- gh-139700: Check consistency of the zip64 end of central
directory record. Support records with “zip64 extensible data”
if there are no bytes prepended to the ZIP file.
- gh-139400: xml.parsers.expat: Make sure that parent Expat
parsers are only garbage-collected once they are no longer
referenced by subparsers created by
ExternalEntityParserCreate(). Patch by Sebastian Pipping.
- gh-135661: Fix parsing start and end tags in
html.parser.HTMLParser according to the HTML5 standard.
* Whitespaces no longer accepted between </ and the tag name. E.g.
</ script> does not end the script section.
* Vertical tabulation (\v) and non-ASCII whitespaces no longer
recognized as whitespaces. The only whitespaces are \t\n\r\f and
space.
* Null character (U+0000) no longer ends the tag name.
* Attributes and slashes after the tag name in end tags are now
ignored, instead of terminating after the first > in quoted
attribute value. E.g. </script/foo=">"/>.
* Multiple slashes and whitespaces between the last attribute and
closing > are now ignored in both start and end tags. E.g. <a
foo=bar/ //>.
* Multiple = between attribute name and value are no longer
collapsed. E.g. <a foo==bar> produces attribute “foo” with value
“=bar”.
- gh-135661: Fix CDATA section parsing in html.parser.HTMLParser
according to the HTML5 standard: ] ]> and ]] > no longer end the
CDATA section. Add private method _set_support_cdata() which can
be used to specify how to parse <[CDATA[ — as a CDATA section in

Notes for packagers of Python3

==============================
|
|
|
|
0. Faster build turnaround
|
|
--------------------------
|
|
|
|
By default, python builds with profile-guided optimization. This needs
|
|
an additional run of the test suite and it is generally slow.
|
|
PGO build takes around 50 minutes.
|
|
|
|
For development, use "--without profileopt" option to disable PGO. This
|
|
shortens the build time to ~5 minutes including test suite.
|
|
|
|
1. import_failed.map
|
|
----------------------
|
|
|
|
This is a mechanism installed as part of python3-base, that places shim modules
|
|
on python's path (through a generated zzzz-import-failed-hooks.pth file, so that
|
|
it is imported as much at the end as makes sense; and an _import_failed subdir
|
|
of /usr/lib/pythonX.Y). Then when the user tries to import a module that is part
|
|
of a subpackage, the ImportError will contain a helpful message telling them
|
|
which missing subpackage to install.
|
|
|
|
This can sometimes cause problems on non-standard configurations, if the pth
|
|
gets included too early (for instance if you are using a script to include all
|
|
pths by hand in some strange order). Just something to look out for.
