* [3.13] gh-120221: Support KeyboardInterrupt in asyncio REPL (GH-123795) ↵Miss Islington (bot)2024-09-061-2/+13
| | | | | | | | | | | | | | (#123799) This switches the main pyrepl event loop to always be non-blocking so that it can listen to incoming interruptions from other threads. This also resolves invalid display of exceptions from other threads (gh-123178). This also fixes freezes with pasting and an active input hook.

Drawing something to the screen once per line strikes a balance between perceived responsiveness and performance. * Remove dead code from pyrepl `msg_at_bottom` is always true. * Speed up pyrepl's screen rendering computation The Reader in pyrepl doesn't hold a complete representation of the screen area being drawn as persistent state. Instead, it recomputes it, on each keypress. This is fast enough for a few hundred bytes, but incredibly slow as the input buffer grows into the kilobytes (likely because of pasting). Rather than making some expensive and expansive changes to the repl's internal representation of the screen, add some caching: remember some data from one refresh to the next about what was drawn to the screen and, if we don't find anything that has invalidated the results that were computed last time around, reuse them. To keep this caching as simple as possible, all we'll do is look for lines in the buffer that were above the cursor the last time we were asked to update the screen, and that are still above the cursor now. We assume that nothing can affect a line that comes before both the old and new cursor location without us being informed. Based on this assumption, we can reuse old lines, which drastically speeds up the overwhelmingly common case where the user is typing near the end of the buffer. * Speed up pyrepl prompt drawing Cache the `can_colorize()` call rather than repeatedly recomputing it. This call looks up an environment variable, and is called once per character typed at the REPL. The environment variable lookup shows up as a hot spot when profiling, and we don't expect this to change while the REPL is running. * Speed up pasting multiple lines into the REPL Previously, we were checking whether the command should be accepted each time a line break was encountered, but that's not the expected behavior. In bracketed paste mode, we expect everything pasted to be part of a single block of code, and encountering a newline shouldn't behave like a user pressing <Enter> to execute a command. The user should always have a chance to review the pasted command before running it. * Use a read buffer for input in pyrepl Previously we were reading one byte at a time, which causes much slower IO than necessary. Instead, read in chunks, processing previously read data before asking for more. * Optimize finding width of a single character `wlen` finds the width of a multi-character string by adding up the width of each character, and then subtracting the width of any escape sequences. It's often called for single character strings, however, which can't possibly contain escape sequences. Optimize for that case. * Optimize disp_str for ASCII characters Since every ASCII character is known to display as single width, we can avoid not only the Unicode data lookup in `disp_str` but also the one hidden in `str_width` for them. * Speed up cursor movements in long pyrepl commands When the current pyrepl command buffer contains many lines, scrolling up becomes slow. We have optimizations in place to reuse lines above the cursor position from one refresh to the next, but don't currently try to reuse lines below the cursor position in the same way, so we wind up with quadratic behavior where all lines of the buffer below the cursor are recomputed each time the cursor moves up another line. Optimize this by only computing one screen's worth of lines beyond the cursor position. Any lines beyond that can't possibly be shown by the console, and bounding this makes scrolling up have linear time complexity instead. --------- (cherry picked from commit 32a0faba439b239d7b0c242c1e3cd2025c52b8cf) Signed-off-by: Matt Wozniski <mwozniski@bloomberg.net> Co-authored-by: Matt Wozniski <mwozniski@bloomberg.net> Co-authored-by: Pablo Galindo <pablogsal@gmail.com>
