This way, when changing focus between outputs, the directional focus
command will focus the focused window within the parent container that
is next in the given direction.
Previously, the next window of the given direction was focused which is
Inconsistent with changing focus inside the same output.
Fixes#1160.
Allow enabling forced focus wrapping by specifying "focus_wrapping
force" in i3's configuration. This syntax supersedes the previous
"force_focus_wrapping yes" one, which remains available for backwards
compatibility.
This fixes a crash that occurs when disabling floating for a container
while it is being moved or resized.
@Deiz describes the problem:
> It occurs because the command that disables floating runs before the
event loop. So, the window is tiled, its floating parent is destroyed,
but then a key event is handled which causes the position/size of the
now-destroyed parent to be modified.
Fixes#1627
Applied for:
1. '[...] focus' for a floating container raises it to the top.
2. Focusing a window through a focus event raises it to the top.
Fixes#2572
canonicalize_output_name allowed the "primary" special output name to
be canonicalized, thus converting it to the name of whatever output
was the primary output at the time. This caused settings
(specifically, i3bar output and tray_output settings) to be stored as
specific output names, instead of the intended special names whose
referred output may change as the system's configuration (i.e. current
primary output) changes.
Add a check to canonicalize_output_name to return the name as-is if it
is the special name "primary".
Allow appending 'P' to the fake output specification to set the
created output's "primary" flag, to allow writing test cases that
depend on the presence of a primary output.
fake_outputs_init would unconditionally increase the string read
pointer variable (walk) by one character more than the number of
characters that have been read, to skip past the character delimiting
records (a comma). However, when the input string was not terminated
by a comma, it would cause the function to read past the null
terminator instead.
Avoid this by explicitly checking for the expected delimiter.
fake_outputs_init used a sprintf invocation with a throw-away buffer
to estimate how many characters the sscanf invocation consumed. This
was unnecessary, and also potentially incorrect, as differences
between the read and formatted strings (such as leading zeros) could
lead to fake_outputs_init to lose its track.
Instead, use the %n format specifier which allows saving the number of
characters consumed by sscanf so far. %n is part of C99.
All other message types are verbs, only our first-ever message COMMAND wasn’t.
While we’re here, also change the message type dictionary into a table with
clickable links to the corresponding reply type.
Authors of downstream IPC libraries are encouraged to keep the old name around
so as to not break existing code, but mark it as deprecated.
This fixes a regression introduced in commit
4e88c10564ca5366c2578908f62ec56625a26718: when attempting to move the
single child of a container in the direction of another output, i3
would move the window to the output, despite the window not being at
the edge of its output, instead of moving it to its parent container.
The bug occurred because the check for moving containers across
outputs with non-default workspace layouts (issue #1603) did not
actually verify that the moved window lies at the edge of the
workspace, despite what its comment said.
Fixes issue #2466.
Makes "assign [<criteria>] workspace number <number>" work in the same
manner as "move to workspace number <number>" instead of assigning the
window to a workspace named "number <number>".
config.spec is modified to expect a 'number' string and an extra
argument is used in cfg_assign.
For workspaces that don't exist yet, workspace_get is used as a
fallback. This also allows the user to assign to "<number> <workspace>"
eg "2: work" and the full name will be used if workspace number 2
doesn't exist yet.
Fixes#2590.
This commit also introduces slurp() which reads a file in its entirety. Using
this function instead of doing IO in the functions in load_layout.c again and
again makes the code cleaner (fixing at least two memory leaks) and avoids
re-reading the same file 3 times.

Convert the output names specified in the "output" and "tray_output"
fields in bar blocks in i3's configuration to the referred output's
primary name. This allows specifying names other than the primary
output's name in the given fields without changing the IPC protocol.
In addition to the name of the monitor itself (which is still used as
the i3 output's primary name), register RandR output names associated
with the RandR monitor as alternative i3 output names.
Currently, only one name is ever added, and only the first name is
ever accessed; actually using the capability to store and access
multiple names comes in the following commits.
Currently simply returns output->name, but this will make it easier to
change how output names are stored in the following commits.
Also replace reading output->name with invocations of
output_primary_name. Code which writes output->name is unchanged. Done
using a mostly mechanical replacement of output->name to
output_primary_name(output).
The code in handle_signal() wasn't clearing the struct sigaction before passing it to sigaction().
This meant that we would block a random set of signals while executing the default handler, or jump to the uninitialized __sa_sigaction__ (instead of sa_handler).
Initialize properly as we do in setup_signal_handler().
This fixes the following issue when having an error early in the config file:

This introduces memory usage by one copy of the config file, which is an
acceptable trade-off for being able to easily revert data loss.
The default config is 6KB, user configs will be in the same ballpark.

Subset comparison was introduced with the rather large commit
bf3cd41b5d, but I now think we should use
equality.
In other words, the following key binding:
bindsym Mod4+x nop Mod4+x
previously would have been triggered when pressing Mod3+Mod4+x.
Strictly speaking, this is a change of behavior, but it breaks none of our
tests, and using equality instead of subset comparison enables more use-cases.

This patch fixes the issue #2511(https://github.com/i3/i3/issues/2511).
1). Memorize the marks, but only call con_mark once the container has finished parsing. (Credit: This is @Airblader's patch.)
2). Add a test case 267-regress-mark-restart.t for regression test to check if mark and restart command crash i3.
This introduces the flag --exclude-titlebar for mouse bindings which
allows bindings like
bindsym --whole-window --border --exclude-titlebar button3 focus

With this PR the 'layout toggle' command can be passed any
combination of valid layout keywords as arguments. They will
be activated one after another each time you issue the command,
advancing from left to right always selecting the layout after
the currently active layout or the leftmost layout if the active
layout is not in the argument list.
This PR also incorporates the feature request from #2476.
With commit d58dbc3 we started ignoring Expose events in a sequence
except for the last one. Since we only copied the affected part of
the window in the Expose event handler, this caused incorrectly
rendered window decorations.
Instead of reverting to the old behavior, we now copy the entire window
content on this single, last event with the following rationale:
- It's cheaper to copy a larger chunk once than multiple smaller
chunks doing one server roundtrip each.
- That's how we do it when rendering out decoration on decoration
changes as well.
fixes#2683
This event is triggered when the connection to the ipc is about to
shutdown because of a user action such as with a `restart` or `exit`
command. The `change` field indicates why the ipc is shutting down. It
can be either "restart" or "exit".
fixes#2318
Previously rendering marks and the title were skipped if the title is empty. With marks
this is obviously wrong, with the title it is also wrong because title_format might be
set.
Doing a hard exit() is a rather harsh action for something i3 can handle
perfectly fine and is only meant to be a check to make debugging easier
for users in certain situations.
Thanks to @psychon for pointing this out during the review of PR #2624.
This commit extends this change to all other occurences of Expose events
within i3.
While defining the same mode usually wouldn't hurt and, in fact, the old behavior
allows to split the definition of a binding mode into several blocks, this
can lead to user errors where they accidentally define a mode twice and don't understand
why the mode behaves a certain way (this has been observed in real life :-)).
There's no good usecase for splitting a single binding mode into multiple blocks, thus
the new behavior is better.
fixes#2615
This commit is a rewrite of the popup dialogs used when i3 crashes. We now
use our draw_util suite and both properly react to EXPOSE events and clean
up the windows when the handler exits.
As a side-effect, this fixes#2422
This commit introduces proper support for the minimum size on floating
windows by ensuring that it is respected during mapping, later changes as
well as resizes.
Furthermore, this commit fixes minor issues with how the hints are handled

This comes with the intentionally undocumented --disable-randr15 command

need to use the flag and everything would just keep working, but it’s
better to be safe than sorry.

Fix the issue #2421 (https://github.com/i3/i3/issues/2421).
floating_enable() invokes tree_close_internal() to free con->parent.
After con->parent is freed in tree_close_internal() but before con->parent is reassigned by the caller, con->parent may be dereferenced and causes i3 crash.
The backtrace below is an example.
The already-freed pointer is dereferenced again through the pointer "focused" in x_push_changes().
Reassign con->parent before calling tree_close_internal() to fix this use-after-free bug.

Including config.h is necessary to get e.g. the _GNU_SOURCE define and
any other definitions that autoconf declares. Hence, config.h needs to
be included as the first header in each file.
This is done either via:
1. Including "common.h" (i3bar)
2. Including "libi3.h"
3. Including "all.h" (i3)
4. Including <config.h> directly
Also remove now-unused I3__FILE__, add copyright/license statement
where missing and switch include/all.h to #pragma once.
This commit probably comes as a surprise to some, given that one of i3’s
explicitly stated goals used to be “Do not use programs such as
autoconf/automake for configuration and creating unreadable/broken makefiles”.
I phrased this goal over 7 years ago, based largely on a grudge that I
inherited, which — as I’ve realized in the meantime — was largely held against
FOSS in general, and not actually nuanced criticism of autotools.
In the meantime, I have come to realize that the knee-jerk reaction of “I could
do this better!” (i.e. writing our own build system in this particular case) is
usually misguided, and nowadays I strongly suggest trying hard to fix the
existing system for the benefit of all existing and future users.
Further, I recently got to experience the other side of the coin, as I packaged
a new version of FreeRADIUS for Debian, which at the time of writing used
autoconf in combination with boilermake, a custom make-based build system that
only FreeRADIUS uses. Understanding the build system enough to fix issues and
enable parallel compilation took me an entire day. That time is time which
potentially every downstream maintainer needs to invest, and the resulting
knowledge cannot be applied to any other project.
Hence, I believe it’s a good idea switch i3 to autotools. Yes, it might be that
particular features were easier to implement/understand in our custom
Makefiles, and there might be individuals who have an easier time reading
through our custom Makefiles than learning autotools. All of these
considerations are outweighed by the benefits we get from using the same build
system as literally thousands of other FOSS software packages.
Aside from these somewhat philosophical considerations, there’s also practical
improvements which this change brings us. See the “changes” section below.
┌──────────────────────────────────────────────────────────────────────────────┐
│ new workflow │
└──────────────────────────────────────────────────────────────────────────────┘
You can now build i3 like you build any other software package which uses
autotools. Here’s a memory refresher:
autoreconf -fi
mkdir -p build && cd build
../configure
make -j8
(The autoreconf -fi step is unnecessary if you are building from a release
tarball, but shouldn’t hurt either.)
┌──────────────────────────────────────────────────────────────────────────────┐
│ recommended reading │
└──────────────────────────────────────────────────────────────────────────────┘
I very much recommend reading “A Practitioner's Guide to GNU Autoconf,
Automake, and Libtool” by John Calcote (https://www.nostarch.com/autotools.htm).
That book is from 2010 and, AFAICT, is the most up to date comprehensive
description of autotools. Do not read older documentation. In particular, if a
document you’re reading mentions configure.in (deprecated filename) or
recursive make (now considered harmful), it’s likely outdated.
┌──────────────────────────────────────────────────────────────────────────────┐
│ changes │
└──────────────────────────────────────────────────────────────────────────────┘
This commit implements the following new functionality/changes in behavior:
• We use the AX_ENABLE_BUILDDIR macro to enforce builds happening in a separate
directory. This is a prerequisite for the AX_EXTEND_SRCDIR macro and building
in a separate directory is common practice anyway. In case this causes any
trouble when packaging i3 for your distribution, please let me know.
• “make check” runs the i3 testsuite.
You can still use ./testcases/complete-run.pl to get the interactive progress
output.
• “make distcheck” (runs testsuite on “make dist” result, tiny bit quicker
feedback cycle than waiting for the travis build to catch the issue).
• “make uninstall” (occasionally requested by users who compile from source)
• “make” will build manpages/docs by default if the tools are installed.
Conversely, manpages/docs are not tried to be built for users who don’t want
to install all these dependencies to get started hacking on i3.
• non-release builds will enable address sanitizer by default. Use the
--disable-sanitizers configure option to turn off all sanitizers, and see
--help for available sanitizers.
• Support for pre-compiled headers (PCH) has been dropped for now in the
interest of simplicitly. Maybe we can re-add it later.
• coverage reports are now generated using “make check-code-coverage”, which
requires specifying --enable-code-coverage when calling configure.
┌──────────────────────────────────────────────────────────────────────────────┐
│ build system feature parity/testing │
└──────────────────────────────────────────────────────────────────────────────┘
In addition to what’s described above, I tested the following features:
• “make install” installs the same files (plus documentation and manpages)
cd i3-old && make install PREFIX=/tmp/inst/old
cd i3-new && ./configure --prefix=/tmp/inst/new
cd /tmp/inst
(cd old && for f in $(find); do [ -e "../new/$f" ] || echo "$f missing"; done)
• make dist generates a tarball which includes the same files
cd i3-old && make dist
cd i3-new/x86_64-pc-linux-gnu && make dist
colordiff -u <(tar tf i3-old/i3-4.12.tar.bz2 | sort) \
<(tar tf i3-new/x86_64-pc-linux-gnu/i3-4.12.tar.gz | sort)
There are some expected differences:
• Some files have been renamed (e.g. the new etc/ and share/ subdirectories)
• Some files will now be generated at build-time, so only their corresponding
.in file is shipped (e.g. testcases/complete-run.pl)
• The generated parser files are shipped in the dist tarball (they only
depend on the parser-specs/* files, not on the target system)
• autotools infrastructure is shipped (e.g. “configure”, “missing”, etc.)
• DLOG and ELOG statements still produce the same file name in logfiles
• Listing source code in gdb still works.
• gdb backtraces contain the i3-<version> path component
• release.sh still works
• version embedding
1. git checkout shows “4.12-136-gf720023 (2016-10-10, branch "autotools")”
2. tarball of a git version shows “4.12-non-git”
3. release tarball shows 4.13
• debug mode is enabled by default for non-release builds
• enabling verbose builds via V=1
┌──────────────────────────────────────────────────────────────────────────────┐
│ speed │
└──────────────────────────────────────────────────────────────────────────────┘
There is no noticeable difference in compilation speed itself (of binaries,
documentation and manpages):
i3-old $ time make all docs mans -j8
make all docs mans -j8 28.92s user 2.15s system 640% cpu 4.852 total
i3-new $ time make -j8
make -j8 27.08s user 1.92s system 620% cpu 4.669 total
In terms of one-time costs:
configuring the build system (../configure) takes about 2.7s on my machine,
generating the build system (autoreconf -fi) takes about 3.1s on my machine.

All files in m4/ have been copied from the autoconf-archive package in version

This commit has been tested with autoconf 2.69 and automake 1.15.
The idea was to ensure the symbol would always be present. For that, we need
__attribute__((used)), not __attribute__((unused)). Further, ensure the
variable has static storage, as the used attribute only applies to variables
with static storage. See also http://stackoverflow.com/a/29545417/712014
We strive to avoid conditional compilation in i3 as much as possible.
cairo and pangocairo have been around long enough in the versions that
we need that it’s time to unconditionally depend on them.
Also update DEPENDS with the last-known-good-versions while at it.
We call scratchpad_show() on _NET_ACTIVE_WINDOW requests if the request
came from a pager. This is consistent with the i3 »focus« command because
we assume the user requested to see the window, so we do the only
sensible thing.
fixes#2455
When receiving an ENTER_NOTIFY event on a dock client we returned as to not
focus the dock client (cf. #321 and #323). However, we still need to check
for crossing output boundaries and if that happened focus the new output.
Otherwise it can happen that the cursor is on a different output than the
focused output. When opening a window, this would open it on the old output
and then warp the mouse there. This effect will be even worse if the window
is immediately moved with 'move position mouse' as the window will end up
in its correct position on the new output and the cursor warped to the old
output.
relates to #2081
This commit correctly handles colormaps by
* Using the static default colormap we determine on startup if the
con has the corresponding depth. This avoids creating pointless
colormaps.
* Not freeing the default colormap to not have stray colormaps on
containers. This fixes an issue with certain programs such as xwd.
* Creating a custom colormap when necessary and freeing it when the
container is killed.
fixes#2435
Before this commit, i3 only compared the user-specified modifiers and
incorrectly ignored the resolved modifiers (such as the numlock
fallback).
While at it, also fix the testcase which treated numlock as a momentary
modifier, whereas it really is a latched modifier.
fixes#2418
Previously, we always discarded the NumLock bit when looking up key
bindings for key press events, and we always grabbed every keycode with
and without the NumLock modifier.
With this commit, the NumLock bit is no longer discarded: since the
previous commit 3bd5e6e5c8 we can
correctly look up key bindings with/without the NumLock bit, as both
variants are stored in |keycodes_head|.
Further, before adding the NumLock fallback (resulting in grabbing the
keycode with the NumLock modifier), we now check whether the key has the
same meaning when NumLock is enabled. This correctly distinguishes the
KP_End vs. KP_1 case, i.e. one can now use the following key bindings:
# No longer accidentally triggered when pressing KP_1.
bindsym KP_End nop KP_End
# Properly distinguished now:
bindsym KP_End nop KP_End
bindsym Mod2+KP_1 nop KP_1

since OpenBSD pthread does not support pthread_condattr_setpshared().
This patch could also stay in the OpenBSD ports tree or depend on a
configure test macro rather than defined __OpenBSD__.
Prior to this commit a binding specifying only --whole-window would
trigger even when clicking on the window border. However, this should
only happen if --border is specified.
fixes#2348
Use case:
* When managing multiple terminals in a workspace, the borders makes it easier
to know where the focus is, but when there is only one it's obvious where the
focus is.
* When there's only a web browser for example, the borders are actually counter-
productive since it makes clicking a side scrollbar or a tab a bit harder (if I
smash my cursor to the side or the top of the workspace, I have to move it in
the other direction by just a few pixels to be able to grab it)
Behaviour:
* No borders when there's a single window in a workspace
* Borders when there are multiple windows in a workspace
fixes#2188
This patch introduces a new 'set_from_resource' config directive which
allows defining a variable by retrieving its value from the X resource
database. This avoids having to configure a color scheme in multiple
files. The directive takes an additional fallback value which is used
in case the resource cannot be found or during config validation where
no X connection is available.
Furthermore, this patch includes the following changes:
- If the same variable is defined twice, we now properly overwrite the
value of the assignment rather than inserting two variable definitions
with the same key.
- We now depend on xcb-util-xrm to query the resource.
- Increase the buffer size for variable / resource assignments.
fixes#2130
If an output is disabled during a restart, for example because a binding
such as
bindsym $mod+Shift+r exec "xrandr --auto", restart
is used, it can happen that we first write the layout to disk and only
then receive the RandR change events. This leads to a situation where
the restored tree will contain these outputs, but the restarted i3
process will not receive the RandR events, thus the internal output in i3
is marked disabled.
This patch finds these cases after a restart and force-disables the
affected outputs.
fixes#2326
In most cases this won't make a difference, but consider the following
scenario:
* Some application acquires input focus on its own (which the window manager
is not involved in, so it will "always" work).
* Before the FocusIn / FocusOut events are processed by i3, the
workflow to push X changes is run, resulting in xcb_set_input_focus()
being called.
Using XCB_CURRENT_TIME, this means i3 will "win" and override the focus,
even though it simply wasn't aware (yet) that focus had already been taken
over by someone else. When processing the FocusIn / FocusOut events, i3
assumes that the focus is already set which results in a broken focus
state as i3 assumes some container has the input focus when it doesn't.
With the new behavior, i3's attempt to set the input focus will fail if
the FocusIn / FocusOut events have not yet processed. Once they are processed,
the focus state will be automatically corrected.
fixes#2322
This code has been neutralized for many years now and served no purpose
other than cluttering up the code. We obviously don't need it and it's
out of date anyway.
If there's ever any reason to restore (parts of) it, we have git for
that. But we don't need to keep commented out code around.
This commit removes the title indentation in certain nested container
situations. The behavior was considered broken as it didn't seem to
make sense and it was unclear why this was introduced.
Given that nobody on i3-discuss@ complained about removing this logic
within two weeks, we are now removing it to make the title rendering
code a little less complex.
fixes#2247
Since we don't actually stop drawing a title (or marks) with the
distance of the border width on the right side, but instead with
a hard-coded two pixel distance, we can only redraw that much of
the border without potentiall cutting off text.

Use `uintptr_t` to cast the con id to int instead of `long int`. This
type is guaranteed to hold the pointer as an int regardless of platform.
fixes#2283
Previously we counted the number of (direct) children of the workspace to
decide whether no_focus should be applied or not. However, this doesn't
work correctly if there's a single container with multiple windows on the
workspace.
This patch correctly counts all windows on the workspace.
fixes#2292
This is a followup to #2049. While we had fixed that bug by only grabbing
buttons 4 and 5 if there is a whole-window binding for that button, this
did not consider buttons higher than 5 as found on many mice.
Therefore, we now ditch the special handling for scrollwheel buttons and
instead do the same for all buttons higher than 3.
fixes#2271
With this change, multi-monitor presentations (e.g. as implemented by
LibreOffice Impress) work out of the box. Previously, one had to move
the presentation windows to the right outputs oneself.
If a user reloads the config while in some binding mode, the binding mode
will revert to the default, but no event will ever be fired, causing a
broken i3bar mode display.
This patch explicitly reverts to the default binding mode before reloading
the config. We reload rather than switch to the binding mode after having
reloaded the config because there's no guarantee that mode will even still
exist.
fixes#2228
This patch correctly determines the previously focused workspace on the
target output when moving a workspace to another output. Before, we used
nodes_head for this, which will not actually return the previously focused
workspace, but just the first workspace on that output. Hence, we now use
focus_head instead.
This bug was introduced all the way back in 1e143fea when the feature of
moving workspaces to another output was first implemented.
fixes#2229
This patch introduces a proprietary atom I3_FLOATING_WINDOW which will be
set and maintained for floating windows and removed on tiling containers.
This allows users to select on this atom, e.g., in their compositor
configuration or in utility scripts (without using the IPC).
fixes#2223
Manually updating a magic number doesn’t work in the long run.
With this change, the number of atoms contained in
include/atoms_NET_SUPPORTED.xmacro is used.
fixes#2230
This is essentially a revert of daf00a9 which introduced a mechanism
to float workspace containers by wrapping all children into a new
container and floating it.
This caused a bug and there's no good reason (anymore) to allow doing
this in the first place as we don't support floating nested containers.
fixes#2166
This allows "modifier none" (and "modifier off") for the bar config
in order to disable the modifier key altogether. This is useful
for users who use a different approach to hiding / showing the bar,
e.g., a custom keybind that involved multiple keys or scripts.
fixes#2208
Until now, only the config directive for borders (new_window,
new_float) respected the DPI setting (using logical_px). This
patch makes sure we also do so for runtime "border" commands.
fixes#2202
We now build a docker base container based on debian sid (where the very
latest packages are available). That base container is updated once a
month, or whenever travis-build.Dockerfile or debian/control change, but
re-used for subsequent travis runs. While the initial build might take
up to 15 minutes, subsequent builds typically run in a minute or two.
All the different steps that we run on travis are now factored into
separate scripts in the travis/ directory.
Switching to docker should also help with issue #2174.
Ignoring the focus leads to a broken focus if the pointer is, e.g.,
over i3bar at the point in time the window is moved by the client
message. It also causes i3bar's workspace display to break.
Thanks to GermainZ for reporting.
We don't actually need to grab the buttons to fix#2097, but doing so
will cause a freeze due to unreleased events.
We partially revert 6f12f02 which avoids the freeze, but doesn't break
functionality.

We already claim _NET_WM_DESKTOP support in _NET_SUPPORTED since around 2009,
but haven't actually done anything with it. However, especially pagers like
gnome-panel rely on this property to be updated and many tools, like GTK, want
to use the corresponding client messages to make a window sticky, move it
around etc.
This patch implements full support according to the EWMH spec. This means:
* We set the property on all windows when managing it.
* We keep the property updated on all windows at all times.
* We read and respect the property upon managing a window if it was set before
mapping the window.
* We react to client messages for it.
* We remove the property on withdrawn windows.
Note that the special value 0xFFFFFFFF, according to the spec, means that the
window shall be shown on all workspaces. We do this by making it sticky and
float it. This shows it on all workspaces at least on the output it is on.
Furthermore, the spec gives us the freedom to ignore _NET_WM_DESKTOP when
managing a window if we have good reason to. In our case, we give window
swallowing a higher priority since the user would likely expect that and we
want to keep placeholder windows only around for as long as we have to.
However, we do prioritize this property over, for example, startup
notifications.

pledges for i3:
"stdio rpath unix" for talking to the i3 socket usually in /tmp
"proc exec" for executing programs
"wpath cpath" are needed for the restart-in-place functionality
To make this work, @semarie pointed out that it is sufficient to ensure
that we get physical_mem_bytes only once, namely in init_logging().
pledges for i3-msg:
"stdio rpath unix" are needed for talking to the i3-socket
pledges for i3-nagbar
"rpath getpw" to find the home directory
"wpath cpath" to write the script
"proc exec" to execute the script
This disables the default leak-check-on-exit behavior which reports a
bunch of leaks that are only leaks while exiting, at which point they
don’t matter, because the operating system will clean up the memory our
process used.
