From 8806b6e2379372900e3d9e0bf6604bc7f727350b Mon Sep 17 00:00:00 2001 From: Chris Down Date: Thu, 17 Mar 2022 15:56:13 +0000 Subject: manage: propertynotify: Reduce cost of unused size hints 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and currently all of these result in a separate updatesizehints() call, of which all but the final one are immediately outdated.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. --- dwm.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/dwm.c b/dwm.c index 5f16260..d8075ad 100644 --- a/dwm.c +++ b/dwm.c @@ -89,7 +89,7 @@ struct Client { float mina, maxa; int x, y, w, h; int oldx, oldy, oldw, oldh; - int basew, baseh, incw, inch, maxw, maxh, minw, minh; + int basew, baseh, incw, inch, maxw, maxh, minw, minh, hintsvalid; int bw, oldbw; unsigned int tags; int isfixed, isfloating, isurgent, neverfocus, oldstate, isfullscreen; @@ -345,6 +345,8 @@ applysizehints(Client *c, int *x, int *y, int *w, int *h, int interact) if (*w < bh) *w = bh; if (resizehints || c->isfloating || !c->mon->lt[c->mon->sellt]->arrange) { + if (!c->hintsvalid) + updatesizehints(c); /* see last two sentences in ICCCM 4.1.2.3 */ baseismin = c->basew == c->minw && c->baseh == c->minh; if (!baseismin) { /* temporarily remove base dimensions */ @@ -1059,7 +1061,6 @@ manage(Window w, XWindowAttributes *wa) XSetWindowBorder(dpy, w, scheme[SchemeNorm][ColBorder].pixel); configure(c); /* propagates border_width, if size doesn't change */ updatewindowtype(c); - updatesizehints(c); updatewmhints(c); XSelectInput(dpy, w, EnterWindowMask|FocusChangeMask|PropertyChangeMask|StructureNotifyMask); grabbuttons(c, 0); @@ -1233,7 +1234,7 @@ propertynotify(XEvent *e) arrange(c->mon); break; case XA_WM_NORMAL_HINTS: - updatesizehints(c); + c->hintsvalid = 0; break; case XA_WM_HINTS: updatewmhints(c); @@ -1989,6 +1990,7 @@ updatesizehints(Client *c) } else c->maxa = c->mina = 0.0; c->isfixed = (c->maxw && c->maxh && c->maxw == c->minw && c->maxh == c->minh); + c->hintsvalid = 1; } void -- cgit v1.2.3-70-g09d2 From d93ff48803f04f1363bf303af1d7e6ccc5cb8d3f Mon Sep 17 00:00:00 2001 From: Santtu Lakkala Date: Mon, 21 Feb 2022 16:58:28 +0200 Subject: Update monitor positions also on removal When monitors are removed, the coordinates of existing monitors may change, if the removed monitors had smaller coordinates than the remaining ones.

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. --- dwm.c | 1 + 1 file changed, 1 insertion(+) diff --git a/dwm.c b/dwm.c index b3c43ee..c0c3b9b 100644 --- a/dwm.c +++ b/dwm.c @@ -1780,6 +1780,7 @@ unmanage(Client *c, int destroyed) wc.border_width = c->oldbw; XGrabServer(dpy); /* avoid race conditions */ XSetErrorHandler(xerrordummy); + XSelectInput(dpy, c->win, NoEventMask); XConfigureWindow(dpy, c->win, CWBorderWidth, &wc); /* restore border */ XUngrabButton(dpy, AnyButton, AnyModifier, c->win); setclientstate(c, WithdrawnState); -- cgit v1.2.3-70-g09d2 From 5b2e5e7a4001479e4dc3e245f96e49f7ea0da658 Mon Sep 17 00:00:00 2001 From: explosion-mental Date: Fri, 29 Jul 2022 18:26:04 -0500 Subject: spawn: reduce 2 lines, change fprintf() + perror() + exit() to die("... :") when calling die and the last character of the string corresponds to ':', die() will call perror().

Also `c` is set to `selmon->sel` so we can use `c` in the first check instead which makes things shorter. --- dwm.c | 23 ++++++++--------------- 1 file changed, 8 insertions(+), 15 deletions(-) diff --git a/dwm.c b/dwm.c index 61713b7..967c9e8 100644 --- a/dwm.c +++ b/dwm.c @@ -918,13 +918,11 @@ gettextprop(Window w, Atom atom, char *text, unsigned int size) text[0] = '\0'; if (!XGetTextProperty(dpy, w, &name, atom) || !name.nitems) return 0; - if (name.encoding == XA_STRING) + if (name.encoding == XA_STRING) { strncpy(text, (char *)name.value, size - 1); - else { - if (XmbTextPropertyToTextList(dpy, &name, &list, &n) >= Success && n > 0 && *list) { - strncpy(text, *list, size - 1); - XFreeStringList(list); - } + } else if (XmbTextPropertyToTextList(dpy, &name, &list, &n) >= Success && n > 0 && *list) { + strncpy(text, *list, size - 1); + XFreeStringList(list); } text[size - 1] = '\0'; XFree(name.value); @@ -1099,9 +1097,7 @@ maprequest(XEvent *e) static XWindowAttributes wa; XMapRequestEvent *ev = &e->xmaprequest; - if (!XGetWindowAttributes(dpy, ev->window, &wa)) - return; - if (wa.override_redirect) + if (!XGetWindowAttributes(dpy, ev->window, &wa) || wa.override_redirect) return; if (!wintoclient(ev->window)) manage(ev->window, &wa); @@ -1603,7 +1599,6 @@ setup(void) focus(NULL); } - void seturgent(Client *c, int urg) { @@ -2124,12 +2119,10 @@ zoom(const Arg *arg) { Client *c = selmon->sel; - if (!selmon->lt[selmon->sellt]->arrange - || (selmon->sel && selmon->sel->isfloating)) + if (!selmon->lt[selmon->sellt]->arrange || !c || c->isfloating) + return; + if (c == nexttiled(selmon->clients) && !(c = nexttiled(c->next))) return; - if (c == nexttiled(selmon->clients)) - if (!c || !(c = nexttiled(c->next))) - return; pop(c); } -- cgit v1.2.3-70-g09d2 From e0dee911455cee739a5b05a994828f4a37a2764d Mon Sep 17 00:00:00 2001 From: Hiltjo Posthuma Date: Mon, 8 Aug 2022 10:43:09 +0200 Subject: sync code-style patch from libsl --- util.c | 23 ++++++++++++----------- 1 file changed, 12 insertions(+), 11 deletions(-) diff --git a/util.c b/util.c index fe044fc..96b82c9 100644 --- a/util.c +++ b/util.c @@ -6,18 +6,9 @@ #include "util.h" -void * -ecalloc(size_t nmemb, size_t size) -{ - void *p; - - if (!(p = calloc(nmemb, size))) - die("calloc:"); - return p; -} - void -die(const char *fmt, ...) { +die(const char *fmt, ...) +{ va_list ap; va_start(ap, fmt); @@ -33,3 +24,13 @@ die(const char *fmt, ...) { exit(1); } + +void * +ecalloc(size_t nmemb, size_t size) +{ + void *p; + + if (!(p = calloc(nmemb, size))) + die("calloc:"); + return p; +} -- cgit v1.2.3-70-g09d2 From a859676ead17017bbe81b4989b2f2e0b00a0b4ba Mon Sep 17 00:00:00 2001 From: Stein Date: Tue, 9 Aug 2022 10:38:08 +0200 Subject: Simplify client y-offset correction 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. --- dwm.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/dwm.c b/dwm.c index 967c9e8..87d0ada 100644 --- a/dwm.c +++ b/dwm.c @@ -1049,9 +1049,7 @@ manage(Window w, XWindowAttributes *wa) if (c->y + HEIGHT(c) > c->mon->my + c->mon->mh) c->y = c->mon->my + c->mon->mh - HEIGHT(c); c->x = MAX(c->x, c->mon->mx); - /* only fix client y-offset, if the client center might cover the bar */ - c->y = MAX(c->y, ((c->mon->by == c->mon->my) && (c->x + (c->w / 2) >= c->mon->wx) - && (c->x + (c->w / 2) < c->mon->wx + c->mon->ww)) ? bh : c->mon->my); + c->y = MAX(c->y, c->mon->wy); c->bw = borderpx; wc.border_width = c->bw; -- cgit v1.2.3-70-g09d2 From 44adafe0069e73aa03a3829d7bb39591cd8b3f1d Mon Sep 17 00:00:00 2001 From: Stein Date: Thu, 11 Aug 2022 11:15:55 +0200 Subject: Make floating windows spawn within the monitor's window area 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. --- dwm.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/dwm.c b/dwm.c index 87d0ada..f2bc4ba 100644 --- a/dwm.c +++ b/dwm.c @@ -1044,11 +1044,11 @@ manage(Window w, XWindowAttributes *wa) applyrules(c); } - if (c->x + WIDTH(c) > c->mon->mx + c->mon->mw) - c->x = c->mon->mx + c->mon->mw - WIDTH(c); - if (c->y + HEIGHT(c) > c->mon->my + c->mon->mh) - c->y = c->mon->my + c->mon->mh - HEIGHT(c); - c->x = MAX(c->x, c->mon->mx); + if (c->x + WIDTH(c) > c->mon->wx + c->mon->ww) + c->x = c->mon->wx + c->mon->ww - WIDTH(c); + if (c->y + HEIGHT(c) > c->mon->wy + c->mon->wh) + c->y = c->mon->wy + c->mon->wh - HEIGHT(c); + c->x = MAX(c->x, c->mon->wx); c->y = MAX(c->y, c->mon->wy); c->bw = borderpx; -- cgit v1.2.3-70-g09d2
