 99 2016-04-16T11:54:43  <nsh> aye, but doesn't look so bad on inspection

102 2016-04-16T11:57:26  <sipa> there are calls at first startup, inside processmessages, and before signing in the wallet

105 2016-04-16T11:59:35  <gmaxwell> I earlier made the observation to sipa that getting away from openssl's RNG has three parts:   A combiner to take OS randomness at the point of key usage; an internal CSPRNG; and a seeding process.  The internal CSPRNG has implementation annoyances around things like thread safty. But we can do the other two parts with openssl still there, taking the places of the eventual internal CSPRNG.
106 2016-04-16T11:59:46  <gmaxwell> And so that would be a good way to make progress on this.
107 2016-04-16T12:00:39  <nsh> makes sense

111 2016-04-16T12:05:40  <sipa> well you need locking on your entropy pool
112 2016-04-16T12:05:48  <sipa> at the very least
113 2016-04-16T12:06:23  <sipa> or perhaps per-thread entropy pools (using thread local storage), which only under certain conditions request entropy from the global process-wide one
114 2016-04-16T12:07:53  <sipa> and these are things you can't easily do in a portable C library (which is something that was requested before in #5885 and #7162)

126 2016-04-16T13:55:37  <Chris_Stewart_5> With these version bits we could make radical departures to Script as we see it now right? For instance trying to type Script?

131 2016-04-16T14:04:50  <Luke-Jr> well, that's segwit's witness script versioning more than versionbits..
132 2016-04-16T14:06:26  <sipa> Luke-Jr: oh, absolutely
133 2016-04-16T14:06:38  <sipa> though the combination makes it even easier
134 2016-04-16T14:10:23  <Chris_Stewart_5> I'll have to read up on the difference
135 2016-04-16T14:10:45  <sipa> versionbits is about being to roll out multiple softforks in parallel
136 2016-04-16T14:11:02  <sipa> segwit script versioning means every script change can be turned into a softfork
137 2016-04-16T14:11:47  <Chris_Stewart_5> intuitively I thought the script verisioning just allows for versions similar to other PLs - for instance python 2.7.x is that more or less correct?
138 2016-04-16T14:12:29  <sipa> right now, we can't for example change checksig to use a different signature type
139 2016-04-16T14:13:08  <sipa> (that would be a hardfork)
140 2016-04-16T14:13:11  <Chris_Stewart_5> sure
141 2016-04-16T14:13:28  <sipa> with script versioning, we can just change checksig's definition
142 2016-04-16T14:13:52  <sipa> wumpus or any other gitian building, are there any known problems with certain gitian virtualizations? (virtualbox, KVM, LXC, ...) ?
143 2016-04-16T14:14:22  <sipa> or are they all known to work?
144 2016-04-16T14:14:56  <sipa> oh, that's the outer layer virtualization
145 2016-04-16T14:14:57  <sipa> nvm
146 2016-04-16T14:15:12  <Chris_Stewart_5> What about size requirements? That is vague question but perhaps we decide not to use SHA256 anymore and switch to another hash algorithm that produces a different size of digest compared to SHA256
147 2016-04-16T14:15:32  <sipa> yes, maybe
148 2016-04-16T14:15:35  <Chris_Stewart_5> Could this 'bleed' out of the script versioning system into other parts of consensus code?
149 2016-04-16T14:15:40  <Chris_Stewart_5> if that makes any sense
150 2016-04-16T14:15:50  <sipa> it can be made not to
