In the Linux kernel, the BUG() macro causes an instant panic. Our
BUG() macro is different, however: it generates a nonfatal assertion
failure, and is usable as an expression.
Additionally, this patch tells util_bug.h to make all assertion
failures into fatal conditions when we're building with a static
analysis tool, so that the analysis tool can look for instances
where they're reachable.
Fixes bug 23030.
Wow, it sure seems like some compilers can't implement isnan() and
friends in a way that pleases themselves!
Fixes bug 22915. Bug trigged by 0.2.8.1-alpha and later; caused by
clang 4.
Clang didn't like that we were passing uint64_t values to an API
that wanted uint32_t. GCC has either not cared, or has figured out
that the values in question were safe to cast to uint32_t.
Fixes bug22916; bugfix on 0.2.7.2-alpha.
When setting the maximum number of connections allowed by the OS,
always allow some extra file descriptors for other files.
Fixes bug 22797; bugfix on 0.2.0.10-alpha.
We just have to suppress these warnings: Mingw's math.h uses gcc's
__builtin_choose_expr() facility to declare isnan, isfinite, and
signbit. But as implemented in at least some versions of gcc,
__builtin_choose_expr() can generate type warnings even from
branches that are not taken.
Fixes bug 22801; bugfix on 0.2.8.1-alpha.
As of ac2f6b608a in 0.2.1.19-alpha,
Sebastian fixed bug 888 by marking descriptors as "impossible" by
digest if they got rejected during the
router_load_routers_from_string() phase. This fix stopped clients
and relays from downloading the same thing over and over.
But we never made the same change for descriptors rejected during
dirserv_add_{descriptor,extrainfo}. Instead, we tried to notice in
advance that we'd reject them with dirserv_would_reject().
This notice-in-advance check stopped working once we added
key-pinning and didn't make a corresponding key-pinning change to
dirserv_would_reject() [since a routerstatus_t doesn't include an
ed25519 key].
So as a fix, let's make the dirserv_add_*() functions mark digests
as undownloadable when they are rejected.
Fixes bug 22349; I am calling this a fix on 0.2.1.19-alpha, though
you could also argue for it being a fix on 0.2.7.2-alpha.
