[issue12627] Implement PEP 394: The "python" Command on Unix-Like Systems
New submission from Kerrick Staley : This issue was opened to track the implementation of PEP 394, which governs the way the python command and commands like python2 and python3 work on Unix-like systems. -- components: Installation messages: 141034 nosy: Kerrick.Staley priority: normal severity: normal status: open title: Implement PEP 394: The "python" Command on Unix-Like Systems type: feature request versions: Python 2.7, Python 3.3 ___ Python tracker <http://bugs.python.org/issue12627> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12627] Implement PEP 394: The "python" Command on Unix-Like Systems
Kerrick Staley added the comment: Here is a patch that will update the Makefile.pre.in file for 2.7, causing it to install python2 and python2-config when run with "make install" (or just "make bininstall"). This does not update any documentation. Also, it appears that Idle and PyDoc are not installed by the 2.7 Makefile, so I didn't do anything about those, even though the PEP mentions them. -- keywords: +patch Added file: http://bugs.python.org/file22737/version27_links.patch ___ Python tracker <http://bugs.python.org/issue12627> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Kerrick Staley added the comment: This updates the links created by "make install" or "make bininstall" in Python 3 so that they're in agreement with the recommendations of PEP 394; it's the equivalent of version27_links.patch but is for Python 3. -- Added file: http://bugs.python.org/file22738/version33_links.patch ___ Python tracker <http://bugs.python.org/issue12627> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue40403] pdb does not drop into debugger upon SyntaxError caused by ast.literal_eval
New submission from Kerrick Staley :
Summary:
When you call ast.literal_eval on a string that does not contain valid Python
code, it raises a SyntaxError. This causes pdb to exit instead of stopping
execution at the point that the SyntaxError was raised.
To reproduce:
1. Create a Python file foo.py with these contents:
import ast
ast.literal_eval('')
2. Run python -m pdb foo.py
3. Type 'c' and hit enter.
Expected behavior:
pdb drops into a shell in ast.py at the point where the SyntaxError occurred.
Actual behavior:
The program exits, and a SyntaxError traceback is displayed.
System configuration:
Python 3.8.2 on Arch Linux.

[issue41096] Need command to exit PDB interactive shell
New submission from Kerrick Staley : In PDB, when you use "interact" to enter an interactive shell, the only way to exit that shell is to send an end-of-transmission (Ctrl+D) character. In some environments, such as Jupyter, this is awkward to do. Here is a StackOverflow post where a user encountered this issue: https://stackoverflow.com/questions/47522316/exit-pdb-interactive-mode-from-jupyter-notebook/62546186 I think that the user should be able to type quit() in order to exit the interactive Python shell and go back to the PDB shell, similar to a regular interactive Python session. I think you should also support exit() because the Python shell supports that one as well (quit() and exit() do the same thing, I think the alias exists to help discoverability for new users). I confirmed this issue on Python 3.6.9 and 3.8.3. -- components: Library (Lib) messages: 372226 nosy: Kerrick Staley priority: normal severity: normal status: open title: Need command to exit PDB interactive shell type: enhancement versions: Python 3.6, Python 3.7, Python 3.8 ___ Python tracker <https://bugs.python.org/issue41096> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue41096] Need command to exit PDB interactive shell
Kerrick Staley added the comment: Serhiy: I'm referring to the interactive mode that can be entered by typing "interact" in PDB. Here are reproduction instructions: 1. Run "python3" command. 2. In Python shell, type "import pdb; pdb.set_trace()". 3. In PDB shell, type "interact". Now, in this "PDB InteractiveConsole" shell (I'm not sure what it's called), the only way to go back to PDB is to press Ctrl+D. If you type "quit()" or "exit()" it exits the entire Python process. If you type "q" it says "NameError: name 'q' is not defined". In Jupyter, I get different (but still undesirable) behavior: "quit()" raises "NameError: name 'quit' is not defined" (and similar for "exit()"). I think "quit()"/"exit()" in these contexts should return you back to the PDB shell. -- ___ Python tracker <https://bugs.python.org/issue41096> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue41930] Wrap sqlite3_serialize API in sqlite3 module
New submission from Kerrick Staley :
It would be useful to provide a wrapper (in the Python sqlite3 stdlib module)
for the sqlite3_serialize API. This API allows you to get a database's content
as a byte string, as if you had called open('foo.sqlite3', 'rb').read().
sqlite3_serialize can even be used for :memory: databases, which I think is the
most interesting use-case.
Concretely, I'd propose adding a .serialize() method on sqlite3.Connection
objects that returns a bytes object representing the serialized database. It
would be similar to the .iterdump() method except that it would use the binary
format instead of the text format, and it would return all the data at once
instead of an iterator (because that's how the underlying sqlite API works).
