fix compile-time warnings.

One fix (in CCrashWatcher::GetPluginsInfo) needs closer look,
others are "trivially correct"

fix bug 54: make abrt (without -d) report initialization errors

2009-08-06T15:23:02+00:00

Example (strace):

10053 17:18:58.384259 close(0)          = 0
10053 17:18:58.384293 open("/dev/null", O_RDWR) = 0
    child is created:
10053 17:18:58.384354 clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7f50eea1c880) = 10054
    parent sleeps, child initializes:
10053 17:18:58.384678 nanosleep({0, 100000000},  
10054 17:18:58.384751 setsid()          = 10054
10054 17:18:58.384794 close(1)          = 0
10054 17:18:58.384828 close(2)          = 0
10054 17:18:58.384870 dup(0)            = 1
10054 17:18:58.384901 dup(0)            = 2
10054 17:18:58.385099 open("/usr/app/abrt-TEST/var/etc/abrt/abrt.conf", O_RDONLY) = 3
...

10054 17:18:58.449148 inotify_add_watch(4, "/usr/app/abrt-TEST/var/cache/abrt", IN_CREATE) = 1
10054 17:18:58.449228 fstat(4, {st_mode=S_IFDIR|0600, st_size=0, ...}) = 0
10054 17:18:58.449288 fcntl(4, F_GETFL) = 0 (flags O_RDONLY)
    child: initialization is done, it signals parent:
10054 17:18:58.449346 getppid()         = 10053
10054 17:18:58.449380 kill(10053, SIGTERM) = 0
10054 17:18:58.449427 write(1, "Debug: Running...\n"..., 18 
10053 17:18:58.449447 <... nanosleep resumed> 0) = ? ERESTART_RESTARTBLOCK (To be restarted)
10054 17:18:58.449470 <... write resumed> ) = 18
10054 17:18:58.449494 open("/usr/app/abrt-TEST/var/run/abrt.lock", O_RDWR|O_CREAT, 0640 
10053 17:18:58.449517 --- SIGTERM (Terminated) @ 0 (0) ---
10054 17:18:58.449565 <... open resumed> ) = 5
10053 17:18:58.449583 rt_sigreturn(0xf 
10054 17:18:58.449607 fcntl(5, F_SETLK, {type=F_WRLCK, whence=SEEK_CUR, start=0, len=0} 
    sleep(100ms) is interrupted:
10053 17:18:58.449629 <... rt_sigreturn resumed> ) = -1 EINTR (Interrupted system call)
10054 17:18:58.449664 <... fcntl resumed> ) = 0
10054 17:18:58.449688 unlink("/usr/app/abrt-TEST/var/run/abrt.pid" 
    parent exits 0 because it got TERM which means child is ok:
10053 17:18:58.449713 exit_group(0)     = ?

On exit, take care to emit consistent exit status.

If we were Ctrl-C'ed, then we should exit by killing ourself, not exit(N).

rework unsafe handling of SIGINT/SIGTERM

2009-07-17T13:52:27+00:00

Signals are asynchronous. It is unsafe to perform such complex
operations in a signal handler. I changed signal handler
to just set a flag, and added an event source which returns an event
when this variable is set. The action is to stop event loop.
Execution then falls through to program exit.

Restore /proc/sys/kernel/core_pattern on error exit.

The bug was observed when dbus-abrt.conf is missing.
