twb: You might want to print "use runghc Setup sdist" unless someone fixed cabal-install to actually call Setup for sdist. Otherwise, the tarball may be bogus, if it is created at all... |
| 05:55 |

(Ack, still broken with my 0.8.0...) |
| 07:02 |
|
twb |
Yeah, it was explained to me just now that "cabal sdist" and "runghc Setup sdist" actually do COMPLETLY DIFFERENT THINGS |
| 07:07 |
|
mornfall |
Yes. Bummer. |

do you know if there are tools for exploiting .prof files? searching through them is a bit of a pain |

I think one of the lessons in my fantasy Haskell performance book is "how to look at a profile", giving lots of examples and showing the kinds of things your eyes should be landing on, and why |
| 10:16 |
|
kowey |
(although that's not very related to your question) |
| 10:17 |
|
gal_bolle |
well it would be the following question |
| 10:19 |
|
kowey |
http://book.realworldhaskell.o[…]optimization.html sorta does it, but I'm still a bit too tl;dr-ish for it (which is unfortunate) |
| 10:19 |
|
kowey |
what I would want to see is a profile, with segments of it highlighted (circled in a red pen) |
| 10:20 |
|
kowey |
and little arrows pointing from one circled bit to another - sort of a "how your eyes *ought* to be scanning this page" |
| 10:20 |
|
gal_bolle |
rwh is a bit light on time profiles |
| 10:20 |
|
kowey |
(the other thing in my fantasy book is lots and lots and lots of case studies) |
| 10:21 |
|
kowey |
basically each chapter being a case study focusing on a particular kind of pathalogical behaviour and maybe also lots of mistaken attempts at making things go faster |
| 10:23 |

hi |
| 11:36 |
|
gypsymauro |
there is a way to add all new files to a repository? |
| 11:37 |
|
gypsymauro |
I can find them with darcs what -ls |
| 11:42 |
|
kowey |
hello! I think you're looking for darcs add -r |
| 11:42 |
|
kowey |
but if you're repository is large, watch out for http://bugs.darcs.net/issue80 :-( |
| 11:45 |
|
gypsymauro |
kowey: I think I've got a mess, if I try to add the folder it says: |
| 11:45 |
|
gypsymauro |
The following files and directories are already in the repository: |
| 11:46 |
|
gypsymauro |
and a list of file |
| 11:46 |
|
gypsymauro |
and at the end |
| 11:46 |
|
gypsymauro |
darcs failed: No files were added |
| 11:46 |
|
kowey |
that sounds fairly normal; darcs just reminds you if you've already added the files |
| 11:46 |
|
gypsymauro |
can I remove them in a step? |
| 11:46 |
|
gypsymauro |
it's a css folder |
| 11:46 |
|
kowey |
the new darcs 2.4 has darcs remove -r |
| 11:47 |
|
gypsymauro |
darcs remove css fails |
| 11:47 |
|
gypsymauro |
oh |
| 11:47 |
|
kowey |
but it's in beta - cabal update; cabal install darcs-beta if you have the Haskell Platform and are willing to help use test |
| 11:47 |

I believe http://wiki.darcs.net/FrequentlyAskedQuestions may have an answer for you, but I don't remember |
| 11:48 |
|
kowey |
(i.e. one trick that doesn't involve upgrading Darcs just yet) |
| 11:48 |
|
gypsymauro |
how can I know what I neet to delete befor trying the add again? |
| 11:49 |
|
kowey |
ah, here we are: http://wiki.darcs.net/HintsAnd[…]versions-of-darcs |
| 11:49 |
|
kowey |
actually: allow me to probe that question a little bit |
| 11:50 |
|
kowey |
why bother deleting and adding them again? |
| 11:50 |
|
kowey |
is it because you think you've added too much and want to step back a little? |
| 11:50 |
|
kowey |
you can do darcs whatsnew -s to see what you've added |
| 11:51 |
|
kowey |
OR if you just want to record your changes in smaller bits and pieces, you could just do darcs record and then interactively select 'n' on the bits you don't want to record yet |
| 11:52 |
|
gypsymauro |
damn it fails |
| 11:52 |
|
gypsymauro |
I tried the xarg line |
| 11:52 |
|
gypsymauro |
but if dails |
| 11:52 |
|
gypsymauro |
kowey: just cause it fails for case names |
| 11:53 |
|
gypsymauro |
and now I can't delete nor add them again :( |
| 11:53 |
|

gypsymauro |
I'm lost |
| 11:53 |

| 11:53 |

if I try to add again them it fails |
| 11:53 |

files that differ only in case. Use --case-ok to override this: |
| 11:54 |
|
gypsymauro |
with darcs add -r css |
| 11:54 |
|
gypsymauro |
and then |
| 11:54 |
|
gypsymauro |
darcs add -r --case-ok css |
| 11:54 |
|
gypsymauro |
The following files and directories are already in the repository: |
| 11:54 |
|
gypsymauro |
a lot of file and then |
| 11:54 |
|
gypsymauro |
darcs failed: No files were added |
| 11:58 |

sorry, I was away for a bit |
| 11:59 |
|
kowey |
OK hang on... what operating system are you on, please? |
| 12:00 |
|
kowey |
I'm just curious... I'll bet you're on some variant on Linux just because you're using a case-sensitive filesystem |
| 12:00 |
|
kowey |
(or appear to be, in that you have different filenames that differ by case only; or maybe I'm wrong) |
| 12:01 |
|
kowey |
here's a pastebin you can use if you'd like to plug your commands and error messages into them - http://pastebin.ca/ |
| 12:03 |
|
gypsymauro |
sorry I've to leave maybe we will check later, tank you a lot for your help :) |
| 12:04 |
|
kowey |
hmm: I wonder how we could have helped with that user experience |
| 12:05 |
|
kowey |
interesting observation here is that we've got a case of user inferring that something is "wrong" when really from our point of view, things are perfectly "OK" |
| 12:05 |
|
kowey |
in the sense that darcs add "fails" to re-add the user's file |
| 12:06 |
|
kowey |
... which we think of as a good thing because it's good to know you've already added them, but which the user here perceives as "argh, scary!" |

mornfall: OK, so web interface problem... hmm, I'll have to think about this |
| 16:13 |
|
kowey |
proxy server? browser cache? |
| 16:16 |
|
kowey |
lispy: complex answer. I think it just means "disk format". Traditionally "chunky hunks" just refers to the fact of coalescing the hunks into a single region |
| 16:16 |
|
kowey |
lispy: droundy tried to implement both changing the disk format and the internal representation, but ran into bugs |
| 16:16 |
|
kowey |
so (on the phone), he suggested backing off into just changing the disk format |
| 16:16 |
|
lispy |
kowey: ah yeah. I'd like to be more incremental in that regard. |
| 16:17 |
|
lispy |
My HunkHandles still use the same representation for Hunks |
| 16:17 |
|
kowey |
later on, mornfall in his blog post introduced a 3rd idea of storing the chunk on disk and referring to it as a hash |
| 16:17 |
|
kowey |
so I was wondering if HunkHandle was related to this third idea |
| 16:18 |
|
lispy |
kowey: did my ticket update clarify what a HunkHandle is? I think I sent in my patches and a description at one point |
| 16:18 |
|
kowey |
I'm trying to digest it |
| 16:18 |
|
lispy |
kowey: http://lists.osuosl.org/piperm[…]nuary/022760.html |
| 16:18 |
|
lispy |
that email is way more concrete |
| 16:18 |
|
kowey |
I regret that I never really got a chance to understand what this work was about :-( |
| 16:19 |
|
lispy |
It's simple |
| 16:19 |
|
lispy |
Dead simple |
| 16:19 |
|
lispy |
Do a pass over the patch bundle |
| 16:19 |
|
kowey |
sounds like a temporary cache of the hunk for processing |
| 16:19 |
|
lispy |
If you find a Hunk, record where it was in the stream |
| 16:20 |
|
kowey |
well, not so much a cache, but just a way of dumping to disk so you're not keeping in memory, anti-cache |
| 16:20 |
|
lispy |
(but don't load the hunk) |
| 16:20 |
|
lispy |
Later, when you need to hunk use readHunkHandle :: HunkHandle -> IO Hunk, to get the hunk |
| 16:20 |
|
kowey |
where it was in the stream, meaning its offset in the file? |
| 16:20 |
|
lispy |
yup |
| 16:20 |
|
lispy |
dead simple |
| 16:21 |
|
kowey |
ok, so if I understand correctly, what you're trying to achieve is to make it so that Darcs only keeps offsets in memory |
| 16:21 |
|
kowey |
because that's all it needs for hunk-hunk commutation |
| 16:21 |
|
lispy |
Bingo |
| 16:21 |
|
lispy |
Well |
| 16:21 |
|
lispy |
No |
| 16:21 |
|
kowey |
and in the rare case where you do need the hunk contents (eg. hunk-replace) you read them from disk |
| 16:21 |
|
lispy |
commute will not change (at least initially) |
| 16:21 |
|
kowey |
oh... |
| 16:22 |
|
lispy |
Later, it should be possible to apply Mornfall's ideas |
| 16:22 |
|
lispy |
So that we can do what you just suggested |
| 16:22 |
|
lispy |
But, first things first |
| 16:22 |
|
kowey |
wait, what did I suggest? |
| 16:22 |
|
lispy |
You suggested the "3rd" idea again |
| 16:22 |
|
lispy |
using hunk meta data to do commutes |
| 16:23 |
|
kowey |
OK, I think I can see structurally that there is a "4th" idea |
| 16:23 |
|
kowey |
but it's going to take me some more walking through before I can understand the distinction between the 3rd and 4th idea |
| 16:24 |
|
lispy |
Kind of. But, I see it as a prefactor to the 3rd idea :) |
| 16:24 |
|
kowey |
I mean, in my way of talking about it, I didn't really see it as "commutation changing" |
| 16:24 |
|
kowey |
because I thought it was just a fundamental reality that commutation does not affect the hunk contents during hunk-hunk commutation |
| 16:25 |
|
kowey |
so I guess I'm confused by why doing the 4th thing doesn't mean you get the 3rd thing for free |
| 16:25 |
|
lispy |
I'm talking about code that has to be changed |
| 16:26 |
|
kowey |
oh, so you're saying that to implement the 3rd idea, the commutation code necessarily has to change |
| 16:26 |
|
lispy |
commute won't show up in any of my diffs, I don't think |
| 16:26 |
|
lispy |
Yeah, I think so |
| 16:26 |
|
kowey |
(ah because it involves changing the internal representation of hunks to talk about hashes) |
| 16:26 |
|
lispy |
Yeah |
| 16:26 |
|
kowey |
OK, that's *starting* to make sense |
| 16:27 |
|
kowey |
and your hunkhandle work is completely orthogonal to the 1st (in-memory representation) and 2nd ideas (on-disk representation) |
| 16:27 |
|
kowey |
#2 I can see quite clearly |
| 16:27 |
|
lispy |
I do change the internal rep slightly |
| 16:27 |
|
lispy |
Now a PatchSet doesn't have Hunks in it, it has HunkHandles |
| 16:27 |
|
lispy |
and things that actually look at the Hunks will need to request them from disk |
| 16:28 |
|
lispy |
But otherwise, it's the same |
| 16:28 |
|
lispy |
(same as what we have now) |
| 16:28 |
|
kowey |
oh wait, is the reason why you think of #4 as being separate from #1 |
| 16:28 |
|
kowey |
that you still use hcOld :: ![B.ByteString] |
| 16:28 |
|
lispy |
Yeah |
| 16:28 |
|
kowey |
whereas #1 would mean using hcOld :: !B.ByteString? |
| 16:28 |
|
lispy |
Right |
| 16:29 |
|
kowey |
OK! thank-you! |
| 16:29 |
|
lispy |
you're welcome |

I wonder what happened to kolibrie's darcs record in http://wiki.darcs.net/Benchmarks |
| 17:16 |
|
lispy |
kowey: are those old benchmarks? I can't tell what version 2.3.99 is |
| 17:16 |
|
kowey |
those are the darcs 2.4 beta |
| 17:16 |
|
kowey |
it's just using our hackage-friendly versioning scheme |
| 17:17 |
|
lispy |
:( |
| 17:17 |
|
lispy |
Do you know which beta though? |
| 17:18 |
|
* lispy |
really dislikes the duplicity |
| 17:18 |
|
kowey |
perhaps darcs-benchmark should be a little evil and systematically replace N.99.C with N+1 rc C |
| 17:18 |
|
lispy |
Can we stop calling them darcs 2.4 betas and start calling them darcs 2.3.99? |
| 17:18 |
|
kowey |
I'm not entirely sure about which beta it is - I think folks just followed my requests |
| 17:18 |
|
kowey |
I still think the best thing to do is to flip to the odd/even scheme next time |
| 17:18 |
|
lispy |
My poor little brain just can't be trouble to store so many assosciative data structures |
| 17:19 |
|
kowey |
so that those versions would just be darcs 2.4 and darcs 2.5 respectively |
| 17:19 |
|
kowey |
and when it becomes stable, darcs 2.6 |
| 17:19 |
|
kowey |
easy to understand, no tricks |
| 17:52 |
|
|
kpreid_ joined #darcs |

kowey |
lispy: I think my point is that this will indirectly eliminate the need for duplication |
| 18:15 |
|
kowey |
I think we tend to talk about darcs 2.4 beta X instead of darcs 2.3.98 X because the latter sounds too much like darcs 2.3 |
| 18:15 |
|
lispy |
Well, if beta/alpha/RC is our natural language then we should use it and fix cabal :) |
| 18:15 |
|
kowey |
by giving us a distinct version number that does not sound like the previous one (darcs 2.5 vs darcs 2.4), we will be less likely to need to use two names |
| 18:16 |
|
kowey |
so what I'm saying is that having darcs 2.5.x means that we'll be less likely to want to call it darcs 2.6 beta |
| 18:16 |
|
kowey |
see what I mean? |
| 18:16 |
|
lispy |
If we abolish the beta/alpha/RC terminology and stick to numbers I'm okay too. I just want: One source version, one version number/name. |
| 18:17 |
|
lispy |
My brain is too small to do the duplicity thing |
| 18:17 |
|
kowey |
right... so what I'm proposing is a way of making it comfortable to stick to numbers |
| 18:17 |
|
kowey |
because right now, if you say darcs 2.4.1 and darcs 2.4.99.1 in the same sentence, *my* brain gets confused and thinks you're still talking about darcs 2.4 |
| 18:18 |
|
kowey |
so if we adopt the hybrid scheme, hopefully we're both happy - no duplication for you, and no accidentally-thinking-theyre-the-same for me |
| 18:18 |
|

In your email you still called 2.5.x the 2.6 beta |
| 18:20 |
|
lispy |
So I would want to stop doing that |
| 18:20 |
|
lispy |
Either stick with 2.6 beta or with 2.5.x |
| 18:20 |
|
kowey |
fine! |
| 18:20 |
|
kowey |
I'm using the old terminology to bridge to the new terminology |
| 18:21 |
|
lispy |
ah |
| 18:21 |
|
kowey |
I don't think you'll be able to stop people from saying 2.6 beta informally, but I think that will just wither away on its own, because it's just easier to say darcs 2.5.x to mean darcs 2.5.x |
| 18:21 |
|
lispy |
That was not clear |
| 18:22 |
|
lispy |
Cabal should probably have support for release candidates and/or hackage may need a sense of 'unstable' like the more mature distribution systems (see Debian/Ubuntu) |
| 18:22 |
|
lispy |
But...That's a lot to change |
| 18:22 |
|
lispy |
And there seems to be resistance |
| 18:23 |
|
kowey |
so this is an easy way forward, and it's a common one in the FOSS world |
| 18:23 |
|
lispy |
I've never noticed the .99 stuff before, but odd/even is common yeah |
| 18:23 |
|
kowey |
no, the .99 stuff is ours |
| 18:24 |
|
lispy |
I've never cared much about version numbers. I just want it to be easy to know when you have same or different versions :) |
| 18:24 |
|
kowey |
because we're one of the rarer projects that are (a) big enough to need a multi-stage release procedure and (b) use hackage |

How come? |
| 20:17 |
|
Heffalump |
no idea why |
| 20:17 |
|
Heffalump |
they just sent me an email saying "we've cancelled it, here are your options" |
| 20:17 |

Heffalump |
well, the travel options to/from the airport were pretty nasty and I was beginning to wonder if I shouldn't have done something else anyway, so it might not be too bad |
| 20:18 |
|
Heffalump |
but now I need to investigate the options |
| 20:20 |
|
Heffalump |
gah, bastards: |

options being "Get a refund" and "A free transfer", where there's no indication of what the options might be for the free transfer. |

oof, I think I finally have a version of darcs-benchmark that takes repo variants into acct |
| 23:33 |
|
kowey |
although there is a significant risk I'm displaying the tables completely wrong, thereby making the results totally wrong... |
| 23:45 |
|
Heffalump |
cool |

Easyjet cancelled my outward flight, btw. |
| 23:46 |
|
kowey |
:-( |
| 23:47 |
|
kowey |
hmm... yeah I noticed in the log |
| 23:47 |
|
kowey |
hopefully they'll have more info soon. that's weird |
| 23:48 |
|
Heffalump |
was mainly wanting to warn you about yours, but since it seems to still be offered (whereas mine isn't) I guess it's ok |
| 23:49 |
|
Heffalump |
I think I can pay about £60 more and go with Swiss at somewhat nicer times, anyway. |
| 23:49 |
|
kowey |
probably worth it in fatigue-avoidance terms |
| 23:50 |
|
Heffalump |
yeah, I'd already been vaguely wondering to myself if I'd made a good choice with Easyjet, so I'm not too fussed |
| 23:53 |
|
Heffalump |
given the continuing noise about performance regressions, I'm starting to think skipping 2.4 might make sense |
| 23:54 |
|

Petr does seem to think that it's an unlikely corner case, the last bit of news |
| 23:54 |
|
Heffalump |
the Haskell-Cafe report? |
| 23:55 |
|
kowey |
uh-oh, I must have missed something recent then |
| 23:55 |
|
kowey |
I really need to get back into reading that list |
| 23:55 |

Ben Franksen on Haskell-Cafe |

very recent thread |
| 23:56 |
|
* kowey |
reads |
| 23:56 |
|
Heffalump |
(what corner case are you referring to?) |
| 23:57 |
|
kowey |
argh... I didn't really get a chance to understand the thread, but it's worth holding off on this |
| 23:58 |
|
kowey |
this corner case: http://bugs.darcs.net/issue1746 |
| 23:59 |
|
Heffalump |
oh, and while reviewing Petr's latest stuff I found a really egregious bug in darcs, which I'm a bit surprised hasn't been found before (at least, I couldn't spot a test case for it) |
| 23:59 |
|
kowey |
oh good |
| 23:59 |
|
Heffalump |
basically darcs add dir ; darcs add dir/file ; darcs rec ; darcs remove dir ; darcs rec ; darcs oblit <last patch> ; darcs check fails |
| 23:59 |
|
kowey |
oh wow |
