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.
