- Tools/Demos
- gh-135968: Stubs for strip are now provided as part of an
iOS install.
- gh-133600: Backport file reorganization for .
Tools/wasm/wasi This should make backporting future code .
changes easier. It also simplifies instructions around how.
to do WASI builds in the devguide .
- Tests
- gh-135966: The iOS testbed now handles the app_packages
folder as a site directory.
- gh-135494: Fix regrtest to support excluding tests from
--pgo tests. Patch by Victor Stinner.
- Security
- gh-136053: marshal: fix a possible crash when deserializing
slice objects.
- 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/ //>.

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.
