Clean-up and re-working of Promise.

The outside API remains largely the same, except the constructor is now only taking :$scheduler. The main change is that Promise is no longer tied to running code at all. Rather, that's just what the run factory method and then methods set up. Promise.sleep(...) is also mostly delegated to the Scheduler. This makes Promise more focused around its synchronization primitive nature, and puts the other Promise factories on a more even footing.		 00:02
jnthn ...and also means you can create a TestScheduler to test your Promise.sleep-ing stuff. 00:03

sisar Hello. I'm unable to install rakudo. Full log: paste.ubuntu.com/6335241/ . What am I doing wrong ? 11:36
FROGGS ohh, you build on cygwin? 11:39
diakopter sisar: seems that library was built on line 400
FROGGS sisar: you can't use the windows msi by any chance?
sisar FROGGS: yes, Cygwin 11:40
diakopter .. however, it was copied to dynext, not /home/siddhant/rakudo/install/dynext
another prefix fail
sisar FROGGS: Cygwin would be preferrable because then I can build the latest rakudo 11:41
diakopter: what do you mean by 'prefix fail'?
FROGGS sisar: if you had ActivePerl and MSVC Express, you could build latest too
sisar: the dll is not in the right place 11:42
moritz that's the wrong approach
we need to fix rakudo to also build on cygwin
FROGGS moritz: true, but I wanted to offer something that would work right now 11:43
sisar FROGGS: are there instructions for that approach available anywhere ? 11:44
FROGGS sisar: in the README perhaps?
I think I've seen it somewhere
sisar also, the file INSTALL.txt in the rakudo repo needs to be updated to reflect recent changes 11:45
FROGGS but installing ActivePerl, Git, MSVC Express, and then configure + nmake it in the MSCV developer console should be all you need to do
moritz sisar: can you please do a grep PARROT_LIB_DIR Makfile|head -n1 and paste the result here?
sisar moritz: "grep: Makfile: No such file or directory" 11:47
moritz sisar: sorry, Makefile
sisar oh !
moritz: no output
moritz that is seriously weird 11:50
sisar: can you please put the entire Makefile somewhere where I can read it? 11:51
sisar ok
11:51 ivan`` left
FROGGS I'd suggest you would also compile parrot again... maybe it is build with another --prefix? 11:52
sisar: is that possible?
(the changed prefix I mean)
diakopter what about also incluing --gen-parrot
sisar diakopter: that fails in the same way 11:53
moritz: paste.ubuntu.com/6335309/
moritz that's all not helpful
the output shows for example /home/siddhant/rakudo/install/lib/parrot/5.9.0-devel/tools/build/pmc2c.pl
which shows that parrot has the correct prefix
FROGGS k
moritz oh my 11:54
FROGGS does that lack the parrot specific makefile snippets?
moritz yes 11:55
because npq-p failed to build
moritz has been looking at the wrong end
sisar: sorry, I need nqp/Makefile too 11:57

sisar: if that works, I know how to fix it
sisar moritz: "error:imcc:loadlib directive could not find library `nqp_bigint_ops' in file 'src/vm/parrot/stage0/NQPMO-s0.pir' line 1" 12:07
moritz sisar: but dynext/nqp_bigint_ops.dll exists, right?

moritz why does youtube has to end playing the current video when I start a new search? 13:49
PerlJam foolishness
moritz it could just move it to a corner, make it a bit smaller, and does the search with ajax in the main area
masak moritz: that's the way the iPad YouTube client works, fwiw. 13:50
mathw that would immediately lead to people saying "why does YouTube keep playing the video when I do a new search?" 13:51
moritz mathw: to which the obvious answer is "because you didn't stop the video"
mathw the obvious answer to your question is why not open a new window and search in that? :) 13:52
moritz because that's a hassle
masak YouTube as a whole is a hassle. it keeps asking me to provide my "real name". as if watching videos has anything to do with that at all. 13:56
moritz thinks of "masak" as a kind of valid "real name" 13:57

mathw I find it odd. Google integrate YouTube comments with their global identity system which is most manifest in the form of Google+ profiles. Half the reaction I see is "Google+ is a failure so obviously Google are trying to get higher user counts for it by the back door!" 14:07
not "I don't want to tie my YouTube activity to my Google+ account"
masak FROGGS: that's a lot fewer percents than last time.
mathw not privacy concerns
but worry about Google claiming Google+ is more successful than it is
very odd
masak I don't want to tie my YouTUbe activity to my Google+ account. I don't want a Google+ account. 14:08
mathw I think some people think that one day it might become more popular and they'll suddenly be forced to stop using Facebook.
14:08 rurban joined
masak well, I'd rather be in Google's silo than in Facebooks. but my first choice is neither of them. 14:09
mathw that's a viewpoint I can understand 14:10
I don't understand this apparent fear some people have of Google+ appearing to be anything more than an abject failure (which it isn't, but they like to pretend)
moritz well, facebook and google both have way too much private data of folks 14:11
imagine all that data in one hand
that's truly scary
14:13 Vendethi_ left
PerlJam ... and that's how skynet starts its attack. 14:14

masak PerlJam: Skynet seeding its first attack on social user accounts? now *that's* scary. 14:15

moritz does the JVM backend translate QAST straight to JVM bytecode? 21:02
or is there an intermediate format?

lizmat_ at one point, I was sure there was an intermediate step, but right now I'm not so sure 21:05
jnthn will know :-)
just found this in docs/deprecations:
Str.capitalize and &capitalize are deprecated in favor
of the the Str.wordcase and &wordcase routines.
They will uncondtionally warn in 2012.10, and be removed in 2012.11.

japhb__ jnthn: When you're thinking you could really use a break from threads, but are still in a hacking mood, ability to convert between (u)int32/64 and float/double on JVM is near and dear to me. :-) 23:33
japhb__ attempts to enqueue a job on jnthn.scheduler ... 23:34
23:34 zwut00 left
japhb__ Come to think of it, arnsholt would know how to do that too, I suspect. 23:34
23:35 PacoAir joined
jnthn japhb__: Where convert means "re-interpret bytes"? 23:35
japhb__ jnthn: exactly 23:36
The problem is that Protocol Buffers intrinsically see data on two levels: chunks of raw data of certain lengths, and typed data. When you read a field from the PB, you read a tag indicating field ID and a "wire type" that says how to calculate the length to read. 23:37
Then after that you read the raw bytes, and encode/decode the bytes as appropriate according to the field type you look up for that field ID. If you don't recognize the field ID (because you have an old copy of the message definition), you are required to pass the raw bytes through for other processing elsewhere. 23:39
The inverse occurs while going the other direction; dumb filters are supposed to be lossless, except for possibly rearranging fields on the wire for canonical packing. 23:40
So I've got code that sees a "64 bit" wire type, loads 8 bytes and turns them into a uint64, and passes them on to the code that tries to map a field type to determine whether to reinterpret as a double. 23:41
And I'm trying to do all this without creating and passing a ridiculous number of tiny blob8's around. 23:43
