As pointed by Coverity, the file descriptor used in 'dup' to become the
child process's STDIN is leaked, because it will not be used anymore, so we
close it after the dup.
Similarly, the file descriptors that represent the other ends of the pipe
for each process are useless, so let's close them too to keep a reasonable
number of opened file descriptors over time.

moved to a dedicated function, which have been moved to the same location
as the function for communicating with the helper.

There was a probable bug when reading settings, because the function used
was 'getInt' which would try to store the result in a 'char'. As it would
be probably easier for user to have the value directly in pixels, the
storage is now done in an int so there won't be problem anymore.
Changed the behaviour of the constant APERCU_BORDER, which would be assumed
to be the size of the border in pixel, but in previous code it was actually
the sum of the two border (1 on each side). All maths have been changed to
have it as a single border width.
Took opportunity to group variable assignation for titleHeight and
shortenTitle in a single place, because it is not convenient to have them
spread around (one value in the beginning and others later in the code) and
using default values prevents some checks that modern compiler can do to
help produce safer code.

As pointed by Coverity, the return value is saved into a variable, but this
value is never used. As the variable is re-used afterwards, this
assignation could mislead on what is done, so for code maintainability the
value is just ignored.

As pointed by Coverity, the function GetShortcutKey was allocating memory
for temporary operation, and did not free it in the end.
Because it participates in memory fragmentation and it is not really
efficient, this patch removes the allocation and uses a local storage on
the stack, and replaces wstrappend in favour of a fast string build.

A type conversion applied to a function when used as a pointer is dangerous
because the compiler may not be able to make sure arguments will be
compatible across architectures, so it can crash the application.
This is replaced by a function prototype matching exactly what is expected
for the callback, and have the type conversion on the argument done inside
the function so the compiler have complete liberty to generate any code
needed to handle it safely.

Revert patches that moved variables from WMScreen to global level
because this broke X displays with multiple independent screens and
caused dock and clip icons to become mixed up. When managing multiple

commit restores that by reverting mainly the commits listed below (and
those that are invalidated by reverting these) and fixing up later
commits to apply after the revert.

Previously, the whitespace in WindowMaker was inconsistent, with some
indentation using spaces and some using tabs, and a mixture of tabs and spaces
used to align comments at the ends of lines. As a result, patches that touched
this file would often result in warnings from checkpatch.pl.
This patch fixes this so that indentation uses tabs and all other alignment uses
spaces.

You can now configure the behavior when dragging a maximized window by setting
DragMaximizedWindow in ~/GNUstep/Defaults/WindowMaker. The options are:
- Move: Move the window and retain its maximized status and geometry (the
current behavior and the default).
- RestoreGeometry: Move the window and unmaximize it, restoring its original
geometry.
- Unmaximize: Move the window and unmaximize it, retaining its maximized
geometry.
- NoMove: Don't move the window.

This patch adds the ability to completely unmaximize, i.e., clear the maximized
flag and return to the original geometry, a maximized window that is moved.
This behavior mirrors that of other common desktop enviroments, e.g., GNOME,
Unity, and Windows.
To enable this feature, set "UnmaximizeOnMove = YES" in
~/GNUstep/Defaults/WindowMaker.

If a user moves a window which is currently maximized, the current behavior is
to keep the window geometry and maximized status unchanged. This can lead to
peculiar behavior. For example, suppose a user maximizes a window to the
right half of the screen (either through the window menu, keyboard shortcut, or
new snapping feature), then moves it, and then attempts maximize it to the
right half of the screen again. Instead of the expected result, the window is
unmaximized and returned to its original geometry.
This patch changes the behavior by clearing the maximization flag when a
maximized window is moved. Then, when a window is maximized and then moved, it
can be maximized again without issues.

Note that window snapping is automatically disabled if DontLinkWorkspaces =
"NO", as this feature also involves dragging a window to one side of the

This patch is adding the _NET_WORKAREA property
which according to EWMH spec MUST be implemented.
Some application like rdesktop or nautilus are using
it, that's maybe why you encountered some errors like these:
** (nautilus:6457): WARNING **: Can not get _NET_WORKAREA
** (nautilus:6457): WARNING **: Can not determine workarea, guessing at layout
For now, the property is only updated when a workarea is created or destroyed.
This patch is updating the coding style based on checkpatch output
and as suggested by Rodolfo it also inverts the condition test
in getAnimationGeometry fct to return earlier when possible.
This patch is fixing the shortcut label used in window menu.
As now when a 'control' shortcut was used, the label displayed
was 'bug' cause GetShortcutString fct which is calling wXModifierFromKey
fct was waiting for a 'Control' static string not the default one
set to 'Ctrl' string.
This patch is fixing the RenderBadPicture X errors on deiconifying
window using double-click.
Background:
I also experienced this issue these days, after checking it was not
introduce with latest apercu feature I decided to dig into it.
As far as I saw in the archive it was first reported by Rodolfo in June 2012.
Each time a window is deiconify using double-click, the error below
is reported in the session error log:
wmaker(catchXError(startup.c:177)): warning: internal X error:
RenderBadPicture (invalid Picture parameter)
Request code: 152
Request minor code: 7
Resource ID: 0x6000a4
Error serial: 9269
So I decided to track when the issue is happening,
from src/action.c wDeiconifyWindow then in src/icon.c wIconDestroy
then in src/wcore.c wCoreDestroy.
At that stage, all the structures I checked are cleaned up properly
during the icon destroy process.
So I also checked when the issue is generated, I ended in
wrlib/xutil.c RCreateXImage (in the share memory extension code)
XSync(context->dpy, False);
oldErrorHandler = XSetErrorHandler(errorHandler);
XShmAttach(context->dpy, &rximg->info);
XSync(context->dpy, False);
XSetErrorHandler(oldErrorHandler);
At this point I was quite lost, cause it means the error could
have been in the server error queue already.
Facts, seems the issue is appearing only on double-clicking the miniwindow,
but not when "Deminiaturize" is clicked from the right-click contextual menu.
I also checked the code from winmenu.c when the action MC_MINIATURIZE
is selected from execMenuCommand fct, but it was just calling
wDeiconifyWindow function. Hum.
So, after one full day of thought I tested to just change the focus before
double-clicking the miniwindow, and bingo it works.
That means when the icon is destroyed the X server still has a reference
on it that's generating the issue.
Since the resolution of the Retina display tends to make everything small,
the default apercu preview size (twice the icon size) couldn't be used to
distinguish the window contents without tiring too much my eyes.
Therefore, let's make the apercu size a configurable option. You can set
it through the ApercuSize variable with
$ wdwrite WindowMaker ApercuSize 4
in multiples of the icon size (in this case the apercu size will be four
times the icon size).
The default size remains 2 (twice the icon size).
This patch is adding miniwindow apercu when the mouse
is over the miniwindows.
To enable it you have to run WPref, in Miscellaneous Ergonomic
Preferences, check miniwindow apercus.
Then, you will be able to see a screenshot of the app when the mouse
is over the miniwindow.
This patch is setting the app logo max size to 128 as what can
be found in the rest of the code, so the logo is not restricted
anymore to the icon size defined by WPrefs.
The goal is to solve the resize issue that appears when the logo
is used in Info and Exit panel.
This patch is fixing compilation issue:
moveres.c:1801:65: warning: unused parameter 'dx' [-Wunused-parameter]
by removing variable 'dx' from getResizeDirection function.
This patch is removing the experimental status of
drag-nd-drop support on the dock and adding an option
to disable the feature from the configure step.
This patch is ensuring that the data dropped is a file format URI
and converting it as stated by XDND specs.
It solves:
*crash in my env when arbitrary stuff is dropped
*correct handling of non ascii chars
