Now that half the threads are permissive and half are strict, we
need to make sure we have at least two threads, so that we'll
have at least one of each kind.
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.
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".
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.
Relay operators (especially bridge operators) can use this to lower
or raise the number of consensuses that they're willing to hold for
diff generation purposes.
This enables a workaround for bug 22883.
This reverts part of commit 706c44a6ce.
It was a mistake to remove these includes: they were needed on
systems where we have openssl 1.1.0 *and* libscrypt, and where we
were validating the one against the other.
Fixes bug 22892; bugfix on 0.3.1.1-alpha.
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".
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.
