<title>Python and Python 3 Changes</title>
|

|

<para>
|

The following are auto-packaging changes to Python and Python 3:
|
||||
</para>
|
||||
<para>
|
||||
The script-managed <filename>python-*-manifest.inc</filename> files
|
||||
that were previously used to generate Python and Python 3
|
||||
packages have been replaced with a JSON-based file that is
|
||||
easier to read and maintain.
|
||||
A new task is available for maintainers of the Python recipes to
|
||||
update the JSON file when upgrading to new Python versions.
|
||||
You can now edit the file directly instead of having to edit a
|
||||
script and run it to update the file.
|
||||
</para>
|
||||
<para>
|
||||
One particular change to note is that the Python recipes no longer
|
||||
have build-time provides for their packages.
|
||||
This assumes <filename>python-foo</filename> is one of the packages
|
||||
provided by the Python recipe.
|
||||
You can no longer run <filename>bitbake python-foo</filename> or
|
||||
have a <ulink url='&YOCTO_DOCS_REF_URL;#var-DEPENDS'><filename>DEPENDS</filename></ulink> on
|
||||
<filename>python-foo</filename>, but doing either of the following
|
||||
causes the package to work as expected:
|
||||
<literallayout class='monospaced'>
|
||||
IMAGE_INSTALL_append = " python-foo"
|
||||
</literallayout>
|
||||
or
|
||||
<literallayout class='monospaced'>
|
||||
RDEPENDS_${PN} = "python-foo"
|
||||
</literallayout>
|
||||
The earlier build-time provides behavior was a quirk of the way the
|
||||
Python manifest file was created.
