Revert "Performance improvement of 'python-shell-get-process'"

2026-02-07T12:41:10+00:00

This reverts commit 83b4f1ba26844c178e57ecb93ea8db36e8e6fa89.
We concluded that it is better to use 'project-name-cached'.

Fix down-list navigation in python-ts-mode

2026-01-21T18:02:56+00:00

* lisp/progmodes/python.el (python-ts-mode):
Set 'treesit-sexp-thing-down-list' to 'list' to override
sexp navigation with list navigation (bug#72478).

* lisp/emacs-lisp/lisp.el (up-list): Mention 'up-list-function' in docstring.

Performance improvement of 'python-shell-get-process'

2026-01-17T16:09:03+00:00

'python-shell-get-process' is frequently called from
'python-eldoc--get-doc-at-point' and etc., invoking
'project-current' unless there is a buffer-specific Inferior
Python process.  When the buffer is a remote buffer not
belonging to any project and has significant latency,
'project-current' may take a long time.  To avoid this,
implement a process cache in 'python-shell-get-process'.

* lisp/progmodes/python.el (python-shell--process-cache)
(python-shell--process-cache-valid): New variables.
(python-shell--invalidate-process-cache): New function.
(python-shell-make-comint): Add a call to the above function.
(python-shell-get-process): Add process cache.  (Bug#80045)

Improve non-native completion in Python mode

2026-01-17T13:05:33+00:00

Previously, both the definition of __PYTHON_EL_get_completions
and the call to __PYTHON_EL_get_completions were sent to the
inferior Python each time
'python-shell-completion-get-completions' was executed.
However, there is no need to send the definition every time as
long as the definition remains unchanged.  We improved this so
that the definition of __PYTHON_EL_get_completions is only sent
during the inferior Python initialization; it is no longer sent
during 'python-shell-completion-get-completions' execution.
* lisp/progmodes/python.el
(python-shell-completion-send-setup-code): New function.
(python-shell-first-prompt-hook): Add the above new function.
(python-shell-completion-get-completions): Omit sending
'python-shell-completion-setup-code'.  (Bug#80182)

Do not use codecs.open for Python 3

2026-01-03T09:52:48+00:00

* lisp/progmodes/python.el (python-shell-eval-file-setup-code):
For Python 3, use built-in open instead of codecs.open to address the
deprecation of codecs.open in Python 3.14.  (Bug#79723)

Improve python-shell-completion-get-completions

2026-01-03T09:51:36+00:00

In 'python-shell-completion-get-completions', since output from the
inferior Python is expected to be in JSON format, commands being echoed
back or warning messages being output caused parsing errors.  We
improved this by re-parsing only the last line when a parsing error
occurs, preventing echo-back or warning messages from affecting parsing.

* lisp/progmodes/python.el
(python-shell-completion-get-completions): Improved to re-parse
only the last line when a JSON parse error occurs.  (Bug#79723)

Fix specification of 'python-indent-guess-indent-offset-verbose'

2025-12-28T17:56:14+00:00

* lisp/progmodes/python.el (python-indent-guess-indent-offset-verbose):
Fix typo in configuration of safe value function.  (Bug#80085)
