1af745d033 signal: new signal handling backend based on signalfd
Linux-specific signal handling backend based on signalfd(2)
system call, and public function event_base_get_signal_method()
to obtain an underlying kernel signal handling mechanism.

041ca00c75 Add a new libevent_global_shutdown() to free all globals before exiting.
Mark Ellzey added a function libevent_shutdown() which calls a set of
private functions:

       * event_free_globals()
       * event_free_debug_globals()
       * event_free_debug_globals_locks()
       * event_free_evsig_globals()
       * evsig_free_globals()
       * evsig_free_globals_locks()
       * evutil_free_globals()
       * evutil_free_secure_rng_globals()
       * evutil_free_secure_rng_globals_lock()

Nick tweaked this libevent global shutdown code:

  - rename the function to emphasize that it's for global resources
  - write more in the doxygen
  - make function brace style consistent
  - add a missing void in a function definition.

8ac3c4c25b Have all visible internal function names end with an underscore.
We haven't had a convention for naming internal functions in -internal.h
versus naming visible functions in include/**.h.  This patch changes every
function declared in a -internal.h file to be named ending with an
underscore.

Static function names are unaffected, since there's no risk of calling them
from outside Libevent.

This is an automatic conversion.  The script that produced was made by
running the following script over the output of

ctags --c-kinds=pf -o - *-internal.h |  cut -f 1 | sort| uniq

(GNU ctags was required.)

3f8c7cd035 Convert include-guard macro convention to avoid reserved identifiers
Previously we used include-guards with names like _EVENT2_EVENT_H_.
But C reserves macros beginning with an underscore for use by the
system.  This patch converts all include guards for files like
include/event2/<fname.h> to be of form EVENT2_<FNAME_H>_INCLUDED_,
and all Libevent 1.x headers in include/<fname.h> to be of the form
EVENT1_<FNAME_H>_INCLUDED_, and all internal libevent headers with
names like <fname.h> to the form <FNAME_H>_INCLUDED_.

FNAME_H is here derived from fname.h by replacing every
non-macro-usable character in fname.h with an underscore, and
putting every remaining character in uppercase.

This is an automatic conversion.  The script that produced was made by
running the following script over all header files:

=====
#!/usr/bin/perl -w

# Run this on every .h file except config.h, sys/queue.h, WIN32/event2/event-config.h

use strict;

my %macros = ();
my %skipped = ();
FILE: for my $fn (@ARGV) {
    my $f = $fn;
    if ($fn !~ /^\.\//) {
	$f = "./$fn";
    }
    if ($f eq './config.h' or
	$f =~ m#/tree.h$# or
	$f =~ m#/queue.h# or
	$f =~ m#/event-config.h# or
	$f =~ m#/evconfig-private.h#) {
	$skipped{$fn} = 1;
	next FILE;
    }
    $skipped{$fn} = 0;
    open(F, $fn);
    while (<F>) {
	if (/^#ifndef ([A-Za-z0-9_]+)/) {
	    $macros{$fn} = $1;
	    next FILE;
	}
    }
}

print "#!/usr/bin/perl -w -i -p\n\n";
for my $fn (@ARGV) {
    if (! exists $macros{$fn}) {
	print "# No macro known for $fn!\n" if (!$skipped{$fn});
    } else {
	if ($macros{$fn} !~ /_H_?$/) {
	    print "# Weird macro for $fn...\n";
	}
	my $goodmacro = uc $fn;
	$goodmacro =~ s#^\./##;
	$goodmacro =~ s#INCLUDE/EVENT2#EVENT2#;
	$goodmacro =~ s#INCLUDE/#EVENT1_#;
	$goodmacro =~ s#TEST/##;

	$goodmacro =~ s#[\/\-\.]#_#g;

	print "s/(?<![A-Za-z0-9_])$macros{$fn}(?![A-Za-z0-9_])/${goodmacro}_INCLUDED_/g;\n"
    }

68120d9b00 Convert event-config.h macros to avoid reserved identifiers
C reserves all identifiers beginning with an underscore for system
use.  But we had been mangling our autoconf identifiers with the
prefix "_EVENT_" to avoid conflict with other programs.

Instead, we will now use the prefix "EVENT__".  With any luck, the
double-underscore will still hint "here be dragons" to anybody
tempted to think that event-config.h is a stable api.

This is an automatically generated patch.  The script that produced
it was made by running this script over config.h.in:

=====

#!/usr/bin/perl -w

# Run this on config.h.in

use strict;

my %macros = ();

while (<>) {
    if (/^# *undef +([A-Za-z0-9_]+)/) {
	$macros{$1} = 1;
    }
}

print "#!/usr/bin/perl -w -i -p\n\n";
for my $k (sort keys %macros) {
    print "s/(?<![A-Za-z0-9_])_EVENT_$k(?![A-Za-z0-9_])/EVENT__$k/g;\n";
}

== And the script that it generated was then run over all .c and .h files:
#!/usr/bin/perl -w -i -p

95a7d418ab Make default signal backend fully threadsafe
Jason Toffaletti discovered with helgrind that our signal handler was
messing with evsig_base, which can be set from lots of places in the
code.  Ordinarly, we'd just stick a lock on it, except that it is
illegal (and genuinely error-prone) to call pthread_mutex_acquire()
from inside a signal handler.

The solution is to only store the fd we write to in a static variable,
write the signal number to the fd, and put evsig_cb in charge of
activating signal events.

I have no idea how we'll cope if we want to enable this to handle
siginfo (where available) in the future.

720bd933c8 Warn when using the error-prone EV_SIGNAL interface in an error-prone way. Also, fix a couple of race conditions in signal.c
When using the signal.c signal backend, Libevent currently only allows
one event_base to actually receive signals at a time.  (This has been
the behavior since at least 1.4 and probably much earlier.)  Now, we
detect and warn if you're likely to be racing about which signal goes
to which thread.

We also add a lock to control modifications of the evsig_base field,
to avoid race conditions like those found by Jason Toffaletti.

Also, more comments.  Comments are good.

8c66eb2e9b Try to contain the failure when we are running without socketpair().
Some win32 systems (mostly those using Kaspersky, it would seem)
prevent us from faking socketpair().  This makes our signal
notification code just not work.  Our response since 1.4 has been to
assert.  For users who would rather work without signals than not work
at all, this has been a regression from 1.3e.

This patch makes adding signal events fail in this case; there's no
reason to kill the whole process.
