Apache 2.2 -X commanlinde option broken?
Hi y'all
When I start my httpd 2.2.0 (prefork mpm on solaris) using the -X
option for some automated testing of a module I wrote, I cannot stop the
process correctly anymore (works in httpd 2.0.x and earlier).
It seems that the SIGTERM signal is just ignored by the process. (Only
thing I can do is a "kill -9". An "httpd -k stop" doesn't work either
(seems to just send a SIGTERM to the process).
Is the -X option not supported anymore? Or is it just broken?
(An no, it does not have to do anything with my module, as it behaves
just the same even when my module isn't even anywhere on the file
system ;-)
truss output of a SIGTERM signal in httpd 2.2.0:
signotifywait() = 15
Received signal #15, SIGTERM, in accept() [caught]
siginfo: SIGTERM pid=6129 uid=1001
lwp_sigredirect(1, SIGTERM, 0xFEC0FC6C) = 0
signotifywait() = 25
accept(3, 0x0012DF90, 0x0012DF7C, 1) Err#4 EINTR
lwp_sigredirect(0, SIGCONT, 0x00000000) = 0
lwp_mutex_wakeup(0xFEEF34F8) = 0
lwp_mutex_lock(0xFEEF34F8) = 0
sigprocmask(SIG_SETMASK, 0xFEEECFB8, 0x00000000) = 0
sigprocmask(SIG_SETMASK, 0xFEEF8CE0, 0x00000000) = 0
setcontext(0xFFBEE9E8)
accept(3, 0x0012DF90, 0x0012DF7C, 1) (sleeping...)
signotifywait() (sleeping...)
door_return(0x00000000, 0, 0x00000000, 0) (sleeping...)
lwp_cond_wait(0xFEEF34E8, 0xFEEF34F8, 0xFEEECD80) (sleeping...)
and the same with httpd 2.0.53 (which works as expected):
signotifywait() = 15
Received signal #15, SIGTERM, in accept() [caught]
siginfo: SIGTERM pid=6129 uid=1001
lwp_sigredirect(1, SIGTERM, 0xFEC0FC6C) = 0
signotifywait() = 25
accept(3, 0x0011EE64, 0x0011EE84, 1) Err#4 EINTR
lwp_sigredirect(0, SIGCONT, 0x00000000) = 0
sigprocmask(SIG_SETMASK, 0xFEE9CFB8, 0x00000000) = 0
close(5) = 0
close(4) = 0
llseek(0, 0, SEEK_CUR) = 17951
_exit(0)
TIA for any insight

FWIW: It really is broken: I have the same problem on Redhat 8 and
Joachim Zobel reported the same for debian etch (x86) on a different
mailing list.
I can't imagine that this is a desired behavior (as it does not make
sense not being able to properly shutdown httpd) so I'll submit a bug.
