0e207f9acb Merge remote-tracking branch 'public/close_file_mapping'
Conflicts:
	src/common/compat.h

Conflict was between replacement of MS_WINDOWS with _WIN32 in
master, and with removal of file_handle from tor_mmap_t struct in
close_file_mapping branch (for bug 5951 fix).

e284894672 Add __attribute__(format)s for our varargs printf/scanf wrappers
It turns out that if you set the third argument of
__attribute__(format) to 0, GCC and Clang will check the format
argument without expecting to find variadic arguments.  This is the
correct behavior for vsnprintf, vasprintf, and vscanf.

I'm hoping this will fix bug 5969 (a clang warning) by telling clang that
the format argument to tor_vasprintf is indeed a format string.

9d41629aa0 Delay getsockname() call until after connect() is done
On Windows, getsockname() on a nonblocking apparently won't work
until the connection is done connecting.  On XP, it seems to fail by
reporting success and declaring that your address is INADDR_ANY.  On the
Win8 preview, though, it fails more loudly and says WSAEINVAL.

Fix for bug 5374; bugfix on 0.1.1.14-alpha.

254504fc14 Have get_parent_directory() handle "/foo" and "/" correctly.
The parent of "/foo" is "/"; and "/" is its own parent.

This would cause Tor to fail if you tried to have a PF_UNIX control
socket in the root directory.  That would be a stupid thing to do
for other reasons, but there's no reason to fail like _this_.

Bug found by Esteban Manchado Velázquez. Fix for bug 5089; bugfix on
Tor 0.2.2.26-beta.  Unit test included.

281a5e4670 Warn and ignore the MyFamily setting if BridgeRelay is also set
Roger explains at
  http://archives.seul.org/tor/talk/Nov-2011/msg00209.html :

  "If you list your bridge as part of your family in the relay
  descriptor, then everybody can learn your bridge fingerprint, and
  they can look up your bridge's descriptor (and thus location) at
  the bridge directory authority."

Now, we can't stop relays from listing bridges, but we can warn when
we notice a bridge listing anybody, which might help some.

This fixes bug 4657; it's a fix on 0.2.0.3-alpha, where bridges were
first introduced.

4c4dd505be Fix a hard-to-trigger memory leak in launch_resolve
To hit this leak, you need to be a relay that gets a RESOLVE request
or an exit node getting a BEGIN or RESOLVE request.  You must either
have unconfigured (and unconfigurable) nameservers, or you must have
somehow set DisableNetwork after a network request arrived but
before you managed to process it.

So, I doubt this is reached often.  Still, a leak's a leak.  Fix for
bug 5916; bugfix on 0.2.3.9-alpha and 0.1.2.1-alpha.

instances of %lf, not more complicated things like %.5lf .  This
patch tries to get everything.

b41dd8069f When ReloadTorrcOnSIGHUP=1, do non-reload activities anyway
Previously, we skipped everything that got invoked from
options_init_from_torrc.  But some of the stuff in
options_act_reversible and options_act is actually important, like
reopening the logs.

Now, a SIGHUP always makes the effects of an options_set() happen,
even though the options haven't changed.

e3243ad5f6 Treat SW_SERVER_HELLO_B as another sign of an SSL handshake
We've been only treating SW_SERVER_HELLO_A as meaning that an SSL
handshake was happening.  But that's not right: if the initial
attempt to write a ServerHello fails, we would get a callback in
state SW_SERVER_HELLO_B instead.

(That's "instead" and not "in addition": any failed attempt to write
the hello will fail and cause the info callback not to get written.)

This tells the windows headers to give us definitions that didn't

The underlying strtoX functions handle overflow by saturating and
setting errno to ERANGE.  If the min/max arguments to the
tor_parse_* functions are equal to the minimum/maximum of the
underlying type, then with the old approach, we wouldn't treat a
too-large value as genuinely broken.

Found this while looking at bug 5786; bugfix on 19da1f36 (in Tor
0.0.9), which introduced these functions.

66dbbc2960 Apply a patch from Gisle Vanem to make tor-gencert build under MSVC
(Note: It makes sense to use tor-gencert on Windows for testing
purposes only.  If you are a directory authority operator, and you
are contemplating running tor-gencert on a Windows box in an actual
production environment, you are probably making a mistake.)
