The problem is that bufferevent_disable() doesn't disable EV_WRITE
when 'connecting' flag is set. However from evhttp_connection_reset()
we want to disable EV_WRITE for sure (we are closing the socket next).
So we add bufferevent_disable_hard(), which acts like
bufferevent_disable(), but resets 'connecting' flag before the call to
the actual handler.
TODO: bufferevent_disable_hard() shouldn't be public, remove it from
event2/bufferevent.h.
9c469db300e1b270a93c6b04c1709ac0f7751136 had started with the conversion
but left out another instance of incorrectly used AM_CFLAGS.
Dave Hart provided the suggestion for this fix.
I don't see how this can burn anybody, but I don't want to take
chances: new build options are something that should be done in an
alpha. To turn -ffunction-sections on, pass
--enable-function-sections to configure.
The main reason for disabling installation is if you're building
libevent as a subpackage for embedding: you want to have your main
package's "make all" build libevent, but you don't want your main
package's "make install" to install libevent.
Fix 1: Use #include "../xyz" rather than #include <../xyz>
Fix 2: util-internal.h includes ipv6-internal.h, which in turn defines
a replacement AF_INET6 on platforms that don't have it. As such,
the AF_INET6 checks shouldn't be needed. (right?)
If the EVHTTP_URI_NONCONFORMANT flag is passed in (which it is when
parsing URIs we get over the wire), then we relax our checks a lot.
Specifically, we do nothing to check for correct characters in the
path, query, and fragment parts of such a URI.
We could do much more here: we could relax our hostname requirements,
deal with spaces differently/better, trap some errors but not others,
etc. But this should solve the worst user-agent compatibility issues
for now; the other issues can wait for a later release.
