2015-01-31Improve I18n supportMathias Gumz1-5/+8
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.
2014-02-18Fix race condition on shutdownMathias Gumz1-0/+191
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*
