If a file doesn't use the file command (either \file or @file),
Doxygen won't try to process it.
These declarations also turned up a doxygen warning for
crypto_ope.c; I fixed that too.
This can't actually result in a null pointer dereference, since
pub_excl and sub_excl are only set when the corresponding smartlists
are nonempty. But coverity isn't smart enough to figure that out,
and we shouldn't really be depending on it.
Bug 29938; CID 1444257. Bug not in any released Tor.
Having the numbers in those messages makes some of the unit test
unstable, by causing them to depend on the initialization order of
the naming objects.
We want the DISPATCH_ADD_PUB() macro to count as making a
DECLARE_PUBLISH() invocation "used", so let's try a new approach
that preserves that idea. The old one apparently did not work for
some versions of osx clang.
This code tries to prevent a large number of possible errors by
enforcing different restrictions on the messages that different
modules publish and subscribe to.
Some of these rules are probably too strict, and some too lax: we
should feel free to change them as needed as we move forward and
learn more.
This "publish/subscribe" layer sits on top of lib/dispatch, and
tries to provide more type-safety and cross-checking for the
lower-level layer.
Even with this commit, we're still not done: more checking will come
in the next commit, and a set of usability/typesafety macros will
come after.
