* Makefile: remove the options targetHEADmasterHiltjo Posthuma2023-09-221-8/+2
| | | | | | | | | | | The Makefile used to suppress output (by using @), so this target made sense at the time. But the Makefile should be simple and make debugging with less abstractions or fancy printing. The Makefile was made verbose and doesn't hide the build output, so remove this target. Prompted by a question on the mailing list about the options target.
* restore SIGCHLD sighandler to default before spawning a programHiltjo Posthuma2023-04-091-0/+8
| | | | | | | | | | | | | | | | | | From sigaction(2): A child created via fork(2) inherits a copy of its parent's signal dispositions. During an execve(2), the dispositions of handled signals are reset to the default; the dispositions of ignored signals are left unchanged. This refused to start directly some programs from configuring in config.h: static Key keys[] = { MODKEY, XK_o, spawn, {.v = cmd } }, }; Some reported programs that didn't start were: mpv, anki, dmenu_extended. Reported by pfx. Initial patch suggestion by Storkman.
* config.mk: update to _XOPEN_SOURCE=700LNRK2023-02-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | SA_NOCLDWAIT is marked as XSI in the posix spec [0] and FreeBSD and NetBSD seems to more be strict about the feature test macro [1]. so update the macro to use _XOPEN_SOURCE=700L instead, which is equivalent to _POSIX_C_SOURCE=200809L except that it also unlocks the X/Open System Interfaces.

* Use sigaction(SA_NOCLDWAIT) for SIGCHLD handlingChris Down2023-01-281-11/+9
| | | | | | | | | | | | | | | | | | | | | | | | signal() semantics are pretty unclearly specified. For example, depending on OS kernel and libc, the handler may be returned to SIG_DFL (hence the inner call to read the signal handler). Moving to sigaction() means the behaviour is consistently defined. Using SA_NOCLDWAIT also allows us to avoid calling the non-reentrant function die() in the handler. Some addditional notes for archival purposes: * NRK pointed out errno of waitpid could also theoretically get clobbered. * The original patch was iterated on and modified by NRK and Hiltjo: * SIG_DFL was changed to SIG_IGN, this is required, atleast on older systems such as tested on Slackware 11. * signals are not blocked using sigprocmask, because in theory it would briefly for example also ignore a SIGTERM signal. It is OK if waitpid() is (in theory interrupted). POSIX reference: "Consequences of Process Termination": https://pubs.opengroup.org/onlinepubs/9699919799/functions/_Exit.html#tag_16_01_03_01
* grabkeys: Avoid missing events when a keysym maps to multiple keycodesChris Down2022-12-071-7/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | It's not uncommon for one keysym to map to multiple keycodes. For example, the "play" button on my keyboard sends keycode 172, but my bluetooth headphones send keycode 208, both of which map back to XF86AudioPlay: % xmodmap -pke | grep XF86AudioPlay keycode 172 = XF86AudioPlay XF86AudioPause XF86AudioPlay XF86AudioPause keycode 208 = XF86AudioPlay NoSymbol XF86AudioPlay keycode 215 = XF86AudioPlay NoSymbol XF86AudioPlay This is a problem because the current code only grabs a single one of these keycodes, which means that events for any other keycode also mapping to the bound keysym will not be handled by dwm. In my case, this means that binding XF86AudioPlay does the right thing and correctly handles my keyboard's keys, but does nothing on my headphones. I'm not the only person affected by this, there are other reports[0]. In order to fix this, we look at the mappings between keycodes and keysyms at grabkeys() time and pick out all matching keycodes rather than just the first one. The keypress() side of this doesn't need any changes because the keycode gets converted back to a canonical keysym before any action is taken. 0: https://github.com/cdown/dwm/issues/11

* Remove dmenumon variableStein2022-08-282-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reasoning: Since 2011 dmenu has been capable of working out which monitor currently has focus in a Xinerama setup, making the use of the -m flag more or less redundant. This is easily demonstrated by using dmenu in any other window manager. There used to be a nodmenu patch that provided these changes: https://git.suckless.org/sites/commit/ed68e3629de4ef2ca2d3f8893a79fb570b4c0cbc.html but this was removed on the basis that it was very easy to work out and apply manually if needed. The proposal here is to remove this dependency from dwm. The mechanism of the dmenumon variable could be provided via a patch if need be. The edge case scenario that dmenu does not handle on its own, and the effect of removing this mechanism, is that if the user trigger focusmon via keybindings to change focus to another monitor that has no clients, then dmenu will open on the monitor containing the window with input focus (or the monitor with the mouse cursor if no windows have input focus). If this edge case is important to cover then this can be addressed by setting input focus to selmon->barwin in the focus function if there is no client to give focus to (rather than giving focus back to the root window).
* config.def.h: make keys and buttons constNRK2022-08-191-2/+2
| | | | | pretty much all other variables are declared as const when they're not modified.
* Remove blw variable in favour of calculating the value when neededStein2022-08-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | The purpose and reasoning behind the bar layout width (blw) variable in dwm the way it is today may not be immediately obvious. The use of the variable makes more sense when looking at commit 2ce37bc from 2009 where blw was initialised in the setup function and it represented the maximum of all available layout symbols. for(blw = i = 0; LENGTH(layouts) > 1 && i < LENGTH(layouts); i++) { w = TEXTW(layouts[i].symbol); blw = MAX(blw, w); } As such the layout symbol back then was fixed in size and both drawbar and buttonpress depended on this variable. The the way the blw variable is set today in drawbar means that it merely caches the size of the layout symbol for the last bar drawn. While unlikely to happen in practice it is possible that the last bar drawn is not that of the currently selected monitor, which can result in misaligned button clicks if there is a difference in layout symbol width between monitors.
* Make floating windows spawn within the monitor's window areaStein2022-08-121-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a follow-up on this thread: https://lists.suckless.org/hackers/2208/18462.html The orginal code had constraints such that if a window's starting attributes (position and size) were to place the window outside of the edges of the monitor, then the window would be moved into view at the closest monitor edge. There was an exception to this where if a top bar is used then the window should not obscure the bar if present, which meant to place the window within the window area instead. The proposed change here makes it the general rule that floating windows should spawn within the window area rather than within the monitor area. This makes it simple and consistent with no exceptions and it makes the intention of the code clear. This has the benefit of making the behaviour consistent regardless of whether the user is using a top bar or a bottom bar. Additionally this will have an effect on patches that modify the size of the window area. For example if the insets patch is used to reserve space on the left hand side of the monitor for a dock or a vertical bar then new floating clients will not obscure that area.
* Simplify client y-offset correctionStein2022-08-101-3/+1
| | | | | | | | | | | | | | | | | The reasoning behind the original line may be lost to time as it does not make much sense checking the position on the x-axis to determine how to position the client on the y-axis. In the context of multi-monitor setups the monitor y position (m->my) may be greater than 0 (say 500), in which case the window could be placed out of view if: - the window attributes have a 0 value for the y position and - we end up using the y position of bh (e.g. 22) If the aim is to avoid a new floating client covering the bar then restricting y position to be at least that of the window area (m->wy) should cover the two cases of using a top bar and using a bottom bar.

* code-style: simplify some checksNRK2022-08-061-15/+8
| | | | | | | | | | | | | | | | | | | | | | main change here is making the `zoom()` logic saner. the rest of the changes are just small stuff which accumulated on my local branch. pop() must not be called with NULL. and `zoom()` achieves this, but in a very (unnecessarily) complicated way: if c == NULL then nexttiled() will return NULL as well, so we enter this branch: if (c == nexttiled(selmon->clients)) in here the !c check fails and the function returns before calling pop() if (!c || !(c = nexttiled(c->next))) return; however, none of this was needed. we can simply return early if c was NULL. Also `c` is set to `selmon->sel` so we can use `c` in the first check instead which makes things shorter.

* unmanage: stop listening for events for unmanaged windowsStein2022-08-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is in particular to avoid flickering in dwm (and high CPU usage) when hovering the mouse over a tabbed window that was previously managed by dwm. Consider the following two scenarios: 1) We start tabbed (window 0xc000003), tabbed is managed by the window manager. We start st being embedded into tabbed. $ st -w 0xc000003 What happens here is that: - tabbed gets a MapRequest for the st window - tabbed reparents the st window - tabbed will receive X events for the window The window manager will have no awareness of the st window and the X server will not send X events to the window manager relating to the st window. There is no flickering or any other issues relating to focus. 2) We start tabbed (window 0xc000003), tabbed is managed by the window manager. We start st as normal (window 0xd400005). What happens here is that: - the window manager gets a MapRequest for the st window - dwm manages the st window as a normal client - dwm will receive X events for the window Now we use xdotool to trigger a reparenting of the st window into tabbed. $ xdotool windowreparent 0xd400005 0xc000003 What happens here is that: - tabbed gets a MapRequest for the st window - tabbed reparents the st window - the window manager gets an UnmapNotify - the window manager no longer manages the st window - both the window manager and tabbed will receive X events for the st window In dwm move the mouse cursor over the tabbed window. What happens now is that: - dwm will receive a FocusIn event for the tabbed window - dwm will set input focus for the tabbed window - tabbed will receive a FocusIn event for the main window - tabbed will give focus to the window on the currently selected tab - which again triggers a FocusIn event which dwm receives - dwm determines that the window that the FocusIn event is for (0xd400005) is not the currently selected client (tabbed) - dwm sets input focus for the tabbed window - this causes an infinite loop as long as the mouse cursor hovers the tabbed window, resulting in flickering and high CPU usage The fix here is to tell the X server that we are no longer interested in receiving events for this window when the window manager stops managing the window.

* manage: propertynotify: Reduce cost of unused size hintsChris Down2022-04-161-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch defers all size hint calculations until they are actually needed, drastically reducing the number of calls to updatesizehints(), which can be expensive when called repeatedly (as it currently is during resizes). In my unscientific testing this reduces calls to updatesizehints() by over 90% during a typical work session. There are no functional changes for users other than an increase in responsiveness after resizes and a reduction in CPU time. In slower environments or X servers, this patch also offers an improvement in responsiveness that is often tangible after resizing a client that changes hints during resizes. There are two main motivations to defer this work to the time of hint application: 1. Some clients, especially terminals using incremental size hints, resend XA_WM_NORMAL_HINTS events on resize to avoid fighting with the WM or mouse resizing. For example, some terminals like urxvt clear PBaseSize and PResizeInc during XResizeWindow and restore them afterwards. For this reason, after the resize is concluded, we typically receive a backlogged XA_WM_NORMAL_HINTS message for each update period with movement, which is useless. In some cases one may get hundreds or thousands of XA_WM_NORMAL_HINTS messages on large resizes, and currently all of these result in a separate updatesizehints() call, of which all but the final one are immediately outdated. (We can't just blindly discard these messages during resizes like we do for EnterNotify, because some of them might actually be for other windows, and may not be XA_WM_NORMAL_HINTS events.) 2. For users which use resizehints=0 most of these updates are unused anyway -- in the normal case where the client is not floating these values won't be used, so there's no need to calculate them up front. A synthetic test using the mouse to resize a floating terminal window from roughly 256x256 to 1024x1024 and back again shows that the number of calls to updatesizehints() goes from over 500 before this patch (one for each update interval with movement) to 2 after this patch (one for each hint application), with no change in user visible behaviour. This also reduces the delay before dwm is ready to process new events again after a large resize on such a client, as it avoids the thundering herd of updatesizehints() calls when hundreds of backlogged XA_WM_NORMAL_HINTS messages appear at once after a resize is finished.
* manage: For isfloating/oldstate check/set, ensure trans client actually existsMiles Alan2022-03-131-1/+1
| | | | | | | | In certain instances trans may be set to a window that doesn't actually map to a client via wintoclient; in this case it doesn't make sense to set isfloating/oldstate since trans is essentially invalid in that case / correlates to the above condition check where trans is set / XGetTransientForHint is called.

* drawbar: Don't expend effort drawing bar if it is occludedChris Down2021-12-191-0/+3
| | | | | | | | | | | | | | | | | I noticed that a non-trivial amount of dwm's work on my machine was from drw_text, which seemed weird, because I have the bar disabled and we only use drw_text as part of bar drawing. Looking more closely, I realised that while we use m->showbar when updating the monitor bar margins, but don't skip actually drawing the bar if it is hidden. This patch skips drawing it entirely if that is the case. On my machine, this takes 10% of dwm's on-CPU time, primarily from restack() and focus(). When the bar is toggled on again, the X server will generate an Expose event, and we'll redraw the bar as normal as part of expose().

* Do not allow focus to drift from fullscreen client via focusstack()Chris Down2021-03-291-1/+1
| | | | | | | | | | | | | It generally doesn't make much sense to allow focusstack() to navigate away from the selected fullscreen client, as you can't even see which client you're selecting behind it. I have had this up for a while on the wiki as a separate patch[0], but it seems reasonable to avoid this behaviour in dwm mainline, since I'm struggling to think of any reason to navigate away from a fullscreen client other than a mistake. 0: https://dwm.suckless.org/patches/alwaysfullscreen/
