New submission from bru: The "readline" module offers "write_history_file" from readline/history.h "write_history", but there's no "append_history_file" that would invoke "append_history" from the C header.
This causes inconveniences when saving history to a file (like shown there: https://docs.python.org/3.5/library/readline.html?highlight=readline#example). Indeed, say you have 2 interpreters (A) and (B) open. - (A) and (B) load the history, composed of (z) lines - you work on both, writing (a) lines in (A) and (b) lines in (b) - you close (A), the history file now has (z)+(a) - you close (B), the history file now has (z)+(b) Therefore (A) history (the (a) lines) is lost. Offering "append_history_file" would be a nice way to fix this problem: having (z)+(a)+(b) in the end would be easy. This is exactly what the attached patch does. With it are tests, doc and an example. I've not updated Misc/NEWS yet though (no issue #). ---------- components: Library (Lib) files: 0001-Add-readline.append_history_file-function.patch keywords: patch messages: 231661 nosy: bru priority: normal severity: normal status: open title: readline does not offer partial saves type: enhancement versions: Python 3.5 Added file: http://bugs.python.org/file37275/0001-Add-readline.append_history_file-function.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22940> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
