Fix readline history truncation when length is reduced The `readline.set_history_length()` function did not previously truncate the in-memory history when the new length was set to a value smaller than the current number of history items. This could lead to unexpected behavior where `get_history_length()` would still report the old length and writing the history to a file would write more entries than the new limit. This patch modifies `set_history_length()` to explicitly remove the oldest history entries using `remove_history()` when the length is decreased, ensuring the in-memory history is correctly truncated to the new limit. This brings the function's behavior in line with expectations and fixes failures in `test_write_read_limited_history`.
Python 3 in SUSE
==============
* Subpackages *
Python 3 is split into several subpackages, based on external dependencies.
The main package 'python3' has soft dependencies on all subpackages needed to
assemble the standard library; however, these might not all be installed by default.
If you attempt to import a module that is currently not installed, an ImportError is thrown,
with instructions to install the missing subpackage. Installing the subpackage might result
in installing libraries that the subpackage requires to function.
* ensurepip *
The 'ensurepip' module from Python 3 standard library (PEP 453) is supposed to deploy
a bundled copy of the pip installer. This makes no sense in a managed distribution like SUSE.
Instead, you need to install package 'python3-pip'. Usually this will be installed automatically
with 'python3'.
Using 'ensurepip' when pip is not installed will result in an ImportError with instructions
to install 'python3-pip'.
* Documentation *
You can find documentation in seprarate packages: python3-doc and
python3-doc-pdf. These contan following documents:
Tutorial, What's New in Python, Global Module Index, Library Reference,
Macintosh Module Reference, Installing Python Modules, Distributing Python
Modules, Language Reference, Extending and Embedding, Python/C API,
Documenting Python
The python3-doc package constains many text files from source tarball.
* Interactive mode *
Interactive mode is by default enhanced with of history and command completion.
If you don't like these features, you can unset the PYTHONSTARTUP variable
in your .profile or disable it system wide in /etc/profile.d/python.sh.
