When fluxbox comes up some of it's drawables span a 1x1 area. Subtracting from
such small numbers bigger ones always lead to massive problems when 'unsigned
int' are involved:
'button_width' is an unsigned int of '1' (this might be caused by another
issue or on purpose, anyway), subtracting -10 or any other number should
result in something < 0 when in reality an integer underflow happen: max_width
is now MAX_INT-something big. This makes fluxbox crash under certain
circumstances.
This fixes bug #1116.

* Correctly build data files when operate outside of the $(srcdir)
* Actually install data files
* Use pkg-config to detect X11, works better on MacOSX. We used pkg-config
already anyway, double checking for X11 does not yield better results.
* Replace EXEEXT in some files while before installing them

xxx_LDFLAGS place the libraries like '-lX11' or '-lXft' at the beginning of
the linker command. Some systems were not able to handle the situation and
this lead to a lot of unresolved symbols. Reading the documentation of
automake:
... you can use LDADD to do so. This variable is used to specify
additional objects or libraries to link with; it is inappropriate for
specifying specific linker flags, you should use AM_LDFLAGS for this
purpose.
In addition we link against -lm in order to satisfy symbols refering to 'cos'
and 'sin'.

POSIX states that 'd_name' in 'struct dirent' is char[], so it cannot be NULL.
This will result in the compiler complainting about an expression which always
evaluates to true ... for this compiler (clang). But in some implementations
'd_name' is a 'char*' that's why it's better to keep the check for possible
NULL.

OSDWindow::resize(const FbTk::BiDiString&) shadowed FbWindow::resize(x, y). To
fix this I renamed the function to OSDWindow::resizeForText() to make the
intention clear.

As correctly pointed out by 'Nable80': "%llx" does not create the 0x prefix
for the hex-string. In addition to that: snprintf() adds a terminating \0.

Again: Compiler happy, we are happy.

While running code analysis tools this issue popped up. As it is written it is
clearly a NOP, but the reason for why it is written that way remains unknown.
I suspect that it was a textfragment introduced by some repeat-function of the
used editor (think '.' in VIM). The code was introduced by commit a932a7a801
and looked like this in the original form:
if(!XQueryTree(FbTk::App::instance()->display(), window().window(),
&root_return, &parent_return,
&children_return, &nchildren_return))
parent_return=parent_return;//return;
Look at the outcommented return statement. I decided to return from that
function instead of the NOP.

Clang and Gcc-4.9 complaint about some unused variables here
and there. And who are we to not make a compiler happy :)

this commit implements feature-request #317: "Add support for GTK dockapps.":
"Back in 2010, WindowMaker implemented a system where windows with WM_CLASS
res_class = DockApp would be treated as if they had initial_state =
WithdrawnState, since GTK refuses to allow this."

File name expansion is done internally by the Slit::loadClientList, so there
is no need to duplicate the code.

kudos to Arkadiusz Bokowy (this commit is a slightly changed version
of a patch sent to the devel-ml): when retrieving the '.res_name' of
a XClassHint we should check '.res_name' and not '.res_class'.
the other changes only reduce the code.

handing over the dimensions of a WinClient client must not contain properties
of the FbWinFrame, otherwise they get added twice in
FbWinFrame::moveResizeForClient() and thus result in a resizes when no resize
is wanted.
other changes: it's easier for me to detect the nth bit when the value looks
like (1 << 8) instead of 0x0100 (for the 8th bit). that is why i changed
0x0100, 0x0200 etc. in the nearby code.

the -1 in the FbTk::FbTimer::remainingNext() function was pointless in the
first place anyway: reducing the timeout by just 1 microsecond improves
nothing (in this case). if the timer triggers exactly at a full unit (second)
then it's correct to wait for the full next unit.
|

the lag / skipping of the clock was not caused by faulty timer code
on fluxbox's side but by the behavior and inner workings of time().
since this is fixed now (913244789f) we can now rollback ec7fe513c8
and detect strftime-formats which need intervals of seconds or minutes.
minor: the small change to FbTk::Timer::setTimeout() reduces one
start() / stop() cycle for a running timer.

from time to time (...) time() might be off to gettimeofday() by a
second. the reason for this is that time() is usually implemented
by just returning the field 'second' of the struct that represents
the clock inside the kernel. gettimeofday() on the other hand also
takes the 'fraction' field (mostly 'nanoseconds') into account and
thus is closer to the current time than time().
the result of using time() was a perceived 'lag', sometimes the
clocktool even skipped a second. by using FbTk::FbTime()::system()
instead fixes the issue.

xmodmap (and other tools) trigger MappingNotify events. a single xmodmap
expression such as "keycode comma = comma semicolon" might trigger 4 or 5
MappingNotify events. loading the keys file on each of them is quite
unefficient.
fluxbox now uses a (250ms) timer which is reset upon further events.

there is problem that x/y ended with unsigned int value due to
width()/height() and negative result of division ended up being big
it causes Focus to move window due to screen boundary checks
fixes annoying behaviour of window moving few pixels with
Mod4 KP_8 :MacroCmd {ResizeTo 100% 50%} {MoveTo 0 0 Top} {Raise} {Focus}

This commit fixes primarily a race condition that occurs when xinit(1) shuts
down: by not acting properly fluxbox gets caught in an infinite loop. It
caused bug #1100.
xinit(1) sends a SIGHUP signal to all processes. fluxbox tries to shutdown
itself properly by shutting down workspaces and screens. While doing that, the
Xserver might be gone already. Additionally, fluxbox used to restart() itself
on SIGHUP, which is clearly not the right thing to do when xinit(1) is about
to end the session.
So, fluxbox does this:
* handling SIGHUP now shuts down fluxbox without clearing workspaces and
screens.
* A 2 second alarm() is triggered in Fluxbox::shutdown() as a last resort
* XSetIOErrorHandler() is used to recognize the disconnect from the xserver.
* SIGUSR1 is for restarting fluxbox, SIGUSR2 for reloading the config
* FbTk/SignalHandler.cc/hh is gone; this unused abstraction served currently
no real purpose. Signal handling is now done in main.cc
* Unrelated to the issue itself src/main.cc was trimmed down quite a bit and
the code (responsible for handling the command line interface) was moved to
src/cli*

* Fix integer wrap around for some situations (resulting in a very wide
window):
w = max_width - x_offs - (*closest)->widthOffset()
If the given window is on the right most display and thus 'x_offs' is
bigger than 'max_width' (half of the display width), the resulting 'w' wraps
around and becomes very large.
* Place a single window via ArrangeWindowsStack* as well
* Some minor code styling / reordering along the way

Do not Ungrab the keyboard for a KeyPress event, this causes us to lose the
KeyRelease event which is needed to ungrab the keyboard after the event
happened.

std::bind2nd() has problems with the existing call because it uses the
argument type passed to std::equal_to() in std::binder2nd()'s constructor,
but WinClient* does not have the const specifier that `client' does.
The call works fine with libstdc++ because of the way it implements
std::bind2nd(), but fails with libc++ and possibly with other STL
implementations as well.

usually $HOME is set when fluxbox runs. in some rare scenarios (eg., fuzzying
binaries to detect bugs) one could launch fluxbox by using 'env -i' and thus
eliminating $HOME from the environment. to prevent crashes fluxbox uses now
'getpwuid()' when $HOME is not set to detect the home folder.

Detecting very long window titles is done via FbTk::TextUtils::doAlignment().
Instead of removing one char from the title at a time to see if it fits into a
given 'max_width', we now use a binary-search like approach to get faster to
the right value. This massively improves the speed for windows with
(arbitrary) long window titles (see bug #1090, javascript
document.title = new Array(4999).join(".");
leads to massive waiting for fluxbox to detect that this window has a very
long title).
In addition to that Xft returns 'wrapped' shorts ('integer overflows') for
long texts: XGlpyhInfo.xOff is declared as signed short, it's able to hold
~32k pixels. A monospace font with font-size 10 produces an integer
overflow after 3276 chars / glyphs, thus rendering the check
if (text_width < max_width) { /* ... */ }
pointless and leading rendering the whole title. By calculating some kind of
upper limit for a pseudo-wide glyph ("WW") and strictly cutting off the input
string at that limit prevents this issue.

This rather large change will attempts to make 'make' to work better.
See excellent paper 'Recursive Make Considered Harmful' by Peter Miller
for further explanation why several make files is worse than one for
whole project.
Note. The tests are build with 'make check' rather than defining TEST.

This commit alters XRANDR (X Resize And Rotate) extension dependency,
which is expected to have at least version 1.4. Earlier old versions of
xrandr were supported, at least to some extent.

The earlier _GNU_SOURCE definitions possibly did not take effect
everywhere where it was intended.
|

Do not try to be too smart which compilations need config.h, as most of
them will simply because of the config.h has information about system
capabilities.
