I can reproduce this in all the Emacs builds I have, including this 29.0.50 build. ;; With a short timeout causing the request to be aborted: (url-retrieve-synchronously "http://www.example.com" nil nil 0.01) nil M-x list-processes www.example.com -- open -- -- Main (network connection to www.example.com:80) C-x C-c Active processes exist; kill them and exit anyway? (yes or no) ;; With a long timeout (or a nil timeout): (url-retrieve-synchronously "http://www.example.com" nil nil 5) # M-x list-processes www.example.com -- open -- -- Main (network connection to www.example.com:80) C-x C-c exits without any process-related prompt I'm not sure why the network connection remains open in either case, but regardless of that it seems as if process-query-on-exit-flag is set if the request times out, and cleared if it does not. The query-on-exit case seems to me like a bug, especially when there is no obvious way to obtain the process object and change the flag. I found bug #34607 when searching, but I don't understand what's being discussed there; especially the example code for this: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=34607#22 which seems to me like it would be signalling an error when it winds up evaluating (with-current-buffer nil ...) -Phil In GNU Emacs 29.0.50 (build 4, x86_64-pc-linux-gnu, X toolkit, cairo version 1.15.10, Xaw scroll bars) of 2022-07-15 built on phil-lp Repository revision: 00eb894a56d63fad3573a53dd57c323289711512 Repository branch: master Windowing system distributor 'The X.Org Foundation', version 11.0.12008000 System Description: Ubuntu 18.04.6 LTS Configured using: 'configure --prefix=/home/phil/emacs/trunk/usr/local --with-x-toolkit=lucid --without-sound '--program-transform-name=s/^ctags$/ctags_emacs/'' Configured features: CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ JPEG JSON LCMS2 LIBXML2 MODULES NOTIFY INOTIFY PDUMPER PNG RSVG SECCOMP THREADS TIFF TOOLKIT_SCROLL_BARS WEBP X11 XDBE XIM XINPUT2 XPM LUCID ZLIB Important settings: value of $LC_MONETARY: en_NZ.UTF-8 value of $LC_NUMERIC: en_NZ.UTF-8 value of $LC_TIME: en_NZ.UTF-8 value of $LANG: en_GB.UTF-8 value of $XMODIFIERS: @im=ibus locale-coding-system: utf-8-unix Major mode: Lisp Interaction Minor modes in effect: savehist-mode: t windmove-mode: t winner-mode: t tooltip-mode: t global-eldoc-mode: t eldoc-mode: t show-paren-mode: t electric-indent-mode: t mouse-wheel-mode: t tool-bar-mode: t menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t line-number-mode: t indent-tabs-mode: t transient-mark-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t Load-path shadows: None found.
