way? 18:49 <+iant> anticw: the compiler has to note when a pointer is copied or discarded 18:49 <+iant> in order to do efficient reference counting 18:50 < anticw> iant: the long-term plan is reference counts vs something like mark and sweep? 18:50 <+iant> yes, that is what we currently plan 18:56 < anticw> iant: how large are the counters? it seems i could overflow a 32-bit one w/o much effort 18:58 <+iant> anticw: actually it would take a fair amount of effort because you would have to make that many copies of the pointer 18:58 <+iant> anticw: I think if you did that we would just never collect the pointer 18:59 < anticw> iant: it might be contrived ... but not hard 18:59 < anticw> array/slice indicies being ints already bite in some cases 18:59 < anticw> i dont know of a clean way to deal with that 19:00 <+iant> anticw: your program would have to run for a while 19:00 <+iant> anticw: yeah, I'm not sure I agree with using 32-bit indices for slices, but it does make the 99% case faster 19:01 < anticw> iant: i dont want 64-bit though ... not by default 19:01 < anticw> because i almost never need it ... but 4GB is really small now days 19:01 < anticw> even for cellphones ... many have 16GB of flash for example 19:02 <+iant> I think the question is how often you accidentally have a single slice more than 4G 19:02 <+iant> if you know the slice can be that large, you can partition 19:02 <+iant> which I agree is inconvenient 19:02 < anticw> segments 19:02 < anticw> again 19:02 < anticw> that was a failure 19:02 -!- Wiz126 [i=Wiz126@72.20.225.240] has joined #go-nuts

<+iant> I would just write a separate type with methods for large data sets 19:07 <+iant> like container/vector 19:07 <+iant> but using int64 19:07 < anticw> container/vector right now is horrible

I find the staging idea unintuitive. 23:42 < mrd`> nsf: I always run "$vc diff" before "$vc commit" to double check what I'm about to commit. 23:43 < nsf> it's unintuitive when you're making a mess in commits.. but when you want "nice and sweet" commits where each change makes sense.. it really helps 23:43 < nsf> basicly you're doing mess in sources as usual and the using git diff and git diff --cached make nice commits :D 23:43 < nsf> then* 23:43 < mrd`> "diff --cached" is a lot longer to type than "commit -a". 23:44 < nsf> sometimes it's hard to do just right changes in a source tree 23:44 < nsf> for example while working on a big feature X you've noticed some silly debug print statement 23:45 < nsf> it's bad to include it in the commit with big feature X, but you really don't want to leave it there 23:45 < mrd`> Hm. 23:45 < nsf> so, you simply remove and then make a separate commit for it :D 23:45 < nsf> "staging" helps managing things 23:46 < mrd`> I guess. 23:49 -!- encolpe [n=encolpe@gai69-3-82-235-15-3.fbx.proxad.net] has quit ["Leaving"] 23:53 < usausa> If you want to do this kind of thing, then the "record" extension does this for you. You use it instead of "commit". It only works to the patch "hunk" level so if your silly debug print statement is in the middle of the stuff you are altering you are out of luck. 23:55 < usausa> http://mercurial.selenic.com/wiki/RecordExtension 23:59 -!- Xera` [n=brit@87-194-208-246.bethere.co.uk] has joined #go-nuts --- Log closed Wed Jan 27 00:00:50 2010
