| 19:35 | fix unicode glitch in DCS strings, patch by Tim Allen Reported on the mailinglist: " I discovered recently that if an application running inside st tries to send a DCS string, subsequent Unicode characters get messed up. For example, consider the following test-case: printf '\303\277\033P\033\\\303\277' ...where: - \303\277 is the UTF-8 encoding of U+00FF LATIN SMALL LETTER Y WITH DIAERESIS (ÿ). - \033P is ESC P, the token that begins a DCS string. - \033\\ is ESC \, a token that ends a DCS string. - \303\277 is the same ÿ character again. If I run the above command in a VTE-based terminal, or xterm, or QTerminal, or pterm (PuTTY), I get the output: ÿÿ ...which is to say, the empty DCS string is ignored. However, if I run that command inside st (as of commit 9ba7ecf), I get: ÿÿ ...where those last two characters are \303\277 interpreted as ISO8859-1 characters, instead of UTF-8. I spent some time tracing through the state machines in st.c, and so far as I can tell, this is how it works currently: - ESC P sets the "ESC_DCS" and "ESC_STR" flags, indicating that incoming bytes should be collected into the strescseq buffer, rather than being interpreted. - ESC \ sets the "ESC_STR_END" flag (when ESC is received), and then calls strhandle() (when \ is received) to interpret the collected bytes. - If the collected bytes begin with 'P' (i.e. if this was a DCS string) strhandle() sets the "ESC_DCS" flag again, confusing the state machine. If my understanding is correct, fixing the problem should be as easy as removing the line that sets ESC_DCS from strhandle(): diff --git a/st.c b/st.c index ef8abd5..b5b805a 100644 --- a/st.c +++ b/st.c @@ -1897,7 +1897,6 @@ strhandle(void) xsettitle(strescseq.args[0]); return; case 'P': /* DCS -- Device Control String */ - term.mode |= ESC_DCS; case '_': /* APC -- Application Program Command */ case '^': /* PM -- Privacy Message */ return; I've tried the above patch and it fixes my problem, but I don't know if it introduces any others.

| 20:06 | config.def.h: add an option allowwindowops, by default off (secure) Similar to the xterm AllowWindowOps option, this is an option to allow or disallow certain (non-interactive) operations that can be insecure or exploited. NOTE: xsettitle() is not guarded by this because st does not support printing the window title. Else this could be exploitable (arbitrary code execution). Similar problems have been found in the past in other terminal emulators. The sequence for base64-encoded clipboard copy is now guarded because it allows a sequence written to the terminal to manipulate the clipboard of the running user non-interactively, for example: printf '\x1b]52;0;ZWNobyBoaQ0=\a' check-in: a7ffd00bbf user: hiltjo@codemadness.org tags: trunk, origin/split | |

| 19:06 | Revert "support REP (repeat) escape sequence" This reverts commit e8392b282c2eaa28725241a9612804fb55113da4. There is currently a bug in older ncurses versions (like on OpenBSD) where a fix for a bug with REP is not backported yet. Most likely in tty/tty_update.c: Noticed while using lynx (which uses ncurses/curses). To reproduce using lynx: echo "Z0000000" | lynx -stdin or using the program: int main(void) { WINDOW *win; win = initscr(); printw("Z0000000"); refresh(); sleep(5); return 0; } This prints "ZZZZZZZ" (incorrectly). check-in: b6493b97ed user: hiltjo@codemadness.org tags: trunk, origin/split | |
| 12:08 | support REP (repeat) escape sequence The sequence \e[Nb prints the last printed char N (more) times if it's printable, and it's ignored after newline or other control chars. This is Ecma-048/ANSI-X3.6 sequence and not DEC VT. It's supported by xterm, and ncurses uses it when possible, e.g. when TERM is xterm* (and with this commit also st*). xterm supports only codepoints<=255, possibly due to internal limits. We support any value/codepoint which was placed in a cell. To test: - tput rep 65 4 -> prints 'AAAA' - printf "\342\225\246\033[4b" -> prints U+2566 1+4 times. check-in: 41fd4ee033 user: hiltjo@codemadness.org tags: trunk, origin/split | |

| 10:37 | Make shift+wheel behaves as shift+Prev/Next St uses a very good hack where mouse wheel genereates ^Y and ^E, that are the same keys that less and vi uses for backward and fordward scrolling. Scroll, as many terminal emulators, use shift+Prev/Next for scrolling, but it is also using ^E and ^Y for scroling, characters that are reserved in the POSIX shell in emacs mode for end of line and yanking, making scroll unsable in st. This patch adds a new hack, making shift+wheel returning the same sequences than shift+Prev/Next, meaning that scroll or any other similar program will not be able to differentiate between them. check-in: 7df6d552eb user: hiltjo@codemadness.org tags: trunk, origin/split | |

| 12:07 | fix for incorrect (partial) written sequences when libc wcwidth() == -1 Fix an issue with incorrect (partial) written sequences when libc wcwidth() == -1. The sequence is updated to on wcwidth(u) == -1: c = "\357\277\275" but len isn't. A way to reproduce in practise: * st -o dump.txt * In the terminal: printf '\xcd\xb8' - This is codepoint 888, on OpenBSD it reports wcwidth() == -1. - Quit the terminal. - Look in dump.txt (partial written sequence of "UTF_INVALID"). This was introduced in: " commit 11625c7166b7e4dad414606227acec2de1c36464 Author: czarkoff@gmail.com <czarkoff@gmail.com> Date: Tue Oct 28 12:55:28 2014 +0100 Replace character with U+FFFD if wcwidth() is -1 Helpful when new Unicode codepoints are not recognized by libc." Change: Remove setting the sequence. If this happens to break something, another solution could be setting len = 3 for the sequence. check-in: 52af3752e9 user: hiltjo@codemadness.org tags: trunk, origin/split | |

| 11:53 | auto-sync: draw on idle to avoid flicker/tearing st could easily tear/flicker with animation or other unattended output. This commit eliminates most of the tear/flicker. Before this commit, the display timing had two "modes": - Interactively, st was waiting fixed `1000/xfps` ms after forwarding the kb/mouse event to the application and before drawing. - Unattended, and specifically with animations, the draw frequency was throttled to `actionfps`. Animation at a higher rate would throttle and likely tear, and at lower rates it was tearing big frames (specifically, when one `read` didn't get a full "frame"). The interactive behavior was decent, but it was impossible to get good unattended-draw behavior even with carefully chosen configuration. This commit changes the behavior such that it draws on idle instead of using fixed latency/frequency. This means that it tries to draw only when it's very likely that the application has completed its output (or after some duration without idle), so it mostly succeeds to avoid tear, flicker, and partial drawing. The config values minlatency/maxlatency replace xfps/actionfps and define the range which the algorithm is allowed to wait from the initial draw-trigger until the actual draw. The range enables the flexibility to choose when to draw - when least likely to flicker. It also unifies the interactive and unattended behavior and config values, which makes the code simpler as well - without sacrificing latency during interactive use, because typically interactively idle arrives very quickly, so the wait is typically minlatency. While it only slighly improves interactive behavior, for animations and other unattended-drawing it improves greatly, as it effectively adapts to any [animation] output rate without tearing, throttling, redundant drawing, or unnecessary delays (sounds impossible, but it works). check-in: 1bf7292ac2 user: hiltjo@codemadness.org tags: trunk, origin/split | |

| 13:23 | Add terminfo entries for backspace mode St used to use backspace as BS until the commit 230d0c8, but due to general lack of knowledge of lusers, we moved to the most common configuration in linux to avoid answering the same question 3 times per month. With the most common configuration we have a backspace that returns a DEL, and we have a Delete key that doesn't return a DEL character neither a BS. When dealing with devices connected using a serial line (or even with Plan9) it is more common Backspace as BS and Delete as DEL. For this reason, st is not always the best tool when you talk with a serial device. This patch adds new terminfo entries for Backspace as BS and Delete as DEL. A patch for confg.h is also added, to make easier switch between both configurations. check-in: 0c1c6aff7a user: hiltjo@codemadness.org tags: trunk, origin/split | |

| 12:41 | mouseshortcuts: fix custom modifier on release This line didn't work at mshortcuts at config.h: /* mask button function arg release */ { ShiftMask, Button2, selpaste, {.i = 0}, 1 }, and now it does work. The issue was that XButtonEvent.state is "the logical state ... just prior to the event", which means that on release the state has the Button2Mask bit set because button2 was down just before it was released. The issue didn't manifest with the default shift + middle-click on release (to override mouse mode) because its specified modifier is XK_ANY_MOD, at which case match(...) ignores any specific bits and simply returns true. The issue also doesn't manifest on press, because prior to the event Button<N> was not down and its mask bit is not set. Fix by filtering out the mask of the button which we're currently matching. We could have said "well, that's how button events behave, you should use ShiftMask|Button2Mask for release", but this both not obvious to figure out, and specifically here always filtering does not prevent configuring any useful modifiers combination. So it's a win-win. check-in: ca3037e15b user: hiltjo@codemadness.org tags: trunk, origin/split | |
