.html#id8 indicates the `d_values_in` and `d_values_out` memory must not overlap so using the same pointer for both created invalid output in certain conditions. The internal function was implemented to expect the input values to be updated in-place. The fix uses separate device memory for the input and output indices.

Disallow cudf.Series to accept column in favor of ._from_column (#1…
6b0bff4 
…6454)

`cudf.Series` is a public constructor that happens to accept a private `ColumnBase` object. Many ops return Columns and is natural to want to reconstruct a `Series`.

This PR adds a `SingleColumnFrame._from_column` classmethod for instances where we need to wrap a new column in an `Index` or `Series`. This constructor also passes some unneeded validation in `ColumnAccessor` and `Series`

Contributes to rapidsai/build-planning#58.

`scikit-build-core==0.10.0` was released today (https://github.com/scikit-build/scikit-build-core/releases/tag/v0.10.0), and wheel-building configurations across RAPIDS are incompatible with it.

This proposes upgrading to that version and fixing configuration here in a way that:

* is compatible with that new `scikit-build-core` version
* takes advantage of the forward-compatibility mechanism (`minimum-version`) that `scikit-build-core` provides, to reduce the risk of needing to do this again in the future

Change IPv4 convert APIs to support UINT32 instead of INT64 (#16489)
cc75b05 
Changes the integer type for `cudf::strings::ipv4_to_integers` and `cudf::strings::integers_to_ipv4` to use UINT32 types instead of INT64. The INT64 type was originally chosen because libcudf did not support unsigned types at the time.
This is a breaking change since the basic input/output type is changed.

Fix date_range(start, end, freq) when end-start is divisible by freq (
4cd87d3 
#16516)

xref #16507

`date_range` generates its dates via `range`, and the end of this range was calculated via `math.ceil((end - start) / freq)`. If `(end - start) / freq` did not produce a remainder, `math.ceil` would not correctly increment this value by `1` to capture the last date.

Instead, this PR uses `math.floor((end - start) / freq) + 1` to always ensure the last date is captured

Pass batch size to JSON reader using environment variable (#16502)
cce00c0 
The JSON reader set the batch size to `INT_MAX` bytes since the motivation for implementing a batched JSON reader was to parse source files whose total size is larger than `INT_MAX` (#16138, #16162). However, we can use a much smaller batch size to evaluate the correctness of the reader and speed up tests significantly.
This PR focuses on reducing runtime of the batched reader test by setting the batch size to be used by the reader as an environment variable. 
The runtime of `JsonLargeReaderTest.MultiBatch` in `LARGE_STRINGS_TEST` gtest  drops from ~52s to ~3s.

Remove unneeded pair-iterator benchmark (#16511)
3a791cb 
Removes the pair-iterator benchmark logic. The remaining benchmarks use the null-replacement-iterator which uses the libcudf pair-iterator internally. There is no need for benchmarking this unique iterator pattern that is not used by libcudf.

The `cpp/benchmarks/iterator/iterator.cu` failed to compile with gcc 12 because the sum-reduce function cannot resolve adding `thrust::pair` objects together likely due to some recent changes in CCCL. Regardless, adding `thrust::pair` objects is not something we need to benchmark. The existing benchmark benchmarks libcudf's usage of the internal pair-iterator correctly.

Register read_parquet and read_csv with dask-expr (#16535)
5780c4d 
After dask/dask-expr#1114, Dask cuDF must register specific `read_parquet` and `read_csv` functions to be used when query-planning is enabled (the default).

**This PR is required for CI to pass with dask>2024.8.0**

**NOTE**: It probably doesn't make sense to add specific tests for this change. Once the 2014.7.1 dask pin is removed, all `dask_cudf` tests using `read_parquet` and  `read_csv` will fail without this change...

Ensure comparisons with pyints and integer series always succeed (#16532
cf3fabf 
)

When Python integers are compared to a series of integers, the result can always be correctly defined no matter the values of the Python integer.

This was always a very mild issue.  But with NumPy 2 behavior not upcasting the computation result type based on the value anymore, even things like:
```
cudf.Series([1, 2, 3], dtype="int8") < 1000
```
would fail.
(Similar paths could be taken for other integer scalars, but there would be mostly nice for performance.)

N.B. NumPy/pandas also support exact comparisons when mixing e.g. uint64 and int64.  This is another rare exception that cudf currently does not support.

This PR piggybacks on the existing CPU/Arrow Parquet infrastructure in dask-expr. With this PR,

```python
df = dask_cudf.read_parquet(path, filesystem="arrow")
```
will produce a `cudf`-backed collection using PyArrow for IO (i.e. disk->`pa.Table`->`cudf.DataFrame`). Before this PR, passing `filesystem="arrow"` will simply result in an error.

Although this code path is not ideal for fast/local storage, it can be **very** efficient for remote storage (e.g. S3).

[REVIEW] JSON host tree algorithms (#16545)
12ee360 
Depends on #16836
This change adds a new host tree building algorithms for JSON reader and utf8 field name support.

This constructs the device_column_tree using an adjacency list created from parent information.
This adjacency list is pruned based on input schema, and also types are enforced as per schema. `mark_is_pruned`
Tree is constructed from pruned adjacency list, (with mixed types handling). `construct_tree`

utf8 field name support added: (spark requested)
utf8 decoding of field names during hashing of field nodes so that utf8 encoded field names also match to same column.

All unit tests passes, 1 unit test added where old algorithm fails.
This code is kept under experimental flag.
