Another try to get the signal/dead child recovery stuff right.
Could the brave signal crew (TM) (Austin, Garry, Raphael, Tim)
please do bad tests to the new code? I removed all strange
constants (SA_NODEFER etc.) and used only glib and POSIX stuff.
* app/main.c
* libgimp/gimp.c:
- Call gimp_signal_private() with no flags to enforce a proper
sigaction() behaviour (block signals while handler is active).
- Removed the reentrancy guards from the handlers.
- Renamed the handlers.
- Ignore SIGPIPE in the app and in plugins.
- Re-introduced the SIGCHLD handler because it should work
now. Also added a SIGCHLD handler to libgimp/gimp.c.
* app/errors.c
* libgimp/gimp.c: in the signal handler, unblock all signals
with sigprocmask() before calling g_on_error_query() because
gdb otherwise inherits the blocked signals and does nothing.
Wrapped the statements with "if (TRUE) { }" blocks so it's
easy to make the stack trace a command line option.
* app/plug_in.c
* libgimp/gimp.c: listen for G_IO_ERR and G_IO_HUP on the read
channels. In the app, pop up an error message and clean up the
plugin. In plugins, clean up and exit.
* libgimp/gimpwire.c: removed the "plug-in chrashed?" message
and print the program's name with all error messages.
* plug-ins/helpbrowser/helpbrowser.c: typo.
* app/app_procs.c
* app/gdisplay_color.[ch]
* app/gdisplay_color_ui.c: make the ui usable
* app/gdisplay.c: enable cdisplay support
* modules/Makefile.am
* modules/cdisplay_gamma.c: moved gamma functionality to separate
-Yosh
* libgimp/gimp.c: No need for <io.h> on Win32.
* libgimp/{gimp,gimpui}.def: Add two entry points.
* libgimp/gimp.h: Can't use __declspec(dllexport) for PLUG_IN_INFO
when compiling with gcc on Win32. Also handle __argc, __argv and
_stdcall differently with gcc on Win32
* libgimp/gimpenv.c: Include <string.h>.
* libgimp/gimpfeatures.h.in: Remove lots of extraneous trailing blanks.
* libgimp/gimpfileselection.c: Include <glib.h> early, see above.
* libgimp/{gimpwire,parasite}.c: Test for NATIVE_WIN32, not
_MSC_VER.
* libgimp/makefile.msc: Miscellaneous updates. The gimpi library
is now built as a static library.
