by using FbCommands::ExecureCmd() we run 'fluxbox-update_configs' in
the bacground while booting a new fluxbox instance already. 'system()'
waits until 'fluxbox-update_configs' is done and then gives the control
back to fluxbox.
before bringing up the first instance of Fluxbox we prepare the directory
and the files it needs. if the config version of exiting files is lower
than what we expect, we upgrade the config files. after that we bring
up Fluxbox.
the old way was problematic because setupConfigFiles() calls
'fluxbox-update_configs' which does its job in the background while
fluxbox continues to boot. 'fluxbox-update_configs' sends a USR2 signal
to the booting fluxbox (it might even be finished, no one knows) which
triggers 'load_rc()' which triggered 'setupConfigFiles()' again which
might trigger 'fluxbox-update_configs' again (on my machine
'fluxbox-update_configs' was called 3 times and left a pretty crippled
'keys' file when it was done).
bootstrapping before bringing up fluxbox resolves the issue. as a bonus:
no need to send USR2 to fluxbox to reload the config file because fluxbox
has not even tried to read it yet.
to quote from 'man putenv':
The string pointed to by string becomes part of the environment,
so altering the string changes the environment.
so, using putenv like
{
std::string foo("FOO=bar");
putenv(foo.c_str());
}
is wrong and leads to a potentially corrupted environment. valgrind
complaint correctly.
FbTk::App seems to be the appropriate place to hold '::seten()'
because it alters the environment of the application.
besides xpm. to get imlib2 support in fluxbox one has to
./configure --enable-imblib2
default is disabled. a fluxbox-binary that supports imlib2 will have
IMLIB2 in "fluxbox -info"-output
explanation to the changed files:
* xft.m4 -> acinclude.m4 + added ac_path_generic.m4
(from http://ac-archive.sourceforge.net/Miscellaneous/ac_path_generic.html)
* configure.in, Makefile.am, src/FbTk/Makefile.am changed to handle
imlib2-support
* Font.cc/hh Image.cc/hh App.cc fluxbox.cc consistent way of init for global
stuff for fonts and imagehandlers.
* rest of changes just add the imlib2-code, pretty straightforward
