Make signal handlers async-signal-safe

[browser-switch] / Changelog

version 3.3:
* add support for Opera Mobile
* only offer installed browsers in the config GUI
* make continuous mode operation the default; disable non-continuous-mode on
  Fremantle (needed for correct operation on D-Bus system bus)
* Fremantle: major overhaul of MicroB launching to improve robustness; should
  result in speed and behavior indistinguishable from when Browser Switchboard
  isn't installed when MicroB is configured as default browser
* fall back to the built-in default if the user's configured default browser
  isn't installed
* listen on D-Bus system bus as well as session bus, to accommodate some broken
  applications that send their requests on the system bus
* Fremantle: start browser-switchboard on X session startup, and also prestart
  MicroB if it's the default browser or the user asks for it
* Fremantle: prestart MicroB when the user changes to MicroB as the default
  browser
* introduce a command-line config utility; this is mainly intended to give
  browser vendors a way to set their browser as the default
* config UI: provide a description for users who don't know what MicroB is;
  thanks Emanuele Cassioli for pointing out the need
* major rewrite of configuration loading/saving code

version 3.2:
* make the "Web" menu entry and /usr/bin/browser open the default browser, and
  provide a new "MicroB" menu entry and /usr/bin/microb script for launching
  MicroB; the previous behavior was counterintuitive and difficult to discover
* Fremantle: fix launching and closing MicroB on Fremantle; thanks Faheem
  Pervez and Uwe Kaminski for extensive testing
* Fremantle: force the Ovi Store bookmark to open in MicroB, since Ovi Store
  doesn't load in other browsers; thanks ToJa92 of t.m.o for reporting
* add ability to send debug output to syslog and new config setting ("logging")
  to control where debug output goes; thanks Faheem Pervez for the suggestion
* close stdin/stdout/stderr in child processes before the exec(), to make debug
  output on stdout less noisy
* fix some abuses of the D-Bus API in launcher.c:launch_tear()
* make sure a running browserd is detected correctly on all devices so that we
  don't try to launch another one; thanks Faheem Pervez for reporting
* ensure that only one browser-switchboard is active at any time
* update build system; we now have "diablo" and "fremantle" targets that build
  binaries for the selected OS release
* link binaries with -Wl,--as-needed to eliminate unnecessary dependencies

version 3.1:
* add a new, more finger-friendly GUI for Fremantle, based on work by
  Faheem Pervez (build UI with EXTRA_CPPFLAGS=-DFREMANTLE)
* make sure reconfig signal (SIGHUP) doesn't interrupt dispatch of a request
  when continuous mode is off
* disable autocapitalization and predictive text features for the
  other_browser_cmd entry in the UI
* add support for EXTRA_CPPFLAGS in Makefiles, to allow package builds to pass
  feature/configuration defines; add EXTRA_LDFLAGS too, just in case

version 3.0:
* fix the UI so that it looks for C browser-switchboard processes to send
  SIGHUP to, not Python browser-switchboards 
* add support for EXTRA_CFLAGS in Makefiles, to allow package builds to pass
  additional optimization flags
* replace calls to `pkg-config dbus-1` in config-ui/Makefile with calls to
  `pkg-config libosso` instead; asking for dbus-1 was incorrect and covering
  up a problem that caused maemo extras-devel autobuilds to fail

version 3.0rc1:
* reimplement the main browser-switchboard process in C, which leads to much
  faster startup times and much lower memory usage
* implement a configuration UI, which can be used as a standalone app or as a
  hildon-control-panel applet
* default to launching MicroB if no config file is found -- with a config UI,
  it's best to keep things unchanged in a fresh install and let the user
  configure them him/herself
* EXPERIMENTAL Fremantle support

version 2.2:
* rename the package to browser-switchboard
* move the config file to $HOME/.config/browser-switchboard, and fall back
  to the old location if no config file is found
* if no config file is found and Tear isn't installed, launch MicroB;
  this avoids breaking link opening on a system with a freshly installed
  browser-switchboard package and Tear not installed
* substantial documentation update

version 2.1:
* Steven Luo is now the primary maintainer
* use a config file, /home/user/.config/browser-proxy, if available
* add support for launching Fennec and Midori out of the box
* introduce a config option default_browser for selecting the default browser
  ("tear", "microb", "fennec", "midori", "other")
* add support for launching an arbitrary browser using the other_browser_cmd
  config option
* run maemo-invoker directly instead of /usr/bin/browser to avoid a loop when
  /usr/bin/browser is a wrapper invoking this script
* add a new, private D-Bus method for a /usr/bin/browser wrapper to use to
  launch MicroB with a URI

version 2.0:
* several patches contributed by Steven Luo:
  - only launch one window if Tear isn't already running
  - use gobject instead of gtk+ for main loop, uses less memory
  - use python dbus interface instead of shelling out for dbus-send
  - add 'continuous mode' option to keep proxy running (faster response)
  - kill browserd on exit if launched from the script
  - add option to use MicroB by default

version 1.5:
* added mime_open method used by File manager to open .html files

version 1.4:
* can now manually launch MicroB/browser -- while open, it will be used instead
* without --print-reply, the initial launching message seems to get lost

version 1.3:
* sniff for local paths, prefix with file:// (fixes feedcircuit)

version 1.2:
* removed return values, added osso_browser/request namespace (fixes Pidgin)

version 1.1:
* fixed wrong capitalization in dbus message

version 1.0:
* initial release
