We don't actually want Coverity to complain when a BUG() check can
never fail, since such checks can prevent us from introducing bugs
later on.
Closes ticket 23054. Closes CID 1415720, 1415724.
Instead of choosing a lower-priority job with a 1/37 chance, have
the chance be 1/37 for half the threads, and 1/2147483647 for the
other half. This way if there are very slow jobs of low priority,
they shouldn't be able to grab all the threads when there is better
work to do.
Each piece of queued work now has an associated priority value; each
priority goes on a separate queue.
With probability (N-1)/N, the workers will take work from the highest
priority nonempty queue. Otherwise, they'll look for work in a
queue of lower priority. This behavior is meant to prevent
starvation for lower-priority tasks.
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.
We need to keep these around for TAP and old-style hidden services,
but they're obsolete, and we shouldn't encourage anyone to use them.
So I've added "obsolete" to their names, and a comment explaining
what the problem is.
Closes ticket 23026.
Closes bug 22964. Based on Teor's replacement there, but tries
to put the comment in a more logical place, and explain why we're
actually disabling compression in the first place.
In zstd 1.3.0, once you have called ZSTD_endStream and been told
that your putput buffer is full, it really doesn't want you to call
ZSTD_compressStream again. ZSTD 1.2.0 didn't seem to mind about
this.
This patch fixes the issue by making sure never to call
ZSTD_endStream if there's any more data on the input buffer to
process, by flushing even when we're about to call "endStream", and
by never calling "compress" or "flush" after "endStream".
This change prevents us from generating corrupt messages when we
are confused about codepage settings, and makes Windows errors
consistent with the rest of our logs.
Fixes bug 22520; bugfix on 0.1.2.8-alpha. Patch from "Vort".
- Move some crypto structures so that they are visible by tests.
- Introduce a func to count number of hops in cpath which will be used
by the tests.
- Mark a function as mockable.
The 22081 fix disabled -Wfloat-conversion, but -Wfloat-conversion
didn't exist in every relevant mingw; it was added in GCC 4.9.x some
time, if the documentation can be trusted.
Bug not in any released version of tor.
