From ed7380fe51bd589ab8e23a2bf8556a4182f7c553 Mon Sep 17 00:00:00 2001 From: Tom Augspurger Date: Thu, 21 Jun 2018 06:09:15 -0500 Subject: [PATCH 01/43] DOC: Change release and whatsnew Changes: * We will include the correct (latest on master or maintenance branch) whatsnew directly in the index.rst toctree * Contributors are included in the whatsnew for each version (automatically) * Removed release.rst * Added new releases.rst which has toctrees for each release Incidental changes * Updated style.ipynb. Writing the jinja template was confusing sphinx. We included it in the git source now. * Fixing some inconsitent header levels (will do more) * Refactored announce.py to support auto-generated contributors --- .gitignore | 1 - doc/source/conf.py | 56 ++++++++- doc/source/index.rst.template | 4 +- doc/source/release_index.rst | 34 ++++++ doc/source/releases.rst | 193 ++++++++++++++++++++++++++++++++ doc/source/style.ipynb | 138 +++++++++++++++-------- doc/source/templates/myhtml.tpl | 5 + doc/source/whatsnew.rst | 103 ----------------- doc/source/whatsnew/v0.23.0.txt | 14 ++- doc/source/whatsnew/v0.23.1.txt | 11 +- doc/source/whatsnew/v0.23.2.txt | 11 +- doc/source/whatsnew/v0.24.0.txt | 71 +++++++----- scripts/announce.py | 33 +++--- 13 files changed, 468 insertions(+), 206 deletions(-) create mode 100644 doc/source/release_index.rst create mode 100644 doc/source/releases.rst create mode 100644 doc/source/templates/myhtml.tpl diff --git a/.gitignore b/.gitignore index 96b1f945870de..97f5204bcfe81 100644 --- a/.gitignore +++ b/.gitignore @@ -107,6 +107,5 @@ doc/build/html/index.html # Windows specific leftover: doc/tmp.sv doc/source/styled.xlsx -doc/source/templates/ env/ doc/source/savefig/ diff --git a/doc/source/conf.py b/doc/source/conf.py index 29f947e1144ea..04e1775833685 100644 --- a/doc/source/conf.py +++ b/doc/source/conf.py @@ -40,6 +40,7 @@ # documentation root, use os.path.abspath to make it absolute, like shown here. # sys.path.append(os.path.abspath('.')) sys.path.insert(0, os.path.abspath('../sphinxext')) +sys.path.insert(0, os.path.abspath('../../scripts')) sys.path.extend([ @@ -53,6 +54,7 @@ # numpydoc is available in the sphinxext directory, and can't be imported # until sphinxext is available in the Python path from numpydoc.docscrape import NumpyDocString +import announce # -- General configuration ----------------------------------------------- @@ -120,7 +122,10 @@ templates_path = ['../_templates'] # The suffix of source filenames. -source_suffix = '.rst' +source_suffix = [ + '.rst', + '.txt', +] # The encoding of source files. source_encoding = 'utf-8' @@ -298,8 +303,39 @@ for page in moved_api_pages } + +common_imports = """\ +.. currentmodule:: pandas + +.. ipython:: python + :suppress: + + import numpy as np + from pandas import * + import pandas as pd + randn = np.random.randn + np.set_printoptions(precision=4, suppress=True) + options.display.max_rows = 15 +""" + + +def get_contributors(start, end): + + return announce.build_string('{}..{}'.format(start, end), None) + + +contributors = { + 'v0.24.0': announce.build_string('v0.23.1..HEAD'), + 'v0.23.2': announce.build_string('v0.23.1..HEAD'), + 'v0.23.1': announce.build_string('v0.23.0..v0.23.1'), + 'v0.23.0': announce.build_string('v0.22.0..v0.23.0'), +} + + html_context = { - 'redirects': {old: new for old, new in moved_api_pages} + 'redirects': {old: new for old, new in moved_api_pages}, + 'common_imports': common_imports, + 'contributors': contributors, } # If false, no module index is generated. @@ -649,7 +685,23 @@ def process_class_docstrings(app, what, name, obj, options, lines): ] +def rstjinja(app, docname, source): + """ + Render our pages as a jinja template for fancy templating goodness. + """ + # http://ericholscher.com/blog/2016/jul/25/integrating-jinja-rst-sphinx/ + # Make sure we're outputting HTML + if app.builder.format != 'html': + return + src = source[0] + rendered = app.builder.templates.render_string( + src, app.config.html_context + ) + source[0] = rendered + + def setup(app): + app.connect("source-read", rstjinja) app.connect("autodoc-process-docstring", remove_flags_docstring) app.connect("autodoc-process-docstring", process_class_docstrings) app.add_autodocumenter(AccessorDocumenter) diff --git a/doc/source/index.rst.template b/doc/source/index.rst.template index f5ac7b77f4db1..5339aec6d0ed3 100644 --- a/doc/source/index.rst.template +++ b/doc/source/index.rst.template @@ -118,7 +118,7 @@ See the package overview for more detail about what's in the library. {{ single_doc }} {% endif -%} {% if not single_doc -%} - whatsnew + What's New install contributing overview @@ -159,5 +159,5 @@ See the package overview for more detail about what's in the library. developer internals extending - release + releases {% endif -%} diff --git a/doc/source/release_index.rst b/doc/source/release_index.rst new file mode 100644 index 0000000000000..53e584ec6abea --- /dev/null +++ b/doc/source/release_index.rst @@ -0,0 +1,34 @@ +.. _release: + +.. currentmodule:: pandas + +.. ipython:: python + :suppress: + + import pandas as pd + import numpy as np + np.random.seed(123456) + np.set_printoptions(precision=4, suppress=True) + import matplotlib.pyplot as plt + plt.close('all') + + pd.options.display.max_rows=15 + import pandas.util.testing as tm + +************* +Release Notes +************* + +This is the list of changes to pandas between each release.

Things like: - - - series.ix[[d1, d2, d3]] - - frame.ix[5:10, ['C', 'B', 'A']], frame.ix[5:10, 'A':'C'] - - frame.ix[date1:date2] - -- Significantly enhanced `groupby` functionality - - - Can groupby multiple keys, e.g. df.groupby(['key1', 'key2']). Iteration with - multiple groupings products a flattened tuple - - "Nuisance" columns (non-aggregatable) will automatically be excluded from - DataFrame aggregation operations - - Added automatic "dispatching to Series / DataFrame methods to more easily - invoke methods on groups. e.g. s.groupby(crit).std() will work even though - `std` is not implemented on the `GroupBy` class - -- Hierarchical / multi-level indexing - - - New the `MultiIndex` class. Integrated `MultiIndex` into `Series` and - `DataFrame` fancy indexing, slicing, __getitem__ and __setitem, - reindexing, etc. Added `level` keyword argument to `groupby` to enable - grouping by a level of a `MultiIndex` - -- New data reshaping functions: `stack` and `unstack` on DataFrame and Series - - - Integrate with MultiIndex to enable sophisticated reshaping of data - -- `Index` objects (labels for axes) are now capable of holding tuples -- `Series.describe`, `DataFrame.describe`: produces an R-like table of summary - statistics about each data column -- `DataFrame.quantile`, `Series.quantile` for computing sample quantiles of data - across requested axis -- Added general `DataFrame.dropna` method to replace `dropIncompleteRows` and - `dropEmptyRows`, deprecated those. -- `Series` arithmetic methods with optional fill_value for missing data, - e.g. a.add(b, fill_value=0). If a location is missing for both it will still - be missing in the result though. -- fill_value option has been added to `DataFrame`.{add, mul, sub, div} methods - similar to `Series` -- Boolean indexing with `DataFrame` objects: data[data > 0.1] = 0.1 or - data[data> other] = 1. -- `pytz` / tzinfo support in `DateRange` - - - `tz_localize`, `tz_normalize`, and `tz_validate` methods added - -- Added `ExcelFile` class to `pandas.io.parsers` for parsing multiple sheets out - of a single Excel 2003 document -- `GroupBy` aggregations can now optionally *broadcast*, e.g. produce an object - of the same size with the aggregated value propagated -- Added `select` function in all data structures: reindex axis based on - arbitrary criterion (function returning boolean value), - e.g. frame.select(lambda x: 'foo' in x, axis=1) -- `DataFrame.consolidate` method, API function relating to redesigned internals -- `DataFrame.insert` method for inserting column at a specified location rather - than the default __setitem__ behavior (which puts it at the end) -- `HDFStore` class in `pandas.io.pytables` has been largely rewritten using - patches from Jeff Reback from others. It now supports mixed-type `DataFrame` - and `Series` data and can store `Panel` objects. It also has the option to - query `DataFrame` and `Panel` data. Loading data from legacy `HDFStore` - files is supported explicitly in the code -- Added `set_printoptions` method to modify appearance of DataFrame tabular - output -- `rolling_quantile` functions; a moving version of `Series.quantile` / - `DataFrame.quantile` -- Generic `rolling_apply` moving window function -- New `drop` method added to `Series`, `DataFrame`, etc. which can drop a set of - labels from an axis, producing a new object -- `reindex` methods now sport a `copy` option so that data is not forced to be - copied then the resulting object is indexed the same -- Added `sort_index` methods to Series and Panel. Renamed `DataFrame.sort` - to `sort_index`. Leaving `DataFrame.sort` for now. -- Added ``skipna`` option to statistical instance methods on all the data - structures -- `pandas.io.data` module providing a consistent interface for reading time - series data from several different sources - -Improvements to existing features -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -- The 2-dimensional `DataFrame` and `DataMatrix` classes have been extensively - redesigned internally into a single class `DataFrame`, preserving where - possible their optimal performance characteristics. This should reduce - confusion from users about which class to use. - - - Note that under the hood there is a new essentially "lazy evaluation" - scheme within respect to adding columns to DataFrame. During some - operations, like-typed blocks will be "consolidated" but not before. - -- `DataFrame` accessing columns repeatedly is now significantly faster than - `DataMatrix` used to be in 0.3.0 due to an internal Series caching mechanism - (which are all views on the underlying data) -- Column ordering for mixed type data is now completely consistent in - `DataFrame`. In prior releases, there was inconsistent column ordering in - `DataMatrix` -- Improved console / string formatting of DataMatrix with negative numbers -- Improved tabular data parsing functions, `read_table` and `read_csv`: - - - Added `skiprows` and `na_values` arguments to `pandas.io.parsers` functions - for more flexible IO - - `parseCSV` / `read_csv` functions and others in `pandas.io.parsers` now can - take a list of custom NA values, and also a list of rows to skip - -- Can slice `DataFrame` and get a view of the data (when homogeneously typed), - e.g. frame.xs(idx, copy=False) or frame.ix[idx] -- Many speed optimizations throughout `Series` and `DataFrame` -- Eager evaluation of groups when calling ``groupby`` functions, so if there is - an exception with the grouping function it will raised immediately versus - sometime later on when the groups are needed -- `datetools.WeekOfMonth` offset can be parameterized with `n` different than 1 - or -1. -- Statistical methods on DataFrame like `mean`, `std`, `var`, `skew` will now - ignore non-numerical data. Before a not very useful error message was - generated. A flag `numeric_only` has been added to `DataFrame.sum` and - `DataFrame.count` to enable this behavior in those methods if so desired - (disabled by default) -- `DataFrame.pivot` generalized to enable pivoting multiple columns into a - `DataFrame` with hierarchical columns -- `DataFrame` constructor can accept structured / record arrays -- `Panel` constructor can accept a dict of DataFrame-like objects. Do not - need to use `from_dict` anymore (`from_dict` is there to stay, though). - -API Changes -~~~~~~~~~~~ - -- The `DataMatrix` variable now refers to `DataFrame`, will be removed within - two releases -- `WidePanel` is now known as `Panel`. The `WidePanel` variable in the pandas - namespace now refers to the renamed `Panel` class -- `LongPanel` and `Panel` / `WidePanel` now no longer have a common - subclass. `LongPanel` is now a subclass of `DataFrame` having a number of - additional methods and a hierarchical index instead of the old - `LongPanelIndex` object, which has been removed. Legacy `LongPanel` pickles - may not load properly -- Cython is now required to build `pandas` from a development branch. This was - done to avoid continuing to check in cythonized C files into source - control. Builds from released source distributions will not require Cython -- Cython code has been moved up to a top level `pandas/src` directory. Cython - extension modules have been renamed and promoted from the `lib` subpackage to - the top level, i.e. - - - `pandas.lib.tseries` -> `pandas._tseries` - - `pandas.lib.sparse` -> `pandas._sparse` - -- `DataFrame` pickling format has changed. Backwards compatibility for legacy - pickles is provided, but it's recommended to consider PyTables-based - `HDFStore` for storing data with a longer expected shelf life -- A `copy` argument has been added to the `DataFrame` constructor to avoid - unnecessary copying of data. Data is no longer copied by default when passed - into the constructor -- Handling of boolean dtype in `DataFrame` has been improved to support storage - of boolean data with NA / NaN values. Before it was being converted to float64 - so this should not (in theory) cause API breakage -- To optimize performance, Index objects now only check that their labels are - unique when uniqueness matters (i.e. when someone goes to perform a - lookup). This is a potentially dangerous tradeoff, but will lead to much - better performance in many places (like groupby). -- Boolean indexing using Series must now have the same indices (labels) -- Backwards compatibility support for begin/end/nPeriods keyword arguments in - DateRange class has been removed -- More intuitive / shorter filling aliases `ffill` (for `pad`) and `bfill` (for - `backfill`) have been added to the functions that use them: `reindex`, - `asfreq`, `fillna`. -- `pandas.core.mixins` code moved to `pandas.core.generic` -- `buffer` keyword arguments (e.g. `DataFrame.toString`) renamed to `buf` to - avoid using Python built-in name -- `DataFrame.rows()` removed (use `DataFrame.index`) -- Added deprecation warning to `DataFrame.cols()`, to be removed in next release -- `DataFrame` deprecations and de-camelCasing: `merge`, `asMatrix`, - `toDataMatrix`, `_firstTimeWithValue`, `_lastTimeWithValue`, `toRecords`, - `fromRecords`, `tgroupby`, `toString` -- `pandas.io.parsers` method deprecations - - - `parseCSV` is now `read_csv` and keyword arguments have been de-camelCased - - `parseText` is now `read_table` - - `parseExcel` is replaced by the `ExcelFile` class and its `parse` method - -- `fillMethod` arguments (deprecated in prior release) removed, should be - replaced with `method` -- `Series.fill`, `DataFrame.fill`, and `Panel.fill` removed, use `fillna` - instead -- `groupby` functions now exclude NA / NaN values from the list of groups. This - matches R behavior with NAs in factors e.g. with the `tapply` function -- Removed `parseText`, `parseCSV` and `parseExcel` from pandas namespace -- `Series.combineFunc` renamed to `Series.combine` and made a bit more general - with a `fill_value` keyword argument defaulting to NaN -- Removed `pandas.core.pytools` module. Code has been moved to - `pandas.core.common` -- Tacked on `groupName` attribute for groups in GroupBy renamed to `name` -- Panel/LongPanel `dims` attribute renamed to `shape` to be more conforming -- Slicing a `Series` returns a view now -- More Series deprecations / renaming: `toCSV` to `to_csv`, `asOf` to `asof`, - `merge` to `map`, `applymap` to `apply`, `toDict` to `to_dict`, - `combineFirst` to `combine_first`. Will print `FutureWarning`. -- `DataFrame.to_csv` does not write an "index" column label by default - anymore since the output file can be read back without it. However, there - is a new ``index_label`` argument. So you can do ``index_label='index'`` to - emulate the old behavior -- `datetools.Week` argument renamed from `dayOfWeek` to `weekday` -- `timeRule` argument in `shift` has been deprecated in favor of using the - `offset` argument for everything. So you can still pass a time rule string - to `offset` -- Added optional `encoding` argument to `read_csv`, `read_table`, `to_csv`, - `from_csv` to handle unicode in Python 2.x - -Bug Fixes -~~~~~~~~~ - -- Column ordering in `pandas.io.parsers.parseCSV` will match CSV in the presence - of mixed-type data -- Fixed handling of Excel 2003 dates in `pandas.io.parsers` -- `DateRange` caching was happening with high resolution `DateOffset` objects, - e.g. `DateOffset(seconds=1)`. This has been fixed -- Fixed __truediv__ issue in `DataFrame` -- Fixed `DataFrame.toCSV` bug preventing IO round trips in some cases -- Fixed bug in `Series.plot` causing matplotlib to barf in exceptional cases -- Disabled `Index` objects from being hashable, like ndarrays -- Added `__ne__` implementation to `Index` so that operations like ts[ts != idx] - will work -- Added `__ne__` implementation to `DataFrame` -- Bug / unintuitive result when calling `fillna` on unordered labels -- Bug calling `sum` on boolean DataFrame -- Bug fix when creating a DataFrame from a dict with scalar values -- Series.{sum, mean, std, ...} now return NA/NaN when the whole Series is NA -- NumPy 1.4 through 1.6 compatibility fixes -- Fixed bug in bias correction in `rolling_cov`, was affecting `rolling_corr` -
