44ad734573 Merge remote-tracking branch 'public/3122_memcmp_squashed' into bug3122_memcmp_022 
Conflicts throughout.  All resolved in favor of taking HEAD and
adding tor_mem* or fast_mem* ops as appropriate.

59f9097d5c Hand-conversion and audit phase of memcmp transition 
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

2f8e96b553 Fix log message when we have too few dirauths 
The calculation of when to send the logmessage was correct, but we
didn't give the correct number of relays required: We want more than
half of all authorities we know about. Fixes bug 2663.

cae769d646 Segfault less during consensus generation without params

trying to make a new consensus from the votes. Let's change that.

512cebadad For integers, if !(E<G), then we can infer that E>=G. 
This means that "if (E<G) {abc} else if (E>=G) {def}" can be replaced with
"if (E<G) {abc} else {def}"

Doing the second test explicitly made my mingw gcc nervous that we might
never be initializing casename.

eb10d441b6 Fix 64-bit printf issues in consensus-bw-weights5-merge. 
For my 64-bit Linux system running with GCC 4.4.3-fc12-whatever, you
can't do 'printf("%lld", (int64_t)x);' Instead you need to tell the
compiler 'printf("%lld", (long long int)x);' or else it doesn't
believe the types match.  This is why we added U64_PRINTF_ARG; it
looks like we needed an I64_PRINTF_ARG too.

50d6960332 Cast our weights down to ints from int64. 
They are capped to be between 0 and weight_scale (10000) by the code
just before the snprintf.

0c1b3070cf Now that FOO_free(NULL) always works, remove checks before calling it. 2009-12-12 02:07:59 -05:00
Sebastian Hahn
3807db001d *_free functions now accept NULL 
Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.

This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.
