Scheduled biweekly dependency update for week 26 #517

Closed pyup-bot closed 4 months ago

pyup-bot commented 4 months ago

Update argcomplete from 1.10.3 to 3.4.0.

Changelog ### 3.4.0 ``` =============================== - No stdin for python calls from bash completion functions (488) Prevents usage of stdin by (python) executables that are called during completion generation. This prevents the completion locking up the entire shell when the python script is broken i.e. it enters an interactive mode (REPL) instead of generating the completions, as expected. - Localize shell variable REPLY to avoid overwriting users’ value (489) The variable REPLY is used by default by the ``read`` shell builtin to store the return value, and like all bash/zsh variables, is scoped globally. This change allows this variable to be used for other needs by appropriately scoping its internal use by an argcomplete utility function that uses ``read``. ``` ### 3.3.0 ``` =============================== - Preserve compatibility with argparse option tuples of length 4. This update is required to use argcomplete on Python 3.11.9+ or 3.12.3+. ``` ### 3.2.3 ``` =============================== - Allow register-python-argcomplete output to be used as lazy-loaded zsh completion module (475) - Move debug_stream initialization to helper method to allow fd 9 behavior to be overridden in subclasses (471) ``` ### 3.2.2 ``` =============================== Expand tilde in zsh ``` ### 3.2.1 ``` =============================== - Allow explicit zsh global completion activation (467) ``` ### 3.2.0 ``` =============================== - Fix and test global completion in zsh (463, 466) - Add –yes option to activate-global-python-argcomplete (461) - Test suite improvements ``` ### 3.1.6 ``` =============================== - Respect user choice in activate-global-python-argcomplete ``` ### 3.1.5 ``` =============================== - Escape colon in zsh completions.

Update beautifulsoup4 from 4.8.2 to 4.12.3.

Changelog ### 4.11.1 ``` This release was done to ensure that the unit tests are packaged along with the released source. There are no functionality changes in this release, but there are a few other packaging changes: * The Japanese and Korean translations of the documentation are included. * The changelog is now packaged as CHANGELOG, and the license file is packaged as LICENSE. NEWS.txt and COPYING.txt are still present, but may be removed in the future. * TODO.txt is no longer packaged, since a TODO is not relevant for released code. ``` ### 4.11.0 ``` * Ported unit tests to use pytest. * Added special string classes, RubyParenthesisString and RubyTextString, to make it possible to treat ruby text specially in get_text() calls. [bug=1941980] * It's now possible to customize the way output is indented by providing a value for the 'indent' argument to the Formatter constructor. The 'indent' argument works very similarly to the argument of the same name in the Python standard library's json.dump() function. [bug=1955497] * If the charset-normalizer Python module (https://pypi.org/project/charset-normalizer/) is installed, Beautiful Soup will use it to detect the character sets of incoming documents. This is also the module used by newer versions of the Requests library. For the sake of backwards compatibility, chardet and cchardet both take precedence if installed. [bug=1955346] * Added a workaround for an lxml bug (https://bugs.launchpad.net/lxml/+bug/1948551) that causes problems when parsing a Unicode string beginning with BYTE ORDER MARK. [bug=1947768] * Issue a warning when an HTML parser is used to parse a document that looks like XML but not XHTML. [bug=1939121] * Do a better job of keeping track of namespaces as an XML document is parsed, so that CSS selectors that use namespaces will do the right thing more often. [bug=1946243] * Some time ago, the misleadingly named "text" argument to find-type methods was renamed to the more accurate "string." But this supposed "renaming" didn't make it into important places like the method signatures or the docstrings. That's corrected in this version. "text" still works, but will give a DeprecationWarning. [bug=1947038] * Fixed a crash when pickling a BeautifulSoup object that has no tree builder. [bug=1934003] * Fixed a crash when overriding multi_valued_attributes and using the html5lib parser. [bug=1948488] * Standardized the wording of the MarkupResemblesLocatorWarning warnings to omit untrusted input and make the warnings less judgmental about what you ought to be doing. [bug=1955450] * Removed support for the iconv_codec library, which doesn't seem to exist anymore and was never put up on PyPI. (The closest replacement on PyPI, iconv_codecs, is GPL-licensed, so we can't use it--it's also quite old.) ``` ### 4.10.0 ``` * This is the first release of Beautiful Soup to only support Python 3. I dropped Python 2 support to maintain support for newer versions (58 and up) of setuptools. See: https://github.com/pypa/setuptools/issues/2769 [bug=1942919] * The behavior of methods like .get_text() and .strings now differs depending on the type of tag. The change is visible with HTML tags like <script>, <style>, and <template>. Starting in 4.9.0, methods like get_text() returned no results on such tags, because the contents of those tags are not considered 'text' within the document as a whole. But a user who calls script.get_text() is working from a different definition of 'text' than a user who calls div.get_text()--otherwise there would be no need to call script.get_text() at all. In 4.10.0, the contents of (e.g.) a <script> tag are considered 'text' during a get_text() call on the tag itself, but not considered 'text' during a get_text() call on the tag's parent. Because of this change, calling get_text() on each child of a tag may now return a different result than calling get_text() on the tag itself. That's because different tags now have different understandings of what counts as 'text'. [bug=1906226] [bug=1868861] * NavigableString and its subclasses now implement the get_text() method, as well as the properties .strings and .stripped_strings. These methods will either return the string itself, or nothing, so the only reason to use this is when iterating over a list of mixed Tag and NavigableString objects. [bug=1904309] * The 'html5' formatter now treats attributes whose values are the empty string as HTML boolean attributes. Previously (and in other formatters), an attribute value must be set as None to be treated as a boolean attribute. In a future release, I plan to also give this behavior to the 'html' formatter. Patch by Isaac Muse. [bug=1915424] * The 'replace_with()' method now takes a variable number of arguments, and can be used to replace a single element with a sequence of elements. Patch by Bill Chandos. [rev=605] * Corrected output when the namespace prefix associated with a namespaced attribute is the empty string, as opposed to None. [bug=1915583] * Performance improvement when processing tags that speeds up overall tree construction by 2%. Patch by Morotti. [bug=1899358] * Corrected the use of special string container classes in cases when a single tag may contain strings with different containers; such as the <template> tag, which may contain both TemplateString objects and Comment objects. [bug=1913406] * The html.parser tree builder can now handle named entities found in the HTML5 spec in much the same way that the html5lib tree builder does. Note that the lxml HTML tree builder doesn't handle named entities this way. [bug=1924908] * Added a second way to pass specify encodings to UnicodeDammit and EncodingDetector, based on the order of precedence defined in the HTML5 spec, starting at: https://html.spec.whatwg.org/multipage/parsing.html#parsing-with-a-known-character-encoding Encodings in 'known_definite_encodings' are tried first, then byte-order-mark sniffing is run, then encodings in 'user_encodings' are tried. The old argument, 'override_encodings', is now a deprecated alias for 'known_definite_encodings'. This changes the default behavior of the html.parser and lxml tree builders, in a way that may slightly improve encoding detection but will probably have no effect. [bug=1889014] * Improve the warning issued when a directory name (as opposed to the name of a regular file) is passed as markup into the BeautifulSoup constructor. [bug=1913628] ``` ### 4.9.3 ``` * Implemented a significant performance optimization to the process of searching the parse tree. Patch by Morotti. [bug=1898212] ``` ### 4.9.2 ``` * Fixed a bug that caused too many tags to be popped from the tag stack during tree building, when encountering a closing tag that had no matching opening tag. [bug=1880420] * Fixed a bug that inconsistently moved elements over when passing a Tag, rather than a list, into Tag.extend(). [bug=1885710] * Specify the soupsieve dependency in a way that complies with PEP 508. Patch by Mike Nerone. [bug=1893696] * Change the signatures for BeautifulSoup.insert_before and insert_after (which are not implemented) to match PageElement.insert_before and insert_after, quieting warnings in some IDEs. [bug=1897120] ``` ### 4.9.1 ``` * Added a keyword argument 'on_duplicate_attribute' to the BeautifulSoupHTMLParser constructor (used by the html.parser tree builder) which lets you customize the handling of markup that contains the same attribute more than once, as in: <a href="url1" href="url2"> [bug=1878209] * Added a distinct subclass, GuessedAtParserWarning, for the warning issued when BeautifulSoup is instantiated without a parser being specified. [bug=1873787] * Added a distinct subclass, MarkupResemblesLocatorWarning, for the warning issued when BeautifulSoup is instantiated with 'markup' that actually seems to be a URL or the path to a file on disk. [bug=1873787] * The new NavigableString subclasses (Stylesheet, Script, and TemplateString) can now be imported directly from the bs4 package. * If you encode a document with a Python-specific encoding like 'unicode_escape', that encoding is no longer mentioned in the final XML or HTML document. Instead, encoding information is omitted or left blank. [bug=1874955] * Fixed test failures when run against soupselect 2.0. Patch by Tomáš Chvátal. [bug=1872279] ``` ### 4.9.0 ``` * Added PageElement.decomposed, a new property which lets you check whether you've already called decompose() on a Tag or NavigableString. * Embedded CSS and Javascript is now stored in distinct Stylesheet and Script tags, which are ignored by methods like get_text() since most people don't consider this sort of content to be 'text'. This feature is not supported by the html5lib treebuilder. [bug=1868861] * Added a Russian translation by 'authoress' to the repository. * Fixed an unhandled exception when formatting a Tag that had been decomposed.[bug=1857767] * Fixed a bug that happened when passing a Unicode filename containing non-ASCII characters as markup into Beautiful Soup, on a system that allows Unicode filenames. [bug=1866717] * Added a performance optimization to PageElement.extract(). Patch by Arthur Darcet. ``` ### 4.8.2 ``` * Added Python docstrings to all public methods of the most commonly used classes. * Added a Chinese translation by Deron Wang and a Brazilian Portuguese translation by Cezar Peixeiro to the repository. * Fixed two deprecation warnings. Patches by Colin Watson and Nicholas Neumann. [bug=1847592] [bug=1855301] * The html.parser tree builder now correctly handles DOCTYPEs that are not uppercase. [bug=1848401] * PageElement.select() now returns a ResultSet rather than a regular list, making it consistent with methods like find_all(). ``` ### 4.8.1 ``` * When the html.parser or html5lib parsers are in use, Beautiful Soup will, by default, record the position in the original document where each tag was encountered. This includes line number (Tag.sourceline) and position within a line (Tag.sourcepos). Based on code by Chris Mayo. [bug=1742921] * When instantiating a BeautifulSoup object, it's now possible to provide a dictionary ('element_classes') of the classes you'd like to be instantiated instead of Tag, NavigableString, etc. * Fixed the definition of the default XML namespace when using lxml 4.4. Patch by Isaac Muse. [bug=1840141] * Fixed a crash when pretty-printing tags that were not created during initial parsing. [bug=1838903] * Copying a Tag preserves information that was originally obtained from the TreeBuilder used to build the original Tag. [bug=1838903] * Raise an explanatory exception when the underlying parser completely rejects the incoming markup. [bug=1838877] * Avoid a crash when trying to detect the declared encoding of a Unicode document. [bug=1838877] * Avoid a crash when unpickling certain parse trees generated using html5lib on Python 3. [bug=1843545] ``` ### 4.8.0 ``` This release focuses on making it easier to customize Beautiful Soup's input mechanism (the TreeBuilder) and output mechanism (the Formatter). * You can customize the TreeBuilder object by passing keyword arguments into the BeautifulSoup constructor. Those keyword arguments will be passed along into the TreeBuilder constructor. The main reason to do this right now is to change how which attributes are treated as multi-valued attributes (the way 'class' is treated by default). You can do this with the 'multi_valued_attributes' argument. [bug=1832978] * The role of Formatter objects has been greatly expanded. The Formatter class now controls the following: - The function to call to perform entity substitution. (This was previously Formatter's only job.) - Which tags should be treated as containing CDATA and have their contents exempt from entity substitution. - The order in which a tag's attributes are output. [bug=1812422] - Whether or not to put a '/' inside a void element, e.g. '<br/>' vs '<br>' All preexisting code should work as before. * Added a new method to the API, Tag.smooth(), which consolidates multiple adjacent NavigableString elements. [bug=1697296] * &apos; (which is valid in XML, XHTML, and HTML 5, but not HTML 4) is always recognized as a named entity and converted to a single quote. [bug=1818721] ``` ### 4.7.1 ``` * Fixed a significant performance problem introduced in 4.7.0. [bug=1810617] * Fixed an incorrectly raised exception when inserting a tag before or after an identical tag. [bug=1810692] * Beautiful Soup will no longer try to keep track of namespaces that are not defined with a prefix; this can confuse soupselect. [bug=1810680] * Tried even harder to avoid the deprecation warning originally fixed in 4.6.1. [bug=1778909] ``` ### 4.7.0 ``` * Beautiful Soup's CSS Selector implementation has been replaced by a dependency on Isaac Muse's SoupSieve project (the soupsieve package on PyPI). The good news is that SoupSieve has a much more robust and complete implementation of CSS selectors, resolving a large number of longstanding issues. The bad news is that from this point onward, SoupSieve must be installed if you want to use the select() method. You don't have to change anything lf you installed Beautiful Soup through pip (SoupSieve will be automatically installed when you upgrade Beautiful Soup) or if you don't use CSS selectors from within Beautiful Soup. SoupSieve documentation: https://facelessuser.github.io/soupsieve/ * Added the PageElement.extend() method, which works like list.append(). [bug=1514970] * PageElement.insert_before() and insert_after() now take a variable number of arguments. [bug=1514970] * Fix a number of problems with the tree builder that caused trees that were superficially okay, but which fell apart when bits were extracted. Patch by Isaac Muse. [bug=1782928,1809910] * Fixed a problem with the tree builder in which elements that contained no content (such as empty comments and all-whitespace elements) were not being treated as part of the tree. Patch by Isaac Muse. [bug=1798699] * Fixed a problem with multi-valued attributes where the value contained whitespace. Thanks to Jens Svalgaard for the fix. [bug=1787453] * Clarified ambiguous license statements in the source code. Beautiful Soup is released under the MIT license, and has been since 4.4.0. * This file has been renamed from NEWS.txt to CHANGELOG. ``` ### 4.6.3 ``` * Exactly the same as 4.6.2. Re-released to make the README file render properly on PyPI. ``` ### 4.6.2 ``` * Fix an exception when a custom formatter was asked to format a void element. [bug=1784408] ``` ### 4.6.1 ``` * Stop data loss when encountering an empty numeric entity, and possibly in other cases. Thanks to tos.kamiya for the fix. [bug=1698503] * Preserve XML namespaces introduced inside an XML document, not just the ones introduced at the top level. [bug=1718787] * Added a new formatter, "html5", which represents void elements as "<element>" rather than "<element/>". [bug=1716272] * Fixed a problem where the html.parser tree builder interpreted a string like "&foo " as the character entity "&foo;" [bug=1728706] * Correctly handle invalid HTML numeric character entities like &147; which reference code points that are not Unicode code points. Note that this is only fixed when Beautiful Soup is used with the html.parser parser -- html5lib already worked and I couldn't fix it with lxml. [bug=1782933] * Improved the warning given when no parser is specified. [bug=1780571] * When markup contains duplicate elements, a select() call that includes multiple match clauses will match all relevant elements. [bug=1770596] * Fixed code that was causing deprecation warnings in recent Python 3 versions. Includes a patch from Ville Skyttä. [bug=1778909] [bug=1689496] * Fixed a Windows crash in diagnose() when checking whether a long markup string is a filename. [bug=1737121] * Stopped HTMLParser from raising an exception in very rare cases of bad markup. [bug=1708831] * Fixed a bug where find_all() was not working when asked to find a tag with a namespaced name in an XML document that was parsed as HTML. [bug=1723783] * You can get finer control over formatting by subclassing bs4.element.Formatter and passing a Formatter instance into (e.g.) encode(). [bug=1716272] * You can pass a dictionary of `attrs` into BeautifulSoup.new_tag. This makes it possible to create a tag with an attribute like 'name' that would otherwise be masked by another argument of new_tag. [bug=1779276] * Clarified the deprecation warning when accessing tag.fooTag, to cover the possibility that you might really have been looking for a tag called 'fooTag'. ``` ### 4.6.0 ``` * Added the `Tag.get_attribute_list` method, which acts like `Tag.get` for getting the value of an attribute, but which always returns a list, whether or not the attribute is a multi-value attribute. [bug=1678589] * It's now possible to use a tag's namespace prefix when searching, e.g. soup.find('namespace:tag') [bug=1655332] * Improved the handling of empty-element tags like <br> when using the html.parser parser. [bug=1676935] * HTML parsers treat all HTML4 and HTML5 empty element tags (aka void element tags) correctly. [bug=1656909] * Namespace prefix is preserved when an XML tag is copied. Thanks to Vikas for a patch and test. [bug=1685172] ``` ### 4.5.3 ``` * Fixed foster parenting when html5lib is the tree builder. Thanks to Geoffrey Sneddon for a patch and test. * Fixed yet another problem that caused the html5lib tree builder to create a disconnected parse tree. [bug=1629825] ``` ### 4.5.2 ``` * Apart from the version number, this release is identical to 4.5.3. Due to user error, it could not be completely uploaded to PyPI. Use 4.5.3 instead. ``` ### 4.5.1 ``` * Fixed a crash when passing Unicode markup that contained a processing instruction into the lxml HTML parser on Python 3. [bug=1608048] ``` ### 4.5.0 ``` * Beautiful Soup is no longer compatible with Python 2.6. This actually happened a few releases ago, but it's now official. * Beautiful Soup will now work with versions of html5lib greater than 0.99999999. [bug=1603299] * If a search against each individual value of a multi-valued attribute fails, the search will be run one final time against the complete attribute value considered as a single string. That is, if a tag has class="foo bar" and neither "foo" nor "bar" matches, but "foo bar" does, the tag is now considered a match. This happened in previous versions, but only when the value being searched for was a string. Now it also works when that value is a regular expression, a list of strings, etc. [bug=1476868] * Fixed a bug that deranged the tree when a whitespace element was reparented into a tag that contained an identical whitespace element. [bug=1505351] * Added support for CSS selector values that contain quoted spaces, such as tag[style="display: foo"]. [bug=1540588] * Corrected handling of XML processing instructions. [bug=1504393] * Corrected an encoding error that happened when a BeautifulSoup object was copied. [bug=1554439] * The contents of <textarea> tags will no longer be modified when the tree is prettified. [bug=1555829] * When a BeautifulSoup object is pickled but its tree builder cannot be pickled, its .builder attribute is set to None instead of being destroyed. This avoids a performance problem once the object is unpickled. [bug=1523629] * Specify the file and line number when warning about a BeautifulSoup object being instantiated without a parser being specified. [bug=1574647] * The `limit` argument to `select()` now works correctly, though it's not implemented very efficiently. [bug=1520530] * Fixed a Python 3 ByteWarning when a URL was passed in as though it were markup. Thanks to James Salter for a patch and test. [bug=1533762] * We don't run the check for a filename passed in as markup if the 'filename' contains a less-than character; the less-than character indicates it's most likely a very small document. [bug=1577864] ``` ### 4.4.1 ``` * Fixed a bug that deranged the tree when part of it was removed. Thanks to Eric Weiser for the patch and John Wiseman for a test. [bug=1481520] * Fixed a parse bug with the html5lib tree-builder. Thanks to Roel Kramer for the patch. [bug=1483781] * Improved the implementation of CSS selector grouping. Thanks to Orangain for the patch. [bug=1484543] * Fixed the test_detect_utf8 test so that it works when chardet is installed. [bug=1471359] * Corrected the output of Declaration objects. [bug=1477847] ``` ### 4.4.0 ``` Especially important changes: * Added a warning when you instantiate a BeautifulSoup object without explicitly naming a parser. [bug=1398866] * __repr__ now returns an ASCII bytestring in Python 2, and a Unicode string in Python 3, instead of a UTF8-encoded bytestring in both versions. In Python 3, __str__ now returns a Unicode string instead of a bytestring. [bug=1420131] * The `text` argument to the find_* methods is now called `string`, which is more accurate. `text` still works, but `string` is the argument described in the documentation. `text` may eventually change its meaning, but not for a very long time. [bug=1366856] * Changed the way soup objects work under copy.copy(). Copying a NavigableString or a Tag will give you a new NavigableString that's equal to the old one but not connected to the parse tree. Patch by Martijn Peters. [bug=1307490] * Started using a standard MIT license. [bug=1294662] * Added a Chinese translation of the documentation by Delong .w. New features: * Introduced the select_one() method, which uses a CSS selector but only returns the first match, instead of a list of matches. [bug=1349367] * You can now create a Tag object without specifying a TreeBuilder. Patch by Martijn Pieters. [bug=1307471] * You can now create a NavigableString or a subclass just by invoking the constructor. [bug=1294315] * Added an `exclude_encodings` argument to UnicodeDammit and to the Beautiful Soup constructor, which lets you prohibit the detection of an encoding that you know is wrong. [bug=1469408] * The select() method now supports selector grouping. Patch by Francisco Canas [bug=1191917] Bug fixes: * Fixed yet another problem that caused the html5lib tree builder to create a disconnected parse tree. [bug=1237763] * Force object_was_parsed() to keep the tree intact even when an element from later in the document is moved into place. [bug=1430633] * Fixed yet another bug that caused a disconnected tree when html5lib copied an element from one part of the tree to another. [bug=1270611] * Fixed a bug where Element.extract() could create an infinite loop in the remaining tree. * The select() method can now find tags whose names contain dashes. Patch by Francisco Canas. [bug=1276211] * The select() method can now find tags with attributes whose names contain dashes. Patch by Marek Kapolka. [bug=1304007] * Improved the lxml tree builder's handling of processing instructions. [bug=1294645] * Restored the helpful syntax error that happens when you try to import the Python 2 edition of Beautiful Soup under Python 3. [bug=1213387] * In Python 3.4 and above, set the new convert_charrefs argument to the html.parser constructor to avoid a warning and future failures. Patch by Stefano Revera. [bug=1375721] * The warning when you pass in a filename or URL as markup will now be displayed correctly even if the filename or URL is a Unicode string. [bug=1268888] * If the initial <html> tag contains a CDATA list attribute such as 'class', the html5lib tree builder will now turn its value into a list, as it would with any other tag. [bug=1296481] * Fixed an import error in Python 3.5 caused by the removal of the HTMLParseError class. [bug=1420063] * Improved docstring for encode_contents() and decode_contents(). [bug=1441543] * Fixed a crash in Unicode, Dammit's encoding detector when the name of the encoding itself contained invalid bytes. [bug=1360913] * Improved the exception raised when you call .unwrap() or .replace_with() on an element that's not attached to a tree. * Raise a NotImplementedError whenever an unsupported CSS pseudoclass is used in select(). Previously some cases did not result in a NotImplementedError. * It's now possible to pickle a BeautifulSoup object no matter which tree builder was used to create it. However, the only tree builder that survives the pickling process is the HTMLParserTreeBuilder ('html.parser'). If you unpickle a BeautifulSoup object created with some other tree builder, soup.builder will be None. [bug=1231545] ``` ### 4.3.2 ``` * Fixed a bug in which short Unicode input was improperly encoded to ASCII when checking whether or not it was the name of a file on disk. [bug=1227016] * Fixed a crash when a short input contains data not valid in filenames. [bug=1232604] * Fixed a bug that caused Unicode data put into UnicodeDammit to return None instead of the original data. [bug=1214983] * Combined two tests to stop a spurious test failure when tests are run by nosetests. [bug=1212445] ``` ### 4.3.1 ``` * Fixed yet another problem with the html5lib tree builder, caused by html5lib's tendency to rearrange the tree during parsing. [bug=1189267] * Fixed a bug that caused the optimized version of find_all() to return nothing. [bug=1212655] ``` ### 4.3.0 ``` * Instead of converting incoming data to Unicode and feeding it to the lxml tree builder in chunks, Beautiful Soup now makes successive guesses at the encoding of the incoming data, and tells lxml to parse the data as that encoding. Giving lxml more control over the parsing process improves performance and avoids a number of bugs and issues with the lxml parser which had previously required elaborate workarounds: - An issue in which lxml refuses to parse Unicode strings on some systems. [bug=1180527] - A returning bug that truncated documents longer than a (very small) size. [bug=963880] - A returning bug in which extra spaces were added to a document if the document defined a charset other than UTF-8. [bug=972466] This required a major overhaul of the tree builder architecture. If you wrote your own tree builder and didn't tell me, you'll need to modify your prepare_markup() method. * The UnicodeDammit code that makes guesses at encodings has been split into its own class, EncodingDetector. A lot of apparently redundant code has been removed from Unicode, Dammit, and some undocumented features have also been removed. * Beautiful Soup will issue a warning if instead of markup you pass it a URL or the name of a file on disk (a common beginner's mistake). * A number of optimizations improve the performance of the lxml tree builder by about 33%, the html.parser tree builder by about 20%, and the html5lib tree builder by about 15%. * All find_all calls should now return a ResultSet object. Patch by Aaron DeVore. [bug=1194034] ``` ### 4.2.1 ``` * The default XML formatter will now replace ampersands even if they appear to be part of entities. That is, "&lt;" will become "&amp;lt;". The old code was left over from Beautiful Soup 3, which didn't always turn entities into Unicode characters. If you really want the old behavior (maybe because you add new strings to the tree, those strings include entities, and you want the formatter to leave them alone on output), it can be found in EntitySubstitution.substitute_xml_containing_entities(). [bug=1182183] * Gave new_string() the ability to create subclasses of NavigableString. [bug=1181986] * Fixed another bug by which the html5lib tree builder could create a disconnected tree. [bug=1182089] * The .previous_element of a BeautifulSoup object is now always None, not the last element to be parsed. [bug=1182089] * Fixed test failures when lxml is not installed. [bug=1181589] * html5lib now supports Python 3. Fixed some Python 2-specific code in the html5lib test suite. [bug=1181624] * The html.parser treebuilder can now handle numeric attributes in text when the hexidecimal name of the attribute starts with a capital X. Patch by Tim Shirley. [bug=1186242] ``` ### 4.2.0 ``` * The Tag.select() method now supports a much wider variety of CSS selectors. - Added support for the adjacent sibling combinator (+) and the general sibling combinator (~). Tests by "liquider". [bug=1082144] - The combinators (>, +, and ~) can now combine with any supported selector, not just one that selects based on tag name. - Added limited support for the "nth-of-type" pseudo-class. Code by Sven Slootweg. [bug=1109952] * The BeautifulSoup class is now aliased to "_s" and "_soup", making it quicker to type the import statement in an interactive session: from bs4 import _s or from bs4 import _soup The alias may change in the future, so don't use this in code you're going to run more than once. * Added the 'diagnose' submodule, which includes several useful functions for reporting problems and doing tech support. - diagnose(data) tries the given markup on every installed parser, reporting exceptions and displaying successes. If a parser is not installed, diagnose() mentions this fact. - lxml_trace(data, html=True) runs the given markup through lxml's XML parser or HTML parser, and prints out the parser events as they happen. This helps you quickly determine whether a given problem occurs in lxml code or Beautiful Soup code. - htmlparser_trace(data) is the same thing, but for Python's built-in HTMLParser class. * In an HTML document, the contents of a <script> or <style> tag will no longer undergo entity substitution by default. XML documents work the same way they did before. [bug=1085953] * Methods like get_text() and properties like .strings now only give you strings that are visible in the document--no comments or processing commands. [bug=1050164] * The prettify() method now leaves the contents of <pre> tags alone. [bug=1095654] * Fix a bug in the html5lib treebuilder which sometimes created disconnected trees. [bug=1039527] * Fix a bug in the lxml treebuilder which crashed when a tag included an attribute from the predefined "xml:" namespace. [bug=1065617] * Fix a bug by which keyword arguments to find_parent() were not being passed on. [bug=1126734] * Stop a crash when unwisely messing with a tag that's been decomposed. [bug=1097699] * Now that lxml's segfault on invalid doctype has been fixed, fixed a corresponding problem on the Beautiful Soup end that was previously invisible. [bug=984936] * Fixed an exception when an overspecified CSS selector didn't match anything. Code by Stefaan Lippens. [bug=1168167] ``` ### 4.1.3 ``` * Skipped a test under Python 2.6 and Python 3.1 to avoid a spurious test failure caused by the lousy HTMLParser in those versions. [bug=1038503] * Raise a more specific error (FeatureNotFound) when a requested parser or parser feature is not installed. Raise NotImplementedError instead of ValueError when the user calls insert_before() or insert_after() on the BeautifulSoup object itself. Patch by Aaron Devore. [bug=1038301] ``` ### 4.1.2 ``` * As per PEP-8, allow searching by CSS class using the 'class_' keyword argument. [bug=1037624] * Display namespace prefixes for namespaced attribute names, instead of the fully-qualified names given by the lxml parser. [bug=1037597] * Fixed a crash on encoding when an attribute name contained non-ASCII characters. * When sniffing encodings, if the cchardet library is installed, Beautiful Soup uses it instead of chardet. cchardet is much faster. [bug=1020748] * Use logging.warning() instead of warning.warn() to notify the user that characters were replaced with REPLACEMENT CHARACTER. [bug=1013862] ``` ### 4.1.1 ``` * Fixed an html5lib tree builder crash which happened when html5lib moved a tag with a multivalued attribute from one part of the tree to another. [bug=1019603] * Correctly display closing tags with an XML namespace declared. Patch by Andreas Kostyrka. [bug=1019635] * Fixed a typo that made parsing significantly slower than it should have been, and also waited too long to close tags with XML namespaces. [bug=1020268] * get_text() now returns an empty Unicode string if there is no text, rather than an empty bytestring. [bug=1020387] ``` ### 4.1.0 ``` * Added experimental support for fixing Windows-1252 characters embedded in UTF-8 documents. (UnicodeDammit.detwingle()) * Fixed the handling of &quot; with the built-in parser. [bug=993871] * Comments, processing instructions, document type declarations, and markup declarations are now treated as preformatted strings, the way CData blocks are. [bug=1001025] * Fixed a bug with the lxml treebuilder that prevented the user from adding attributes to a tag that didn't originally have attributes. [bug=1002378] Thanks to Oliver Beattie for the patch. * Fixed some edge-case bugs having to do with inserting an element into a tag it's already inside, and replacing one of a tag's children with another. [bug=997529] * Added the ability to search for attribute values specified in UTF-8. [bug=1003974] This caused a major refactoring of the search code. All the tests pass, but it's possible that some searches will behave differently. ``` ### 4.0.5 ``` * Added a new method, wrap(), which wraps an element in a tag. * Renamed replace_with_children() to unwrap(), which is easier to understand and also the jQuery name of the function. * Made encoding substitution in <meta> tags completely transparent (no more %SOUP-ENCODING%). * Fixed a bug in decoding data that contained a byte-order mark, such as data encoded in UTF-16LE. [bug=988980] * Fixed a bug that made the HTMLParser treebuilder generate XML definitions ending with two question marks instead of one. [bug=984258] * Upon document generation, CData objects are no longer run through the formatter. [bug=988905] * The test suite now passes when lxml is not installed, whether or not html5lib is installed. [bug=987004] * Print a warning on HTMLParseErrors to let people know they should install a better parser library. ``` ### 4.0.4 ``` * Fixed a bug that sometimes created disconnected trees. * Fixed a bug with the string setter that moved a string around the tree instead of copying it. [bug=983050] * Attribute values are now run through the provided output formatter. Previously they were always run through the 'minimal' formatter. In the future I may make it possible to specify different formatters for attribute values and strings, but for now, consistent behavior is better than inconsistent behavior. [bug=980237] * Added the missing renderContents method from Beautiful Soup 3. Also added an encode_contents() method to go along with decode_contents(). * Give a more useful error when the user tries to run the Python 2 version of BS under Python 3. * UnicodeDammit can now convert Microsoft smart quotes to ASCII with UnicodeDammit(markup, smart_quotes_to="ascii"). ``` ### 4.0.3 ``` * Fixed a typo that caused some versions of Python 3 to convert the Beautiful Soup codebase incorrectly. * Got rid of the 4.0.2 workaround for HTML documents--it was unnecessary and the workaround was triggering a (possibly different, but related) bug in lxml. [bug=972466] ``` ### 4.0.2 ``` * Worked around a possible bug in lxml that prevents non-tiny XML documents from being parsed. [bug=963880, bug=963936] * Fixed a bug where specifying `text` while also searching for a tag only worked if `text` wanted an exact string match. [bug=955942] ``` ### 4.0.1 ``` * This is the first official release of Beautiful Soup 4. There is no ``` ### 4.0.0 ``` might treat "4.0.0" as being an earlier version than "4.0.0b10". * Brought BS up to date with the latest release of soupselect, adding CSS selector support for direct descendant matches and multiple CSS class matches. ``` ### 4.0.0b10 ``` * Added support for simple CSS selectors, taken from the soupselect project. * Fixed a crash when using html5lib. [bug=943246] * In HTML5-style <meta charset="foo"> tags, the value of the "charset" attribute is now replaced with the appropriate encoding on output. [bug=942714] * Fixed a bug that caused calling a tag to sometimes call find_all() with the wrong arguments. [bug=944426] * For backwards compatibility, brought back the BeautifulStoneSoup class as a deprecated wrapper around BeautifulSoup. ``` ### 4.0.0b9 ``` * Fixed the string representation of DOCTYPEs that have both a public ID and a system ID. * Fixed the generated XML declaration. * Renamed Tag.nsprefix to Tag.prefix, for consistency with NamespacedAttribute. * Fixed a test failure that occurred on Python 3.x when chardet was installed. * Made prettify() return Unicode by default, so it will look nice on Python 3 when passed into print(). ``` ### 4.0.0b8 ``` * All tree builders now preserve namespace information in the documents they parse. If you use the html5lib parser or lxml's XML parser, you can access the namespace URL for a tag as tag.namespace. However, there is no special support for namespace-oriented searching or tree manipulation. When you search the tree, you need to use namespace prefixes exactly as they're used in the original document. * The string representation of a DOCTYPE always ends in a newline. * Issue a warning if the user tries to use a SoupStrainer in conjunction with the html5lib tree builder, which doesn't support them. ``` ### 4.0.0b7 ``` * Upon decoding to string, any characters that can't be represented in your chosen encoding will be converted into numeric XML entity references. * Issue a warning if characters were replaced with REPLACEMENT CHARACTER during Unicode conversion. * Restored compatibility with Python 2.6. * The install process no longer installs docs or auxiliary text files. * It's now possible to deepcopy a BeautifulSoup object created with Python's built-in HTML parser. * About 100 unit tests that "test" the behavior of various parsers on invalid markup have been removed. Legitimate changes to those parsers caused these tests to fail, indicating that perhaps Beautiful Soup should not test the behavior of foreign libraries. The problematic unit tests have been reformulated as informational comparisons generated by the script scripts/demonstrate_parser_differences.py. This makes Beautiful Soup compatible with html5lib version 0.95 and future versions of HTMLParser. ``` ### 4.0.0b6 ``` * Multi-valued attributes like "class" always have a list of values, even if there's only one value in the list. * Added a number of multi-valued attributes defined in HTML5. * Stopped generating a space before the slash that closes an empty-element tag. This may come back if I add a special XHTML mode (http://www.w3.org/TR/xhtml1/#C_2), but right now it's pretty useless. * Passing text along with tag-specific arguments to a find* method: find("a", text="Click here") will find tags that contain the given text as their .string. Previously, the tag-specific arguments were ignored and only strings were searched. * Fixed a bug that caused the html5lib tree builder to build a partially disconnected tree. Generally cleaned up the html5lib tree builder. * If you restrict a multi-valued attribute like "class" to a string that contains spaces, Beautiful Soup will only consider it a match if the values correspond to that specific string. ``` ### 4.0.0b5 ``` * Rationalized Beautiful Soup's treatment of CSS class. A tag belonging to multiple CSS classes is treated as having a list of values for the 'class' attribute. Searching for a CSS class will match *any* of the CSS classes. This actually affects all attributes that the HTML standard defines as taking multiple values (class, rel, rev, archive, accept-charset, and headers), but 'class' is by far the most common. [bug=41034] * If you pass anything other than a dictionary as the second argument to one of the find* methods, it'll assume you want to use that object to search against a tag's CSS classes. Previously this only worked if you passed in a string. * Fixed a bug that caused a crash when you passed a dictionary as an attribute value (possibly because you mistyped "attrs"). [bug=842419] * Unicode, Dammit now detects the encoding in HTML 5-style <meta> tags like <meta charset="utf-8" />. [bug=837268] * If Unicode, Dammit can't figure out a consistent encoding for a page, it will try each of its guesses again, with errors="replace" instead of errors="strict". This may mean that some data gets replaced with REPLACEMENT CHARACTER, but at least most of it will get turned into Unicode. [bug=754903] * Patched over a bug in html5lib (?) that was crashing Beautiful Soup on certain kinds of markup. [bug=838800] * Fixed a bug that wrecked the tree if you replaced an element with an empty string. [bug=728697] * Improved Unicode, Dammit's behavior when you give it Unicode to begin with. ``` ### 4.0.0b4 ``` * Added BeautifulSoup.new_string() to go along with BeautifulSoup.new_tag() * BeautifulSoup.new_tag() will follow the rules of whatever tree-builder was used to create the original BeautifulSoup object. A new <p> tag will look like "<p />" if the soup object was created to parse XML, but it will look like "<p></p>" if the soup object was created to parse HTML. * We pass in strict=False to html.parser on Python 3, greatly improving html.parser's ability to handle bad HTML. * We also monkeypatch a serious bug in html.parser that made strict=False disastrous on Python 3.2.2. * Replaced the "substitute_html_entities" argument with the more general "formatter" argument. * Bare ampersands and angle brackets are always converted to XML entities unless the user prevents it. * Added PageElement.insert_before() and PageElement.insert_after(), which let you put an element into the parse tree with respect to some other element. * Raise an exception when the user tries to do something nonsensical like insert a tag into itself. ``` ### 4.0.0b3 ``` Beautiful Soup 4 is a nearly-complete rewrite that removes Beautiful Soup's custom HTML parser in favor of a system that lets you write a little glue code and plug in any HTML or XML parser you want. Beautiful Soup 4.0 comes with glue code for four parsers: * Python's standard HTMLParser (html.parser in Python 3) * lxml's HTML and XML parsers * html5lib's HTML parser HTMLParser is the default, but I recommend you install lxml if you can. For complete documentation, see the Sphinx documentation in bs4/doc/source/. What follows is a summary of the changes from Beautiful Soup 3. === The module name has changed === Previously you imported the BeautifulSoup class from a module also called BeautifulSoup. To save keystrokes and make it clear which version of the API is in use, the module is now called 'bs4': >>> from bs4 import BeautifulSoup === It works with Python 3 === Beautiful Soup 3.1.0 worked with Python 3, but the parser it used was so bad that it barely worked at all. Beautiful Soup 4 works with Python 3, and since its parser is pluggable, you don't sacrifice quality. Special thanks to Thomas Kluyver and Ezio Melotti for getting Python 3 support to the finish line. Ezio Melotti is also to thank for greatly improving the HTML parser that comes with Python 3.2. === CDATA sections are normal text, if they're understood at all. === Currently, the lxml and html5lib HTML parsers ignore CDATA sections in markup: <p><![CDATA[foo]]></p> => <p></p> A future version of html5lib will turn CDATA sections into text nodes, but only within tags like <svg> and <math>: <svg><![CDATA[foo]]></svg> => <p>foo</p> The default XML parser (which uses lxml behind the scenes) turns CDATA sections into ordinary text elements: <p><![CDATA[foo]]></p> => <p>foo</p> In theory it's possible to preserve the CDATA sections when using the XML parser, but I don't see how to get it to work in practice. === Miscellaneous other stuff === If the BeautifulSoup instance has .is_xml set to True, an appropriate XML declaration will be emitted when the tree is transformed into a string: <?xml version="1.0" encoding="utf-8"> <markup> ... </markup> The ['lxml', 'xml'] tree builder sets .is_xml to True; the other tree builders set it to False. If you want to parse XHTML with an HTML parser, you can set it manually. ``` ### 3.2 ``` to make it obvious which one you should use. ``` ### 3.1.0 ``` A hybrid version that supports 2.4 and can be automatically converted to run under Python 3.0. There are three backwards-incompatible changes you should be aware of, but no new features or deliberate behavior changes. 1. str() may no longer do what you want. This is because the meaning of str() inverts between Python 2 and 3; in Python 2 it gives you a byte string, in Python 3 it gives you a Unicode string. The effect of this is that you can't pass an encoding to .__str__ anymore. Use encode() to get a string and decode() to get Unicode, and you'll be ready (well, readier) for Python 3. 2. Beautiful Soup is now based on HTMLParser rather than SGMLParser, which is gone in Python 3. There's some bad HTML that SGMLParser handled but HTMLParser doesn't, usually to do with attribute values that aren't closed or have brackets inside them: <a href="foo</a>, </a><a href="bar">baz</a> <a b="<a>">', '<a b="&lt;a&gt;"></a><a>"></a> A later version of Beautiful Soup will allow you to plug in different parsers to make tradeoffs
