This reverts commit 2d33c20231 and
reapplies various patches for memory leaks.
The reason for the revert was a bug for a maximum duration interval
which caused sleep_for() to cause unpredictable behavior.
In the previous fix for a passed max duration, the assumption was made
that at maximum one second will pass between the duration assignment and
the std::condition_variable::sleep_for() call.
This implementation makes the behavior more predictable by using
sleep_until() instead to emulate the sleep_for() behavior.
The standard library has the implicit requirement that for
std::condition_variable::sleep_for() the duration must not cause an
overflow if added to the current time.
This commit will reduce the duration accordingly to fit into the
duration type.
This keeps the function consistent with sleep_until() and sleep_for()
which both can be interrupted.
This is relevant to allow an update via a "signal" without an "interval"
in a custom module.
The module provides the three system load averages. This is an
improvement compared what you can do with the cpu module: cpu
only provides the one minute sample and the state of the cpu module is
derived from the cpu usage which messes up the formating of the load
average. Also, at least on modern Linux systems, the load of a system
takes much more than the cpu utilization into account and it should
therefore live in a separate module.
summary:
-------
This commit adds xdg-desktop-portal support to waybar. If a portal
supporting `org.freedesktop.portal.Settings` exists, then it will be
queried for the current colorscheme. This colorscheme will then be used
to prefer a `style-light.css` or `style-dark.css` over the basic
`style.css`.
technical details:
-----------------
Appearance is provided by several libraries, such as libhandy (mobile)
and libadwaita. However, waybar links to neither of these libraries. As
the amount of code required to communicate with xdg-desktop portal as a
client is rather minimal, I believe doing so is better than linking to
an additional library.
The Gio library for communicating with dbus is rather messy, Instead of
the `Portal` class containing a `Gio::Dbus::Proxy`, it extends it which
simplifies signal handling.
`Portal` then exposes its own signal, which can be listened to by waybar
to update CSS.
For a reference implementation, please see another one of my projects:
https://github.com/4e554c4c/darkman.nvim/blob/main/portal.go
test plan:
---------
If no desktop portal which provides `Settings` exists, then waybar
continues with the log line
```
[2023-09-06 14:14:37.754] [info] Unable to receive desktop appearance: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface “org.freedesktop.portal.Settings” on object at path /org/freedesktop/portal/desktop
```
Furthermore, if `style-light.css` or `style-dark.css` do not exist, then
`style.css` will still be searched for.
Waybar has been tested with both light and dark startup. E.g. if the
appearance is dark on startup the log lines
```
[2023-09-06 14:27:45.379] [info] Discovered appearance 'dark'
[2023-09-06 14:27:45.379] [debug] Try expanding: $XDG_CONFIG_HOME/waybar/style-dark.css
[2023-09-06 14:27:45.379] [debug] Found config file: $XDG_CONFIG_HOME/waybar/style-dark.css
[2023-09-06 14:27:45.379] [info] Using CSS file /home/pounce/.config/waybar/style-dark.css
```
will be observed.
If the color then changes to light during the operation of waybar, it
will change css files:
```
[2023-09-06 14:28:17.173] [info] Received new appearance 'dark'
[2023-09-06 14:28:17.173] [debug] Try expanding: $XDG_CONFIG_HOME/waybar/style-light.css
[2023-09-06 14:28:17.173] [debug] Found config file: $XDG_CONFIG_HOME/waybar/style-light.css
[2023-09-06 14:28:17.173] [info] Using CSS file /home/pounce/.config/waybar/style-light.css
```
Finally, tested resetting waybar and toggling style (works, and style is
only changed once).
fixes: Alexays/Waybar#1973
The segfaults were happening on GTK icon theme functions, which are
called via the C++ interface functions such as Gtk::IconTheme::has_icon.
There are multiple modules and threads using this functions on the default
icon theme by calling Gtk::IconTheme::get_default(), which returns the same
object for all callers, and was causing concurrent access to the same internal
data structures on the GTK lib. Even a seemingly read-only function such as
has_icon can cause writes due to the internal icon cache being updated.
To avoid this issues, a program wide global mutex must be used to ensure
a single thread is accessing the default icon theme instance.
This commit implements wrappers for the existing IconTheme function calls,
ensuring the global lock is held while calling the underling GTK functions.
This commit allows better handling of ordering and exclusion of the tags in Dynamics tags.
It also becomes possible to choose the separator between the tags.
Avoids a race where the pipe could be inherited by another process
spawning at about the same time. If the other process didn't exit
quickly (e.g. if it was a custom script that did its own looping), it
would keep the write end of the pipe open, and so reading from the pipe
to try to get the command's output would block.
This bug manifested as some custom modules randomly not appearing in the
bar, requiring a reload to fix. The custom script had run and exited,
but the pipe had been inherited by another process, and the thread that
updated the module's output was blocked trying to read from it.
some users (maybe only myself) may want to sort the task bar by app_id
which then places occurrences of the same task next to each other.

In order to fix the issue, the default node name is cached rather than
the default node id. This is due to ids being unstable. So now when the
object manager is installed (ie ready), the default node name is
retrieved and stored for later.
Now when the mixer changed signal is emitted, the id of the changed node
is used to get the node from the object manager. The nodes name is
grabbed off that node and compared against the default node name, if
they match the volume is updated. Some safeguarding has been added such
that if the node cannot be found off the object manager, it's ignored.
Additionally, the "changed" signal on the default nodes api is now
utilized to update the default node name if it has changed. This way if
the default node changes, the module will be updated with the correct
volume and node.nick.
This adds additional debug logging for helping diagnose wireplumber
issues.
This also adds the wireplumber man page entry to the main waybar
supported section.
Provides CSS classes empty, floating, tabbed, tiled, solo, stacked and
app_id.
Adds offscreen-css bool option (default false), only effective when
"all-outputs" is true. This adds styles on outputs without focused
node, according to its focused workspaces window situation.
Adds an "offscreen-css-text" string option (default empty), only
effective when "all-outputs" and "offscreen-style" are set. This
is shown as a text on outputs without a focused node.
Adds a "show-focused-workspace" bool option (default false) to indicate
the workspace name if the whole workspace is focused when nodes are
also present. If not set, empty text is shown, but css classes
according to nodes in the workspace are still applied.
Limitation:
When the top level layout changes, there is no sway event so the
module cannot react. Perhaps in the future recurring polling can
be added to go around this limitation.
1. Calendar. Weeks. Fix right paddings when first days of the week is
Monday
2. Fix small perfomrance penalty(avoid of defining parameter in the
month loop)
3. Small name convention for format string variables
1. Let's do code simplier
2. Week format using regexp. Needs when user provide additional
characters in format string and need to align week days according
3. Week format has got default formats: ":%U",":%V"
4. Week number is based on the first day of the week now. The output is
the same as of date library now.
5. Avoiding of unnecessary operations
