04:59:19JdGordonamayer: what are your plans for the theme site? if you just want to do fixups then i think we should go about getting you commit access
04:59:43JdGordonif its more then you really should just fork it, put up your finished site and them switch
04:59:48amayerJdGordon: im game for that
05:00
05:00:07amayeri am confused about the forking tho
05:00:16amayerfor now its just minor things here and there
05:00:34amayerim not like rebuilding the way it works just making it more efficent

05:01:53amayer*totaly confused*
05:01:55amayerthat is all in the master branch
05:02:36amayerJdGordon: i already do that. not a public server but i have a dedicated box(ok its a laptop) just for the theme site

11:43:54kugelalso don't change too much in one go, incremental changes are better
11:44:23[Saint]most of it is purely cosmetic code changes
11:44:48[Saint]and the rest is just making the various cabbies more similar with each other
11:45:24[Saint]there's some weird, completely unnecessary, differentiation between some of the cabbie ports that I'm ironing out.

11:54:13[Saint]Anyway, yeah. I haven't actually changed the layout of any of the cabbies at all. I've just unified the metadata between the ports, and made the different ports code as similar to each other as possible.
11:54:40[Saint]and updated old syntax to new syntax in a few places.
11:55:32[Saint]But, yeah...it's pretty much all "behind the scenes" cosmetic stuff that I hope will make cabbie a better teaching tool.

12:02:50pixelmaI always wanted to have the c200 version use a 10 pixel font instead of 11 so that on the WPS there could be one more row and hence having space for the playing time info line all the other ports have. Since using my own WPS on the c200 though, motivation wasn't very high
12:03:29wodzamiconn: ping
12:06:54[Saint]pixelma: does a suitable 10px font exist?
12:07:34[Saint]I have made a set of anti-aliased fonts from GNU Unifont that I was considering useng.
12:07:38pixelmait's currently using 11-Sazanami-Mincho and we also have a 10-pix version of that
12:08:23[Saint]although the aa fonts are large (and GNU Unifont is ugly) I think that the default theme that Rockbox ships with should "just work" for any language.

12:11:21Torneif you somehow get hold of a 2TB card and it doesnt' work in rockbox that's a bug and if you let us know we can probably fix it :p
12:11:21xvatOF = original firmware
12:11:38xvatI haven't thought of using more than one firmware, i was set on using only rockbox

12:13:02[Saint]Subscription/paid content, is one that I can think of.
12:13:12Torneuntil someone actually makes a kind of SD card that isn't physically/electrically backward compatible it will work if we implement the code right :)
12:13:15[Saint](wrt: reasons to use the OF)

12:14:39[Saint]that was non-obvious to third parties though, apologies.
12:14:51xvat[Saint]: ah, afaik Sansa Clip+ has none of that
12:14:53Tornethat doesn't make sense, though
12:15:29Tornethere's no actual reason why you couldn't make an SD card that was a trillion terabytes, or whatever, and still have it be compatible with existing reader hardware :p
12:15:38Torneyou'd need to invent a pretty entertaining variant on the SD interface spec..
12:15:42Torneand write some funky drivers :p
12:15:53Torneand you might not be very happy with the performance.
12:17:03wodzwho cares about performance when handing trillion terabytes SD :-)

12:21:31Tornewhat's limiting about them?
12:21:53Tornesomething made in huge volume by a consumer manufacturer is going to be cheaper and better-built than anything we can arrange to ahve made
12:22:19Tornethere isn't really anything rockbox can do that current players have a problem with
12:22:23Torneso, what's the point? :)
12:22:29xvatalright
12:22:32[Saint]It's just way cheaper to work with existing hardware, and most of the time these players have more than enough "guts" to play damn near anything (even foolish audiophile quality audio).
12:22:34wodzfor open hardware DAP project there are two limiting factors 1) cost 2) mounting technology will most users can't handle

12:29:43Tornethe jack is fine in mine
12:29:56Tornei don't leave the headphones plugged in when i throw it in somewhere
12:30:07Torneso, there's rarely any forces applied to the socket.
12:30:13Tornei can see that breaking it maybe?
12:30:47Tornewhen i'm using it nothing is likely to happen that pushes on the headphone plug enough to do any damage
12:30:56Torneand when i'm not using it nothing is plugged in, so the socket can't really get broken

12:35:31wodzmortalis: I was thinking about cache problem and I see one race condition in previous code. If interrupt fires during cache invalidation it may go nuts
12:35:46wodzmaybe thats the reason of the problems

12:37:54Tornethere's a way for interrupts to happen during our cache invalidation?
12:37:57Tornethat would be bad, yes :)
12:38:49mortaliswodz: I have the same thought after I saw g339
12:38:51fs-bluebot3Gerrit review #339 at http://gerrit.rockbox.org/r/339 : Fix FS #12391 : Memory corruption on PP502x after commit_discard_idcache() by Boris Gjenero (changes/39/339/1)
12:38:57wodzTorne: in rk27xx cache controller is peripheral like anything else.
12:39:12wodzmortalis: heh, exactly the same here
12:40:04Tornewodz: right, then you need to disable interrupts while you wait for it, or else prove that no interrupt handler can ever touch the cachelines you care about :p
12:40:43wodzor disable caching
12:41:09Tornedepends on the semantics of disabling the cache
12:41:27wodzI mean disable cache; invalidate; enable cache
12:41:46Torneright, but that doesn't actually work on all cache implementations :)
12:42:08Torneit's possible you still read from cache while it's disabled
12:42:14Tornejust, no linefill operations take place
12:42:19Torneor other weird semantics :/
12:42:39Tornemost arches are not designed to ever have their cache turned off again for anything other than preparation for a reset/chainload of different binary/etc
12:42:46Torneso sometimes the behaviour is weird
12:43:09wodzSo you mean that it is actually safer to disable interrupts in wait loop of invalidate?
12:43:23Torneyes, that's what i'd suggest
12:43:40Tornealso, even if disabling the cache works for an invalidate, it doesn't for a clean
12:44:24wodzrk27xx cache doesn't distinguish this two - it has one commit and invalidate opcode AFAIK
12:44:37Tornethen you absolutely can't disable the cache to do it
12:44:44Nux|VomicaHi, i have a question about the compatibility of Rockbox with external media players over usb; In detail, its my Denon AV-Receiver, that has an USB Port where music can be played from USB Devices. It runs well with standard thumb drives, but for some reason cannot detect my IPod Mini 2g with Rockbox on it. Is there any way I could enable this? (The Denon also has a direct ipod control feature, but since I dont use the IPod defa
12:44:44Nux|Vomicault firmware, this feature is useless anyway.)
12:44:47Tornebecause anything that touches a dirty cacheline while it was disabled may read the stale data from ram
12:44:51Torneinstead of the current data from teh cache :)
12:44:54Torneso, yeah, disable interrupts.
12:45:12wodzTorne: ok, thanks for clarification
12:45:24wodzmortalis: could you test this on hifiman?
12:45:39TorneNux|Vomica: this usually happens because it recognises that it's an ipod by the USB vendor/product ID and then tries to communicate with it using the ipod accessory protocol, or to read the itunes database, or something else we don't undertand
12:45:40Nux|VomicaI read a bit about it, this might come from the "unformatted" 39.22MB part at the beginning of my IPods drive; or it might be that the denon is just not able to detect partitions other than the first one.
12:45:50TorneNux|Vomica: that;s unlikely.
12:46:10Torneyou will probably find if you patch rockbox to claim a different USB vendor/product that's not an ipod it will just work
12:46:18Tornebecause it'll treat it like any old usb device
12:46:24mortaliswodz: sure
12:46:45Tornewe've had this come up a bunch of times before; someone should really work out a nice way to solve this with an option :/
12:47:04Tornebut we don't have a usb id of our own to use.
12:47:47wodzhas anyone get in touch with openmoko to get vids:pids for our own?
12:47:49Tornewodz: hah, in fact yes, this means you can never disable the cache without having first disabled interrupts and cleaned the whole thing anyway :)
12:47:58Tornewodz: so yeah.
12:48:19Tornei don't think anyone has, no
12:48:33wodzI guess this would be the first step
12:48:42wodzsetting bit is easy

13:11:32Torneit depends how that's implemented
13:11:43Torneis the underlying cache op "invalidate by address"?
13:11:52wodzyes
13:11:54Torneand you just call it once for each cache line in the range
13:11:59wodzyes
13:12:25Torneif you can prove that interrupt handlers will never touch any of the cache lines you are invalidating, then it's fine

13:42:02wodzdid you rebuilt simulator or just changed the file?
13:42:49michaelrI downloaded a new one. I also did "../tools/configure" and then make and then make zip and used that zip

14:54:51Tornethe code is pretty bad in general already; bad db usage :/
14:55:40amayeri was talking about the theme class. but i found your comments.
14:55:50Torneso probably you arent really making it worse from that pov
14:56:26Torneif you actually want to work on the therme site you may want to look at fixing the db stuff though.
14:56:40amayeras far as the db class goes i was just updating it so it would work on my server... i dont think i want to rewrite the whole thing right now(maybe in the near future)
14:57:01Tornenot the db class
14:57:14Tornethe entire approach to queries
14:57:20Tornesprintf is a terrible way to do it
14:58:17amayeri was just using the same stuff that was already being used(trying to follow the same style)
14:58:20amayeri kinda get what it does but ive never used that sprintf function before
14:58:43Tornethe specific function isn't important
14:58:49Torneusing string manupulation to build queries is just wrong
14:59:02Torneregardless of how you manipulate strings
15:00
15:01:43Tornemichaelr: thanks for looking, but "works on target" is something you would only set if you have actually tested the code in question
15:03:23Torne"target" refers to a rockbox target, which is not entirely appropraite as a review category for the themesite :)
15:03:30Tornejust for reference
15:04:44amayerTorne: i will make the changes that you commented inline and resubmit over my lunch break(about 2 hours from now)
15:04:52Tornesure
15:05:14Tornebut seriously, if you actually want to work on the themesite code in general that would be great
15:05:31Tornebut you need to approach it from the perspective that what we have now is kinda actively bad and probably has all kinds of sql injection holes in it
15:05:36Torneand understand how to avoid this :)
15:06:37amayeri would like to work on the rockbox code. i have alot of ideas i would like to try and implement. ive never worked on something like this and it seems like alot of code to read before jumping in.

15:18:10Tornesure, the -1 is largely directed at things like spelling
15:18:22Tornei'm not expecting you to actually replace all teh db code with parameterised queries
15:18:29Tornejust, do the best you reasonably can :)
15:18:48Tornebut if you want a *next* project then replacing all the db code with parameterised queries would be pretty rad

17:41:38soapWe need to do something about the fact Rockbox Experts have the power to delete spam messages, but not ban the spammer.

18:31:48mortalisTorne, wodz: Speaking about invalidating cache range. I guess there is no guarantee that interrupt handlers doesn't touch cache lines we are invalidating, right?
18:46:19 Join derk0pf [0] (~k@p5DDC1CE1.dip.t-dialin.net)
18:50:23Tornein general, no
18:50:26Torneit depends what you are invalidating
18:50:30Torneand why.
18:50:52TorneFor a lot of cases in an OS it's possible to know that a given cacheline cannot be touched by any code right now
18:51:09Tornebecause, say, you know that the only references to that range of memory are in your local callstack where you are doing the invalidation
18:51:21Torneand this can help you do cache operations without blocking other things from running
18:51:27Tornebut in the general case, you can't always prove it

18:53:44yxothen i try to turn it on and OF don't start
18:53:47Tornethe "unbrick" process is to recover from the firmware being corrupted
18:53:56Tornephysical damage is basically never going to do anything to the firmware
18:54:01Torneso, i expect your hardare is just broken
18:54:10Tornesorry

18:54:57bertrikhave you tried starting it with the left/previous button pressed (should boot into the OF)
18:55:19yxono i go to recovery mode, i can write firmware i can read firmware from play it identical. but player do not start
18:55:55yxoi think that hardware is oko
18:56:27yxoi think that it's a logical only trouble
18:56:44Torneif it doesn't boot after writing a new firmware image to it in recovery mode and you're sure you did it correctly then no, the hardware isn't ok :)
18:56:51Tornepretty much by definition
18:56:58saratogawasn't there some trick where you could zero a few bytes when you write the firmware to get it to boot?
18:57:34yxobut when i go next time to recovery mode and read dump - dump is ok.

20:07:52amayerim looking for a more efficent way to work on the theme site. ive never worked on more then one patch at a time before
20:09:08 Quit Topy (Quit: Leaving)
20:13:27bluebrotheramayer: you can setup a repository somewhere else (like github) and push there.
20:13:59amayeri dont think im explaining this right
20:14:27bluebrotherok, then you might want to rephrase your question ;-)
20:15:10amayerlets say i want to work on file1 and make changes
20:15:13amayerat the same time i want to work on file 2 and make changes
20:15:14amayerthey are for seperate commits.
20:15:16amayerif i commit file1 and then commit file2 i can no longer make ammends to file1
20:15:19amayerhow do you handle work like this?
20:15:36bluebrotherdo you really need to amend the commit to file1?
20:16:06Bagderyou ammend commits, not files...
20:16:48Bagderwith rebase -i you can ammend earlier commits too, or you can cherry-pick etc into a new branch
20:18:12bluebrotherwhat I don't understand is why you (seem to) need to amend commits often. Amending is something you should need rarely.
20:18:28bluebrotherthe only exception are gerrit reviews.
20:18:43amayerim talking about gerrit reviews
20:18:57bluebrotheryou can also use different branches for this
20:19:09amayer...thats what i asked in the first question
20:19:27bluebrothernot exactly :)
20:19:43bluebrotheryou asked about pushing to different branches. You want branches. I.e. local ones
20:19:53 Quit Gallomimia (Quit: Gallomimia)
20:20:02bluebrotherall of those branches push to refs/for/master, so they end up as gerrit review
20:22:59amayerok. so i can have multiple local branches and gerrit will move them to the correct spot to be merged with the master of what ever project i am working on?
20:23:58bluebrothergerrit recognizes existing reviews using the Commit-Id line. Otherwise pushing an amended commit wouldn't work.
20:24:26bluebrotherit doesn't know about your local branches −− you're just pushing some commit(s).
20:25:04bluebrotherand since a commit on a local branch b has a different Commit-Id than a commit on branch a (unless you cherry-picked from b) it will create a new review.
20:25:23bluebrotheror update a different review if it's already existing
20:25:58bluebrotherhowever, if you're working on multiple things it might be easier to simply create a repository on github or similar and push to that.
20:27:07bluebrotherand then nag people to look at your patch series. Gerrit makes a review out of each commit which might not be the best thing in such a situation.
20:27:37bluebrother(and if you say made 7 commits you can still push the patch series to gerrit, which will then create 7 reviews)

20:34:32AlexP_e.g. banning people
20:34:34Torneit's much better not to make new changes, though
20:34:44Torneyou could've just uploaded a new patch to the old one
20:34:57Tornemaking new ones and abandoning the old ones means nobody who was watching the old one knows about the new one
20:35:09amayeri overwrote it with different files
20:35:19Tornethat doesn't matter
20:35:22amayerthats why i was asking about branches
20:35:23Torneupload a third patch that makes it right again
20:35:53bluebrotherTorne: hmm? Pushing stuff to github doesn't make it more problematic to create gerrit reviews. And given the slow reaction on gerrit reviews I had the impression it slowed amayer down.
20:35:55Tornealso, your db class change patch was fine and you could've just committed it
20:36:12amayerlet me explain the context
20:36:14Tornebluebrother: nobody was interested in looking at ameyer's changes at all
20:36:21Torneit's nothting to do with it being on gerrit
20:36:31Torneit's weird php hacking in the ugly themesite code
20:36:35Tornewhich most people are not interested in :)
20:36:45amayeri made changes to themesite.class.php
20:36:47amayercommited them to branch master
20:36:59Tornebluebrother: github encourages you to learn a workflow that's completely different from the one we use
20:37:01amayerthen i made the changes to db.class.php and commited it to branch master
20:37:21Torneso, telling someone who isn't very confident in what they are doing in git to go use that instead is unhelpful
20:37:24bluebrotherit does? I've never seen github as doing so
20:37:37wodzamiconn: pong
20:37:46Torneamayer: what i mean is, i approved your other change
20:37:51Torneso you could've just pressed "submit" on gerrit for it
20:37:53Torneit was approved
20:38:02bluebrotherrather as "a place where I can push things (and allow people to look at it)"

20:38:56AlexP_soap: Did you ban the ip?
20:39:27amayeroh. i didnt have to do anything to my last patch. i think someone did that for me and didnt tell me i had to do it

20:39:50AlexP_yes, the committer can also submit changes

20:41:44AlexP_scorche`: They are OK in general for me, it is just banning anyone (or similar admin) that is really slow

20:42:19amayerso i should learn alot more. i know the theory now. but i need to know how to execute what i want to do

20:43:29amayerwell i would like to learn branches
20:43:34amiconnwodz: Regarding the paste links you mailed - yes it looks like gcc used word sized jumptable entries there, hence the bug doesn't hit. Did you use -Os, and what gcc version was that?
20:44:01amayerthat way i could have worked on the db class and themesite class at the same time and had sepperate reviews that i could make changes too
20:44:15Torneamayer: i wouldn't've bothered making those separate changes in the first place
20:44:28Tornethe db cleanup is so tiny it's not really necessary to make it a separate patch :)
20:44:40wodzamiconn: both 4.0.3 and 4.6.3 with -Os. I did get byte jumbtable with -O2 but the code is a bit weird as it reshuffles the order of cases also.
20:45:15amiconnhmm.
20:45:41amayeri thought for the sake of the log i would put it in there so people could see that is where the database class was last edited
20:45:42amayer(hears echos in the themesite cave he is standing in)
20:45:44amayer...or just for my own sake
20:46:28amayerTorne: you merged the patch?
20:46:52amiconnIt may reshuffle the order of cases to shorten the maximum offset
20:46:59Torneyes
20:47:02amayerthanks
20:47:34amiconnIt probably won't do that if the (numerically) last case does have the biggest block of code
20:47:57amayershould i keep putting "themesite:" at the begining of commit messages?
20:48:06AlexP_please
20:48:07*amiconn wonders what's different between this test case and the sound setup function which has been crashing due to that bug back then
20:49:04amayerTorne: so now i do a rebase and commit my next change?
20:49:32Tornethe themesite is a completley separete repo, so i don't see the need to repeat it in the commit message
20:49:40AlexP_ah, forgot that
20:49:51Torneincluding it just makes the oneline summary longer :)
20:50:07amayerTorne: thats what i was thinking
20:54:30amayerTorne: when i add you as a reviewer does it send you an email or something?
20:56:06wodzamiconn: http://pastie.org/5139178 gcc-4.6.3 with -O2
20:59:09amiconnIs this patched or unpatched?
20:59:48Torneyes
21:00
21:00:46amiconnwodz: In this example, the largest offset is 0xc4, hence the bug won't hit
21:01:46*amiconn is building unpatched gcc 4.0.3 in order to put together an example that triggers the bug
21:02:13wodzamiconn: I know, but it is hard to predict the offset if gcc changes the order
21:02:25wodz4.6.3 is vanilla

23:55:36amayerim talking about the order on a page when sorted
23:55:42AlexP_and ascending/descending is low to high and vice versa
23:56:02AlexP_yes, but I don't know what rating alphabetically means
23:56:08gevaertsI'd say when equal, most ratings wins
23:56:24amayerTheme "A" has 5 ratings
23:56:26amayerTheme "
23:56:28AlexP_yes, if the average is identical
23:56:34amayerB" has 6 start
23:56:40gevaertsAnd when still equal then, go alphabetical
23:56:44amayerhold on let me retype
23:56:46AlexP_right
