1022016-04-16T11:57:26  <sipa> there are calls at first startup, inside processmessages, and before signing in the wallet

1052016-04-16T11:59:35  <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.
1062016-04-16T11:59:46  <gmaxwell> And so that would be a good way to make progress on this.
1072016-04-16T12:00:39  <nsh> makes sense

1112016-04-16T12:05:40  <sipa> well you need locking on your entropy pool
1122016-04-16T12:05:48  <sipa> at the very least
1132016-04-16T12:06:23  <sipa> or perhaps per-thread entropy pools (using thread local storage), which only under certain conditions request entropy from the global process-wide one
1142016-04-16T12:07:53  <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)

1262016-04-16T13:55:37  <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?

1282016-04-16T13:56:01  <sipa> yes

1312016-04-16T14:04:50  <Luke-Jr> well, that's segwit's witness script versioning more than versionbits..
1322016-04-16T14:06:26  <sipa> Luke-Jr: oh, absolutely
1332016-04-16T14:06:38  <sipa> though the combination makes it even easier
1342016-04-16T14:10:23  <Chris_Stewart_5> I'll have to read up on the difference
1352016-04-16T14:10:45  <sipa> versionbits is about being to roll out multiple softforks in parallel
1362016-04-16T14:11:02  <sipa> segwit script versioning means every script change can be turned into a softfork
1372016-04-16T14:11:47  <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?
1382016-04-16T14:12:29  <sipa> right now, we can't for example change checksig to use a different signature type
1392016-04-16T14:13:08  <sipa> (that would be a hardfork)
1402016-04-16T14:13:11  <Chris_Stewart_5> sure
1412016-04-16T14:13:28  <sipa> with script versioning, we can just change checksig's definition
1422016-04-16T14:13:52  <sipa> wumpus or any other gitian building, are there any known problems with certain gitian virtualizations? (virtualbox, KVM, LXC, ...) ?
1432016-04-16T14:14:22  <sipa> or are they all known to work?
1442016-04-16T14:14:56  <sipa> oh, that's the outer layer virtualization
1452016-04-16T14:14:57  <sipa> nvm
1462016-04-16T14:15:12  <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
1472016-04-16T14:15:32  <sipa> yes, maybe
1482016-04-16T14:15:35  <Chris_Stewart_5> Could this 'bleed' out of the script versioning system into other parts of consensus code?
1492016-04-16T14:15:40  <Chris_Stewart_5> if that makes any sense
1502016-04-16T14:15:50  <sipa> it can be made not to
