Among the first steps to produce better i18n support is to test the created
translations adhoc without running "make install". To achieve this, fluxbox
now honors several environment variables:
- NLSPATH: fluxbox won't create the absolute path to the catalog and thus
catopen() is free to use NLSPATH as described in the manpage. Example
given: "/tmp/%N" will pick "/tmp/fluxbox.cat". %N refers to FLUXBOX_CATFILE.
- FLUXBOX_CATFILE: By setting FLUXBOX_CATFILE the users can make fluxbox to
use a different name for the catalog file. Default: "fluxbox.cat"
- FLUXBOX_CATDIR: Per default fluxbox tries to find FLUXBOX_CATFILE at several
places. Setting this environment variable allows to point fluxbox to a
different search path for the catalog files.
Then, fluxbox tries catopen() first without changing the deduced catalog file
name. After that it applies some heuristics to get a good catalog file name.

Move private stuff into FbTk/I18n.cc.
|
|
Note: I expect only modern compilers will hit the source of fluxbox. It
seems futile to guard stdlib headers while demanding <algorithm> etc. This
should trim down the noise in the source quite a bit.

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*

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.

|
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.
|

Added the option to remove the SystemTray tool completely from
fluxbox.

The changes made in b178bed60b5bd8b2c9ed0cbc67fd729ff3820589 used the wrong
variable to set the default state of '--enable-randr' in configure.in, that is fixed now. I
also removed '--enable-randr12': If support for the Xrandr-extension is
available at compile time we set HAVE_RANDR; if there is also support for
Xrandr-1.2 (or higher), we also set HAVE_RANDR1_2 automatically.
Other changes:
* cleaned out public interface of 'class Fluxbox'
* added 'RANDR' to output of 'fluxbox -info'
|
|
* reduced duplicated auto-code
* renamed '--enable-newwmspec' to '--enable-ewmh'
* don't compile 'Slit'-code when '--disable-slit'
* use AS_IF() in configure.in
* use AS_HELP_STRING() instead of obsolete AC_HELP_STRING in configure.in
* removed redundant calls to 'imlib2-config' to fill in $IMLIB2_CFLAGS
and $IMLIB2_LIBS, AC_PATH_GENERIC() does that out of the box already

'other-improvements' into windows-mingw
|
|
|
|
Windows returns pointers to empty strings for non-existent env vars.
|
|
|
|
nowadays every app should use the extended window manager hints exclusively.
|
|
otherwise a race condition might appear between copying the default
config files to .fluxbox/ and executing 'fluxbox-update_configs'. under
macosx this lead to 'fluxbox hangs'.
|

|
|
|
|
not having DISPLAY set (eg: on a headless system) caused fluxbox to crash.
|
|
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.
|
|
'valgrind' reported a lot of code branches based upon uninitialized
variables. some are not identified yet.

No functional change.

nls/translators: typo, plus Translation.m.desc never existed. Never.
