17:11 <lopex> enebo: I cant find any lazy byte[] reading java apis lolz

17:11 alex0ptr has quit [Ping timeout: 240 seconds]

17:11 <lopex> enebo: the other thing is the newlines

17:12 <nirvdrum> lopex: What are you trying to do?

17:13 <lopex> nirvdrum: lazy read lines via byte[]

17:13 <lopex> frmo a file

17:13 <lopex> *from

17:14 <lopex> nirvdrum: there's a couple of questions, like imagine there line lengths [1, 10000000000, 2]

17:14 <nirvdrum> Can't the various InputStream classes do that?

17:14 <lopex> nirvdrum: not for jcodings apis

17:14 <nirvdrum> Why's that?

17:15 <lopex> nirvdrum: you need to grow a byte[] as needed anyways

17:15 <lopex> and then possibly discard it for another line

17:15 <lopex> so it doesnt take up memory

17:15 <lopex> or reuse it if another line is of similar size

17:16 <lopex> nirvdrum: well, talking about most performant solution

17:16 camlow325 has joined #jruby

17:16 <lopex> so you need to juggle those byte[] lines anyways as I see it

17:17 <lopex> nirvdrum: also, there's windows new lines distinction, and you need to have read a portion of it

17:18 enebo_ has quit [Quit: enebo_]

17:19 <lopex> nirvdrum: or am I overcomplicating it ?

17:20 <lopex> nirvdrum: it's enough involving so it's worth providing separate jcodings apis imho

17:20 <lopex> er, involving enough :P

17:20 <lopex> of course naive impl would be easy

17:23 tcrawley is now known as tcrawley-away

17:23 <nirvdrum> Since you ultimately need the full byte[] anyway, maybe preallocating based on file size and then wrapping in a ByteBuffer would work?

17:24 <lopex> that's what I want to avoid

21:43 <snowp> are there any good resources around on indy/PIC/etc.? trying to understand how call site caching works in jruby

21:50 <nirvdrum> snowp: I'm not sure that there are any design docs. I'm sure headius or enebo would be happy to get you started though.

22:00 <lopex> snowp: you'd lie to dive in the history of pics like in self ?

22:01 <snowp> just trying to get some more context around them

22:01 <lopex> snowp: I think Oracle graal papers will be more up to date and easier to follow

22:03 <snowp> alright ill take a look at those. thanks

22:06 <chrisseaton> snowp: http://rubybib.org

22:07 <lopex> snowp: the earlier papers were wrt self (a smalltalk impl)

22:08 <lopex> snowp: chrisseaton is the one to listen to

22:09 <chrisseaton> snowp: this is the definitive paper http://hoelzle.org/publications/ecoop91.pdf on PIC

22:10 <lopex> chrisseaton: does it do reordering wrt frequency ?

22:10 <chrisseaton> lopex: we don't, I don't know anyone else who does, but probably someone

22:11 <snowp> oh man youve given me so much reading material. thanks again both of you!

22:11 <lopex> chrisseaton: I quess it's the question how you define steady state right ?

22:13 <nirvdrum> snowp: Oops. I didn't realize you were looking for general stuff. I thought you wanted to know exactly what JRuby was doing.

22:16 <lopex> simple PIC is the more straight forward thing to do anyways

22:16 <lopex> it;s based almost like on the hot spot hypotesis

22:18 <lopex> jeeeze

22:18 <lopex> I think I should just shut up

22:19 <snowp> nirvdrum: either or, im just trying to get a better grasp of this whole indy world

22:39 <chrisseaton> snowp: there are probably less than a hundred people in the world who use that API (of course millions *use* it via using the software but I mean people who write against the API) so there aren't many documents. You kind of are expected to know the right people anyway :)

22:41 <snowp> hah that explains why id never heard about it before

22:42 <snowp> so its only really used to implement dynamic languages? are there other use cases?

22:44 <lopex> why ? you can profile c++ just as well

22:45 <lopex> you can have an offline profile, just like the whole spectrum
