AdemanxorAxAx: well in pypy.objspace.sliceobject.W_SliceObject there's a method indices4() which I think would be very useful as a free function (for use in conjunction with space.decode_index) and I was wondering where I should put it (i wouldn't remove it from W_SpaceObject obviously)00:29
xorAxAxyou want to duplicate code!?00:29
xorAxAxmove it somewhere into rlib00:29
AdemanxorAxAx: hah, don't implicate me!00:30
xorAxAxyou said you wouldnt remove it :-P00:30
Ademanmove the implementation to wherever then call it in W_SpaceObject.indices4 for compatibility, sheesh! :-p00:30
xorAxAxah, thats something entirely different, my bad!00:31

fijalAdeman: hm02:54
fijalprobably a helper on space would be the best place02:54
fijalAdeman: why you can't use a method on W_SliceObject?02:55
Ademanfijal: well, i thought decode_index was quite nifty, i'll show you what i'm currently doing02:56
fijalwould be good, yes :)02:56
fijalhow was improving the test coverage?02:56
fijalI can run coverage report for you if you like02:56
Ademanfijal: well i found some truly horrifying bugs while trying to fix regressions i created02:57
Ademanit looks like nonsquare matrices break multidimarrays now...02:58
fijalplease write test for each thing you do02:59
Alex_Gaynorpossibly even befor eyou do it :)02:59
Ademanfijal: so http://paste.pocoo.org/show/174456/ is sdarray.py  line 24 is the stolen W_SliceObject.indices4 code, and 174 is an example usage02:59
Ademanfijal: can you tell the other guy? it wasn't my code...03:00
fijalbasically I would like you to commit things one by one, each with test03:00
fijaldid the other guy's code break tests?03:01
Ademanno but it added new, insufficiently tested features (the nonsquare matrices thing is a new development)03:01
Ademani wrote a test that will catch it though03:01
Ademani'll try and avoid monilithic commits like i'll be doing soon... in the future03:02
fijalhow about doing it now?03:03
fijalthen revert it03:04
fijalbasically write a test and revert this with sufficient commit message03:04
fijal"this commit came with no tests and it's broken, see skipped test"03:04
fijalpersonally, I would like solid features first03:04
fijaland then new03:04
fijalAdeman: really, start avoiding monolithic commits just now03:05
Ademanyeah, although i'm excited to have a translatable implementation in the repository... and i've been busting my butt to do it too...03:05
fijaltake your working copy03:05
fijaland commit each feature you added by doing tedious diffing03:05
fijaleach one with a test03:05
fijalhow about that?03:05
Ademan:-/ fine03:05
fijalAdeman: I hope I'm not mean, I'm more trying to get you going with our development practices03:05
fijalwhich I think are superior :)03:06
Ademani understand, you're just frustrating sometimes :-p03:06
fijalsorry about that03:06
Ademanhahah i'm jk03:06
fijalI'm really trying to be nice :)03:06
Alex_Gaynoroh hey I started translating pypy earlier03:06
Alex_Gaynorforgot about that03:06
fijalI'm just not a nice person03:06
fijalAlex_Gaynor: takes a while, heh?03:07
Alex_Gaynorfijal: dunno, I svn up'd when I got back from class, started translating and then I worked for the rest of the afternoon.  I have one shell with many tabs and I forgot about it03:07
fijalAdeman: in exchange, I can review each commit, deal?03:08
Alex_Gaynorfijal: who do you work for?03:08
fijalAlex_Gaynor: merlinux, sometimes03:09
fijalwhy do you ask?03:09
Alex_Gaynorjust curious, you seem to have tons of time to work on pypy :)03:09
Alex_GaynorI figured either you have an awesome job, or very good time management skills03:09
fijalor I'm just very poor03:09
fijalor have rich parents03:10
Ademanfijal: haha only if you have time03:10
Alex_Gaynorfijal: it's not polite to ask those questions ;)03:10
Ademani wish i had more time03:10
fijalAlex_Gaynor: tbh, I don't even have a car03:10
Ademanfijal: so would it be acceptable if I added the test on top of the current HEAD ? rather than reverting and commiting it together with the test?03:11
raymondh (~chatzilla@cpe-75-82-47-224.socal.res.rr.com) joined #pypy.03:11
fijalAdeman: is current head broken?03:11
Ademanfijal: according to the tests i've written, i'm fairly certain03:12
Ademani'd need to try out my tests on a clean working copy03:12
Ademanto be sure03:12
fijalI would rather have no features than buggy features03:12
fijala revert then sounds fine03:12
fijalprovided that a commit message explains it correctly03:12
raymondhIf you guys see Laura in the chatroom today, please encourage her to run for the PSF board.  Today is the last day to self-nominate.03:13
Ademani haven't seen her for a long time...03:13
fijalraymondh: how about writing her a mail?03:14
fijalshe's probably sleeping, though you never know03:14
raymondhI wrote to her yesterday but didn't have a response yet.03:16
Ademanfijal: alright well i'll try out the test on a fresh working copy03:16
fijalraymondh: not sure what else we can do03:16
fijalraymondh: you can write to samuele pedroni, who is in direct contact03:16
fijalI'm in the US03:16
raymondhWill do.  Thx.03:17
gutworthI'd vote for her :)03:18
AdemanI'm sure there's a clean way to accomplish all this with svn, but staging commits from your working copy is one thing git does quite well03:19
Alex_GaynorIf I had a vote I'd vote for Tim Peters, he understands that python is too big to fail and that we need TARP money03:19

Electronic[sleepAdeman, hi.04:51
Electronic[sleepWhy indices4 is not suitable for you?04:52
Electronic[sleepBecause we need to check space.is_true(space.isinstance(w_index, space.w_slice)) ?04:53
Electronic[sleepAnd behaivour of decode_index...04:53
Electronic[sleepWhy do you check stop==0? If i want empty slice 0:0, what will you do?04:54
Electronic[sleepBTW have you done many new features? I've done operators for multidimensional arrays.04:55
Electronic[sleepIt may be time to merge.04:55
Nick change: Electronic[sleep -> ElectronicRU04:56
engla (~ulrik@wikipedia/Sverdrup) left irc: Ping timeout: 276 seconds05:01
AdemanElectronicRU: well most of what you did isn't valid rpython, including your handling of slices, so it has to change either way, decode_index is a nice way to accomplish it that IS RPython05:21
ElectronicRUindices4 is not rpython? It is used in listobject.py!05:24
ElectronicRUAnd afaik there is no task now to compile pypy. I won't compile anyway.05:25
Ademannot indices4, your entire slice implementation05:27
ElectronicRUcompute_slices() ?05:28
ElectronicRUOr creating new objects for storing slices?05:28
ElectronicRUOr what?05:28
Ademanwell first of all calling indices4 on a W_Root object05:29
ElectronicRUHmmm... Is there a way to explicitly typecast it to slice?05:34
ElectronicRUWell, we can use decode_index, but in 'if space.is_true(... w_slice)):'05:35
ElectronicRUBecause of 0:0 :)05:35
Ademanwell, if step is 0 it's an invalid slice anyways right? so testing step for 0 instead of stop would be correct05:40
fijalexplicit cast is an assert isinstance(x, W_SliceObject)05:49
fijalElectronicRU: 71014 came with no test05:50
fijalit's usually enough to revert without looking05:50
fijaldo you feel like writing tests for that checkin?05:50
Ademanfijal: so that'll down cast?05:51
Action: Ademan learned something05:51
Ademanthe annotator is interesting lol05:51
fijalthat'll let you call methods of W_SliceObject05:51
fijalElectronicRU: or at least test coverage is not enough05:52
ElectronicRUAll stuff I done I tested.05:53
ElectronicRUAlthough my blame is using square array for test.05:53
ElectronicRUAdeman, if x:0:0 we must raise; if x - return. If x:0:0 we will return self[x], which is not valid.05:54
Ademansquare is fine, but be sure to test nonsquare too, i was working on that but if you want to do it yourself you're welcome to05:54
pemryan (~pem@2001:cc0:201e:107:221:86ff:fe1a:e5aa) left irc: Read error: Connection reset by peer05:54
ElectronicRUfijal, thanks for explicit typecast. W_SliceObject is is the same place where W_Root?05:54
Ademanalso: fair enough, just do the explicit cast then05:55
fijalElectronicRU: can you run py.test -p figleaf and stare at generated html?05:56
fijalElectronicRU: obvious thing is that you added __rmul__ although no test exercises that05:57
ElectronicRUThere was use case for __radd__ (value+array) in test.05:57
ElectronicRUSo I've added all __r__'s.05:58
fijalis it tested?05:58
Ademani should also note that ufunc.py isn't rpython anymore (since a long time ago...) because arrays can now be different types05:58
ElectronicRUIt equicode with __*__'s.05:58
fijalin general (not blaming you particular) I'm not too happy about test coverage of micronumpy05:59
fijalAdeman: let's ignore being RPython for now05:59
ElectronicRUAdeman, No module named std.sliceobject05:59
ElectronicRUWhere is W_SliceObject05:59
fijalElectronicRU: in pypy/objspace/std/sliceobject.py05:59
ElectronicRUOh, i have written pypy.interpreter.06:00
Ademanfijal: we're so close to completely rpython though... :-/ but fine06:02
ElectronicRUSo, I'm going out. But ===WARNING=== could not import plugin 'pytest_figleaf', reason: "could not import 'figleaf.annotate_html'"06:02
fijalElectronicRU: install figleaf python package06:03
fijaluploaded coverage run06:04
fijal__setitem__ coverage is not good for example06:04
fijalanyone every iterates in test single dim array, or is this figleaf getting wrong data?06:04
Ademanfijal: well that looks like an old revision06:05
fijalElectronicRU, Ademan: in general, I'm not too happy about the coverage. I would like to improve this first before adding more features06:06
fijaland yes, I appreciate the work you're both doing, don't get me wrong :)06:07
AdemanElectronicRU: do you want to write the test for mdarray or do you want me to? it sounds like that's the first thing we need to do06:13
Ademani still need to update my version of py.test so that i can properly figleaf though...06:15

ElectronicRUfijal, does annotator takes in mind what conditions are in 'if'? I've thought that instead of checking space.isinstance and asserting isinstance I may just check isinstance(W_SLiceObject).11:10
ElectronicRU<mwhudson> Ademan: right, you can't define new functions at runtime11:11
ElectronicRUNested functions are unallowed too?11:11
antocuniElectronicRU: nested functions are fine, as long as you create them at translation time11:19
antocuniElectronicRU: and yes, the annotator know how to deal with "if isinstance(xxx)"11:20

magciusfijal, I'm asking where/how it translates file objects16:09
magciusOr where there's support for that in the interpreter.16:10
magciusIIRC files are very important to PyPy.16:10
fijalfor example cli has a directory called src16:10
fijalthere are external functions that are supported by cli16:10
magciusI didn't see anything file-related in there, but I'll check again16:11
magciusOh. I misspoke16:11
fijalthere is ll_os16:12
pedronisit's all a bit of a kludge because we assume file descriptors16:14
magciusyeah, I only see two references to it in the *.py files in the cli directory, neither of them apparently are related to loading the modul16:14
magciuswhich are rte.py and database.py16:14
fijalmagcius: you have to look at cli files16:14
fijalnot py files16:14

hpkfijal:  could you give the "slower" benchmarks a red rounding or so? 19:12
hpkand did you get to do the second version with pypy-c? 19:12
fijalcan you explain what means "red rounding"?19:13
fijalnope, didn't get to it19:13
hpki mean a red frame, instead of the grey one - or some other easy-to-detect marker that a benchmark is slower 19:13
hpki mean pypy-c-jit is slower than cpython19:13
hpkwell, maybe it's fine - i just look for the red "slower" i guess19:14
fijalI would say red slower is fine19:14
hpkcan you make the title be closer to its belonging box? 19:15
hpkthe titles are almost closer to the wrong box 19:15

fijalhpk: good :)19:24
magciusput margin: 0; in .smallcaption19:24
magciusyeah, that's what you did19:24
hpkfijal:  sorting by speed would also be nice, maybe - then the "red" issue just vanishes 19:24
hpki.e. have the slowest ones first or last 19:24
fijalhowever, I don't want order to swap19:25
fijalat random points in time19:25
fijalI'm happy with alphabetical order19:25
hpkwell, this would mean that pypy performance randomly swaps which would be interesting to notice, wouldn't it? :) 19:25
magciusfijal, mind making the td have a class "slower" when it's slower?19:25
fijalmagcius: why?19:26
hpkfijal:  i claim it's actually interesting information, the ordering by speed, whereas alphabetical is pointless 19:26
magciusfijal, you could make them have a background color for better visual stats.19:26

hpkfijal:  the legend is wrong, it still says pypy-c-jit 20:27
hpkso to begin with: AI gets twice as slow with the jIT 20:28
hpkno, wrong, sorry20:28
fijalAlex_Gaynor: I'm not sure yet what's the purpose20:28
fijalAlex_Gaynor: it's frustrating that perf.py does not support more than two interpreters20:29
Alex_Gaynorfijal: yes, would be nice for it to do more, no reason it can't though20:30
fijal"it's work" reason20:30
hpkfijal:  ok, so pypy-c-jit is faster than pypy-c everywhere - maybe it makes more sense to compare pypy-c against pypy-c-jit after all, that's at least what i was interested in 20:31
hpki guess that would be a trivial change 20:31
hpkunless mechanics make it hard :) 20:31
hpkand eventually pypy-c-jit against unladden swallow - such 3 different pages would cover the basic needs and interests IMO 20:33
Alex_Gaynorhpk: it should really only be one page though20:33
hpkyes, maybe - but mostly those are three different angles of comparing and if having more than 2 is difficult/too-much-work than i'd be fine with 3 pages 20:34
fijalhpk: except then we would need to nightly build US20:34
pedronisfijal: so we are marginally slower on spitfire and faster on spitfire_cstringio20:34
fijalor something20:34
fijalpedronis: yes20:35
fijalpedronis: I'm about to use stringbuilder a bit more in places20:35
hpkfijal:  sure, don't want to rush you - just i think that comparing pypy-c and pypy-c-jit makes more sense, is that easier to do? 20:36
Alex_Gaynorfijal: I'll work on a patch for perf.py to run multiple interpretters20:37
hpkhtml5lib is a high contender to flip from slower to faster :) 20:38
fijalhpk: as of now, it requires further fiddling in places which I don't like20:38

fijalhpk: http://codespeak.net/svn/pypy/benchmarks/20:44
fijalgutworth: because of resizable/unresizable list20:44
fijalwe don't have a cast between those20:45
fijalthe only way is to copy a list20:45
gutworthoh right20:45
fijalI know it's a bit stupid :-/20:45
fijalhowever the model is as it is right now20:45
gutworthsince unpack iterable already copies :(20:46
pedronisnot always20:46
fijalbut you don't know if it copied or not20:46
fijalpedronis: unpackiterable always copies I think20:46
pedronisbut fixedview has shortcuts no20:47
pedronisin the std space20:47
fijalpedronis: yes, but in case you do fixedview on a list20:47
fijalyou effectively get two copies20:47
fijal(I think)20:47
pedronisbecause there's a shortcut20:48
pedronisso you get only one20:48
pedronisjust wondering which fixedview gutworth is starting at20:48
fijalpedronis: ok20:48
fijalpedronis: but in case you have something else than a list, you get two copies20:48
fijal(say dict or set or something)20:49
fijalwell, in fact we should have a cast from resizable -> unresizable20:49
fijaland the other way around20:49
fijalwhich would be used here20:49
pedronisyou mean an explict op20:50
fijalwhich would have a trivial rtyping20:51
fijalone would simply dereference pointer20:51
fijalthe other would allocate a small wrapper around20:51
pedroniswell is not really a cast20:51
fijalbut there are places which could use that20:52
fijalgutworth: lists in rpython are a mess, unfortunately20:53
pedronisalso I'm confused20:54
pedronisthere is over allocation20:54
pedronisso you cannot simply read out the fixed list20:54
fijalok, so copying is the only way it seems20:55
nsfomg, just ported my hackerish C declaration parser (for documentation system) to pypy.. uses pygments and ply: http://jiss.convex.ru/cdecl.pypy (there is also .py version, uses CPython, see Version string on the page)20:55
nsfit works! :)20:55

fijalpypy 1.1.0 does not contain the jit20:56
gutworthat least we can congratulate ourselves for having good gcs :)20:57
