03:04:38bieberI'm going to refactor my theme editor parsing code to work with parameter lists instead of coding individual parse functions for each tags (don't know why this didn't occur to me :/). For long term maintainability, would it be preferable to have configurations hard-coded as constants, or loaded from a configuration file?

03:16:36bieberIt should be easier, I guess my only real concern is whether it's a good idea to base critical functionality on a config file that has to be bundled with the program

04:07:06Blue_Dudefml: Good point re: hotkey tags. I'll go back and revisit them. They'll probably be gone in the morning.
04:13:58zouhairHi, anyone here kind enough to take a look at my plight :
04:20:56JdGordonbieber: hey, what do you mean parameterised lists?
04:21:33bieberJust a list of the parameters to a tag and their types and properties
04:22:10 Quit CGL (Ping timeout: 246 seconds)
04:22:30bieberi.e. something like 'V':width(int),height(int) ... and etc. I have no idea what format I'll actually end up using, but that sort of thin
04:23:04bieberThat would be in a config file, anyways. If it's hard-coded, there'd just be a class that specified the parameters for a tag
04:23:28 Join Forsaken [0] (~chatzilla@
04:24:41JdGordonI had an idea to simplify the parser so it could be more easily used directly by the theme editor
04:25:00JdGordonright now each tag does its own parsing which means lots of extra work for you...
04:25:38bieberThat's why I wanted to replace that with a generic function that could just parse according to parameter lists
04:25:57JdGordonwhat would be nice is if the handler for each tag accepted a char** of parameters, so no parsing was done in them, the same parser could be used by both
04:26:15JdGordoni.e the parser would split %V|a|b|c| into a usable array by both
04:26:59bieberSounds like a good idea, thanks
04:27:33JdGordonthe problem is that to do that the format has to change, which was the talk about %xx(a|b|c)
04:28:51JdGordonhow much work have you done on your parser?
04:29:29bieberI could still write a simple parser to recognize %ident(param'|')* or something like that
04:30:05bieberThe parser I have now is fully functional for the tags I've implemented, and for the rest it's going to be mostly boilerplate, as they're generally pretty easy to parse
04:30:16bieberBut that's still a lot of boilerplate, which is why I want to generalize the process
04:35:55JdGordonhmm... actually we could probably go directly to the full token array without using any special handlers? just copy the params into buffers and then handle them all at the end?
04:37:05bieberI do like the ability to use polymorphism instead of massive switch statements, but that could be preferable to having a separate class for all those tags
04:37:38JdGordonthis could also mean much better debug abilities
04:39:08JdGordonwell, now if a tag fails to parse itself it just fails and says which line it was on.. with this we could say "token xx expected a int for arg 3 but got 'a'"
04:39:43bieberThat would be more helpful
04:41:16JdGordonok, assuming tags must be in the form %aa %aa(b) or %aa(b|c|...) could a simple text->token array be done in c that we could share easily?
04:41:56bieberVery easily
04:41:59JdGordonthe bloody ; "tag" is going to be annoying to handle
04:42:37bieberThat would actually be regular, if all the parameters were guaranteed to be
04:43:11*JdGordon forgot conditionals
04:45:23bieberAside from the conditional tags, do the others all require simple values as their parameters?
04:46:25JdGordonall except the playlist viewer which right now does its own tag parsing on the last 2 params
04:47:02JdGordonbut I guess for that it could just run the full parser on them again
04:47:27JdGordon%Pv|0|%in - %ia|%fn|
04:48:04bieberYep, it'll be the same way for the conditionals: I'll just recursively call the document parsing function on them
04:49:18JdGordonif an array isnt good for the final list we can fiddle with the displayed to work more nicely with whatever
04:50:08bieberYeah, it'll have to be some kind of tree structure
04:50:35bieberAre you thinking about something that could be integrated into the theme engine or something? Since you were talking about a plain char* array and C code
04:51:18JdGordonyeah, I'd want to use the exact same code in rockbox for as much of the parser as possible
04:52:07JdGordononce the text is split into tokens and params you can go all c++y :)
04:52:28bieberThat sounds like a good idea
04:54:07bieberIf we're going to go down that road, I'd like to take it a step further and write a verifier the same way that could take the raw data and turn it into a parse tree that identified all the tags with enum values and checked their parameters and such
04:54:48bieberIf the theme engine people integrated that code into the theme engine, then the editor could just link to the files there, and at least parsing compatibility would be automatic, if not necessarily display
04:55:02JdGordonsounds good
04:55:20bieberDo you work on the theme engine? Or do you know if anyone would be interested in pursuing that?
04:55:26JdGordonright now checkwps does the ferification, but as i said, the debug output sucks

04:58:37JdGordonthe lib could be done in a way that it doesnt even care about known tags at all, just assume anything after % is always a tag, keept the identifier in plaintext then at the end turn the returned parse tree into a usable token tree/array/whatever
04:58:53 Join jfc [0] (
04:59:11JdGordonor does that sound slow?
04:59:25bieberI don't think speed is going to be an issue, really
05:00:05bieberThat part is easy, I just figure that if I'm going to do the syntax parsing C-style, I might as well do verification too, so they can both be handled by Rockbox and the Theme Editor from the same code files
05:01:14JdGordonthe verification needs to know what each tag requires for its params, so wouldnt that be seperate?

05:11:45JdGordonthe verification needs to know what each tag requires for its params, so wouldnt that be seperate?
05:12:30*JdGordon sent a email to the dev-ml about the format changes
05:12:47LloreanWhy exactly is the format changing?
05:13:09JdGordonto make it easier to read and parse
05:13:28bieberIt may or may not be, I think it's probably best to keep them separate
05:13:49bieberI could still do it in the same style, though, and both files could be used in the theme engine if desired
05:13:52LloreanShouldn't there be a significant discussion on what is "easier to read" then? Maybe hammer out a specific decision at devcon for how the tags should look, when a group can sit down and discuss it?
05:14:15 Join shai_ [0] (~Shai@
05:14:33LloreanI mean, your easier to read might be someone else's spaghetti, so one or two people changing the tag format (in a way that breaks compatibility, at least) probably shouldn't happen

05:17:10JdGordon<> means conditional
05:17:26bieberJdGordon: I mean verifying that it's semantically correct. They would still be separate functions, but you could chain them together and end up with a verified parse tree at the end

05:19:09LloreanJdGordon: So the idea is to make it quickly apparent when something is a conditional, and when it's something with parameters?
05:19:14JdGordonstruct syntaxTree *parseSyntax(char *text) would be nicer :)
05:19:28JdGordonLlorean: yes
05:19:40bieberYeah, I guess that will work better if you want to embed it in Rockbox
05:19:51LloreanMakes sense
05:20:08bieberAnd I apparently just got kicked for flooding? What's that mean, exactly? (IRC noob :/)
05:20:18JdGordontoo many lines too quickly
05:20:19LloreanSo you end up with a generic %Xd tag that takes which image to display as its parameter?
05:21:02bieberAh, got it
05:21:14LloreanJdGordon: There should *definitely* be a discussion of tag letter changes though (as per your possible idea in the email)
05:21:37LloreanThere are a lot of them that can be very confusing because they seem related to other tags when they're not.
05:21:54JdGordonfeel like putting a proposal forward?
05:22:36LloreanI might. I don't write themes, so I don't know if it might not just be better to leave the tags relatively close to what people have already learnt.
05:23:30LloreanBut if I were to reorganize it, I'd probably make the first letter always a category letter. For example, most %pX tags are "playlist" related, but then you have %pV
05:23:34 Quit Orion777 (Ping timeout: 260 seconds)
05:24:16JdGordonI'm thinking time to change to 3 letter tags even
05:24:28LloreanThat might improve things a lot.
05:24:38LloreanMore room for clarity
05:25:40JdGordonwe are at an annoying point in the release window now... so if we assume this doent go in till staright after the next release we have a few weeks to make that perfect
05:26:06JdGordonexcept I think the other changes should be quick so bieber's new awesome tokeniser can be usable soon :)
05:27:04LloreanIt'd be nice not to break themes until after the release. What would you use the new tokeniser for in the release version?
05:27:15LloreanI imagine anything else that would benefit from it would also be big enough that it'd probably be a good idea to wait.
05:27:56JdGordonnothing, but the theme editor (or at least the parser) should work on known working themes
05:28:01bieberWhen you talk about three letter tags, would they all be three letters, or is that optional?
05:28:42JdGordonright now tags are 1 or 2 letters, usually 2. I'd say up to 4 letters with most being 3
05:29:11LloreanJdGordon: I don't know if that's a good reason to have experimental new code in the release.
05:29:27JdGordonyeah, probably best to branch
05:29:40bieberWould it be the same structure you have now, where the first letter classifies it as part of a group of similar tags?
05:29:41JdGordonjust thinking we need to work with GSoC timelines also
05:29:48LloreanAren't there supposed to be SVN branches for the GSOC students to work in?
05:30:26Lloreanbieber: At the moment, the first letter doesn't classify anything. There are some patterns, but it doesn't actually mean anything but a word. So "p" can mean "playlist" or "percent" or anything else that starts with P.
05:30:56bieberOh, okay
05:31:07LloreanIt'd be really, really nice if there were some classifications though
05:31:29LloreanIf we said "use p for playlist, m for metadata, a for audio state, f for file properties..."
05:31:33JdGordonespecially now that we have more than 1 screen where tags are usable
05:31:48LloreanAnd three letter tags would help keeping that flexible.
05:33:11JdGordonABCD - A being optional is the skin it works in (Wps, Base, Fm, Rec, etc), B being general group (Metadata, Settings, etc), C being more specific group, D being tag
05:33:51LloreanMaybe A not being optional, and having a code for "all screens"
05:34:37JdGordonthis part of the topic needs to be discussed, probably in the forum where the themers generally are more active
05:35:57LloreanSeems like a good idea.
05:42:23JdGordonactually i wonder if 4 is too many, making lines way too long
05:43:05bieberHow many tags do you typically have on a line
05:43:48LloreanSome people pile an awful lot of tags on a line.
05:43:58LloreanBut in many cases they probably just don't know they can split lines up
05:44:03JdGordon30+ isnt unheard of when using conditionals
05:44:21LloreanJdGordon: Though to be honest, a lot of those are volume bars and such, which can be replaced with progressive bars.
05:45:01bieberWhile we're changing things, why not allow multiple-line conditionals and the like without the comment hack?
05:45:55JdGordonyes, but how? require the line end with the |?

05:46:41bieberThat could work
05:47:00LloreanI think the comment "hack" as it were looks / is pretty good actually
05:47:12LloreanComing at the end of the line, it's a unique line-ending character.
05:47:27bieberI guess that makes sense
05:47:47bieberYou could also consider the \ that a lot of formats use to allow explicit line continuations
05:48:19JdGordon%<line end> would be more consistent here
05:48:33***Saving seen data "./dancer.seen"
05:49:12LloreanI'd say \ or just #. A single character is nice, I think.
05:49:37LloreanThe # is pretty much going to have to stay anyway, unless comments change to not eat lines (or can't be done mid-line) in the future.

10:31:07amiconntrapf is essentially a trap that is never taken ("trap false"). It's purpose is that you can shadow one or two other instructions, by putting them into the extension word(s) of trapf.w resp. trapf.l
10:31:45amiconnThis saves cycles if you have an if/else construction with just one or two instructions in the else path
10:32:05amiconnAn unconditional branch is 3 cycles, while a trapf is single cycle

10:33:23wodzamiconn: so imidiate argument to the trapf is in fact decoded instruction right?
10:34:42amiconnIt's not decoded if instruction flow "runs" into the trapf instruction, but you can branch "into" it with a conditional branch

11:35:58pamauryok, I'll do my best to do it perl/python even though I do not code myself in either of this languages ^^
11:37:56JdGordonmaybe it would be simpler to not do a generic transform and work on the changing tags only (for which there are maybe a dozen)
11:38:06JdGordonjust thinking that getting it right inside conditionals is giong to be tricky
11:39:11Zagorhow could anything be simpler? B-)
11:39:52JdGordonwould that actually work?
11:40:01JdGordonthat wont get the messy ones inside conditionals
11:40:06pamaurydepends on what you want to achieve
11:40:07*Llorean doesn't know regex at all but thinks that might depend on %aa being present.
11:40:50ZagorJdGordon: I don't know enough details of the wps format to say
11:41:41Zagorsure, except no parenthesis around \1
11:42:35Zagorbut yes, I fully understand that this is rather messy for someone not comfortable with regex details.
11:43:24JdGordonIf that got 90% I reckon that would be good enough
11:43:31JdGordonexcept no it wont work
11:43:54JdGordon%?aa<%ab|blaa|fds> would get wrongly done
11:44:31pamauryWhat is the expected result with this ?
11:44:32JdGordononly do that regex is you arnt inside <>'s would get 99%
11:44:45Zagorpamaury: see the mailing list. JdGordon is going to change the wps syntax.
11:44:48LloreanIt might take longer, but wouldn't it be safer to just use an existing list of tags and check each one individually?
11:45:01JdGordonor that
11:45:09JdGordonlike i said, only maybe a dozen are actually changing
11:45:17LloreanIf we can parse existing WPSes without ambiguity, this script should be able to be 100% at least for reading and identifying
11:45:23LloreanThe only problem is writing things back in a reasonable manner.
11:45:45ZagorJdGordon: that regex won't match inside <> since it assumes a trailing |
11:46:12JdGordonit would get the first one though, wont it?
11:46:22pamauryThe best way seems to use the existing parser and output the transformed file, keeping enough information about spaces, newlines and comment
11:46:46ZagorJdGordon: no, \w only matches alphanumeric characters, so no < or %

11:47:40ZagorJdGordon: sorry, wrong response. no it will ignore it since the string doesn't match the pattern. (no trailing |)
11:47:51LloreanInstead we should provide an webpage where authors can run it on their own themes and resubmit.
11:48:05LloreanMake it trivial for them to fix their theme, but let them choose not to (at least until the first release with the new parser comes out)
11:48:32JdGordon%?aa<%ab|blaa|fds> %ab|blaa| would match it though?

12:32:48kugelJdGordon: I just found that inconsistent
12:33:10kugelwe could remove %Vl, couldn't we?
12:33:14JdGordonoh right
12:33:18JdGordonI see what you're saying
12:33:25JdGordonyeah, we could
12:33:42*kugel would rather have optional params at the end
12:34:15JdGordonlets do this break first then figure out which tokens really need replacing/fixing
12:34:56kugelbreak another time just after the big breakage?
12:35:48JdGordonas long as it happens in one release cycle its fine
12:36:04JdGordonor we really want to completly destory everything?
12:36:12JdGordonin which case there isnt much point having a convertor is there?
12:36:19kugelthe first breaks it completely already
12:36:30JdGordonrelativly simply though
12:36:37kugelremoving %Vl could be part of the converter
12:37:13JdGordondo i just do svn branch to create one?
12:37:38kugelno, you do svn cp
12:38:20kugeldo you agree with optinal parameters at the end? that helps consistency
12:38:29*amiconn usually uses as a reference
12:38:56JdGordonthe placement doesnt really bother me
12:39:10kugelI think "%xd<one or two letters) -> %xd(letters)" should be "%xd<one or two letters) -> %xd(letter 1,letter 2)"
12:39:11JdGordonI would like general concsistancy across all tags though
12:39:37kugelwhich is exactly what I'm saying
12:39:40JdGordoni.e the id field should be the first for all things that have a id, optional or otherwise
12:40:15JdGordonand no, if we do your idea than %xd(a,b) would be different to %xd(ab)
12:40:32JdGordonthe first being enable the a and b images, the second is enable the 2nd subimage in a image
12:41:37kugelJdGordon: not if we do the other idea of different delimiters for repeater params
12:42:10kugelI think it should be clear that one is a parameter list and the other is just a simplification for repeated tags
12:42:43JdGordonan example?
12:43:21kugel%xd(A,a) <-> %xd(A;B)
12:43:43kugelcould even do %xd(A,a;B,b) then
12:44:00 Join Forsaken [0] (~chatzilla@
12:44:17JdGordonthat doesnt look very nice
12:44:28kugelif there's a ; (assuming that's the repeater delimiter), it would just call the tag parser multiple times for the args
12:45:38JdGordonapart from the xd tag, where else would that be useful?
12:46:03JdGordonit would be simple enough to just put that logic stright into those tags
12:46:30kugelwhy don't make it generic?
12:47:06JdGordonit feels messy, but either way, adding that wont break anything
12:47:26kugelI don't think the repeater thing is very important, we can worry about it later as adding it later shouldn't break things
12:47:41JdGordonso the origional point is that %xd(aa) is simpler than %xd(a,a)
12:47:50JdGordonnot simpler... umm... flexible
12:48:09kugelit's only inconsistent imo
12:48:24JdGordonnot really.. aa is an id
12:48:59kugelif you follow %xl, then the subimage is an additional, optional parameter
12:49:02kugelso it should be for %xd
12:49:31kugeldoing %xl(A,a) but %xd(Aa) is incosistent
12:51:31JdGordondoing that means we have no choice but to use a different delimiter (which will make the parser slightly omre complex) or being stuck with long lines of %xd(...)'s
12:51:59kugelI'm very much in favor of a different delimiter
12:52:05JdGordonor.. %xd(A,d,B,F,d,e) is slightly ambiguous
12:52:14kugelusing the same for parameters and repeaters is confusing
12:52:17JdGordonof course we could know that B doesnt have subimages
12:53:46kugelwe could with unecessary extra logic in the parser
12:54:03JdGordonputting the repeater logic in the handler will dupe some code but make the important parser simpler
12:54:07kugela separate delimiter is easier for parsing and less confusing for themers
12:54:18JdGordonmaking it generic for 2 or 3 cases doesnt really make much sense
12:54:35kugelgeneric is less code though
12:54:53JdGordonin a more complex area
12:55:58wodzwhy don't we use xml-ish format?
12:56:09kugelI think the parameter parser would be the least complex part, the individual tags are more complex
12:56:38*JdGordon glares at wodz
12:56:41JdGordonxml is never the answer!
12:57:01wodzbut is easy to parse
12:58:11JdGordonkugel: my tihnking is this, I want the parser to split up the args and pass them as a char** to the handler which then works on the individual char*'s.. the debbuger could then very easily know if it got a number when it wanted a filename
12:58:23JdGordonthe tag parsers then become very dump

13:09:39LloreanProposal for 3.6: Finally remove "Fade on stop/pause" as defaulting to on.
13:11:09Zagoroh right, is it still that silly long fade?
13:11:13LloreanZagor: Yes.
13:11:36Zagorbleh, that's a bug. we should simple fix the default to be as it was intended. (a replication of winamp's fade on pause)
13:11:50LloreanIt looks unresponsive because it seems to take a while to pause (it can look buggy) and (to a lot of the people we talked with about this) it's basically just a feature that immediately gets disabled anyway.
13:12:07LloreanI'm a big fan of most features disabling to "off" and needing to be turned on anyway
13:12:21Zagorit should be a fraction of a second, just to take the edge off
13:12:39LloreanIf it were very quick, it probably wouldn't be as annoying, yes.
13:13:10JdGordonif it were done right and not faked with fiddling with volume it would be less annoying
13:13:49Zagorit was done in hwcodec times
13:15:11LloreanWell, maybe it should be disabled by default for now, then we can ask people what they prefer when a properly working one exists?
13:15:50Zagorif it isn't fixed before the next release, I agree default should be "off"

13:17:17S_a_i_n_tI don't think it should be off...but it should be a *very* short fade,

13:22:10Blue_DudeSaw something about "fade on stop/pause". That's something I'm working on doing in the mixer. So at least swcodec will be fixed eventually. Hwcodec will still probably need to do it as a volume fade.
13:23:13S_a_i_n_tit just needs to fade out quite a bit quicker on pause than it does now...
13:23:28Blue_DudeIs 23 ms short/long enough for the job? Any multiple of that will work well.
13:23:48Blue_DudeIt will happen within 23 ms. :)
13:23:51LloreanI think the shorter the better.
13:24:09Blue_DudeI meant the length of the fade though.
13:24:14LloreanBut 23 might be a little too short to be noticieable.
13:24:18S_a_i_n_tthat would probably be nicer than it is now.
13:24:34S_a_i_n_tperhaps 46ms?
13:24:36LloreanI'm guessing (based off nothing at the moment) we'll probably settle on something between 100 and 200
13:25:17Blue_DudeIt will occur within 23 ms of the button press, but it can be any multiple of that for the fade itself. Keeps the code cleaner. (23 ms is the mix buffer size).
13:25:23LloreanIt may make sense to have a setting for the fade duration anyway, at which point we can all try it and see which seems a good default
13:25:42Blue_DudeBleh. I thought you didn't like menu items like that.
13:25:53LloreanThere's already a menu item to turn it off/on
13:25:59LloreanReplace it with "Duration" that starts at 0.
13:26:10LloreanNo net increase in menu items, just an increase in functionality.

13:31:20Blue_DudeHm. What, 0, 23, 46, etc.? Not pretty.

13:32:01Blue_DudeWith hardcoded presets.
13:32:03LloreanOr "short, medium, long" being 46, 115, and 230 or something
13:32:14LloreanBut yeah, exposing the numbers would be ugly
13:32:27Blue_DudeSubject to experimental changes later.
13:32:49LloreanBut I think that if the feature is to exist, it needs a little flexibility otherwise it's really there for a very, very small subset of users.
13:32:56LloreanEither that, or it needs to be something that more or less universally sounds good.
13:33:05LloreanIn which case, it may not even need an on/off
13:33:34S_a_i_n_tI think even 46 would be barely audible, perhaps a slightly longer setting for "short" than 46ms
13:34:21ZagorS_a_i_n_t: yes. an enterprising soul might measure how long winamp fades.
13:34:45Blue_Dude"Barely audible" seems about right to me. I use a hard stop myself. Fade bugs me.
13:34:54S_a_i_n_talas, I do not have a winamp to measure.
13:35:03ZagorBlue_Dude: then 0 is for you
13:35:14Zagordon't ruin the function because you want it off
13:35:30S_a_i_n_tI like the fade on stop/pause setting, but, the fade is slightly too long IMO
13:35:33LloreanI think "barely audible" is good for short
13:35:43LloreanIt should take the edge off without being something you can notice unless you're looking for it hard.
13:35:43S_a_i_n_tit needs to be about halved in duration.
13:35:50Zagorthe feature as-intended is very nice. it's just the current incarnation that's silly.
13:35:52Llorean"medium" should be the setting for most similar to winamp
13:36:01CIA-5New commit by 03wodz (r25948): HD200 - fix in asm optimised ATA reads&writes
13:36:03LloreanAnd "long" should feel like it's actually fading.
13:36:27LloreanS_a_i_n_t: I'm pretty sure the current setting halved would still be well, well over the 230ms I mentioned for long
13:37:00Zagorthere should be no noticeable delay in pausing. just a smoother cut-off.

13:39:48S_a_i_n_tCould you please add "insert shuffled" to the file-tree hotkey?
13:40:08Blue_DudeCould be. What's it worth to you?
13:40:24Blue_DudeDon't answer that.

13:40:40Blue_DudeYeah, that's a trivial addition. Consider it done.

20:18:35Buschelwodz: regarding your comparison of pixelma's test_mem results (several MB/s) with yours (some hundred KB/s) -> you need to use current svn's test_mem plugin. there were several changes in the last days to optimize for ARM and to correct the calculation of memory bandwidth. in your version you will have to multiply the result by 100 to have the real bandwidth (e.g. your 200+ KB/s equal 20+ MB/s).

20:22:09Buschelok. fine :)
20:22:55wodzBuschel: wouldn't it be better to use memset/memcpy in test_mem? coldfire has optimised versions thanks to amiconn
20:23:16wodzthe question is what we try to benchmark
20:24:00n1swodz: looking at your ata-as-mpio change, it looks like you could save an instruction in a few places by replacing and.l #0xff, %d0; or.l %d0, %d2 with move.b %d0, %d2
20:24:28wodzmove.b does not clear rest of register
20:24:41wodzso I can't do or next
20:24:43Buschelwodz: we could add this measure as well. but I like to have separate results for read and write. e.g. in codecs you may read large amounts of date from iram to save a single results in dram (like used in filters).
20:25:24Buschelwodz: memcpy or memmove would be more symmetric
20:25:32n1swodz: i mean replace the and and the or with the move.b just copying the lsB from d0 into the lsB of d2
20:26:02wodzn1s: aa right this will work
20:26:57wodzn1s: I wanted to review the code once more when merging into ata-as-coldfire.S
20:27:27preglowamiconn: planning to optimize the arm flac routines for higher bit depths?
20:27:35n1si definitely think a merge is a good idea, and one can never review too many times ;)
20:28:06wodzBuschel: but now we can't in any way compare results from different architectures
20:29:41Buschelwodz: as I said, we might add memmove and memcpy to have asm'ed versions for the different architectures. and in addition mr. someone might add asm for other architectures for the read/write tests :o)
20:29:52wodzBuschel: writing optimized routine for every architecture just for test_mem is waist of time
20:30:16Buschelthat is your opinion
20:30:43wodzwhat information does it gives you?
20:31:20Buschelimplementing it might be fun for some of us ;o)
20:31:22wodzit is much better to benchmark code which is used in some other places in rockbox
20:31:31 Nick YPSY is now known as Ypsy (
20:32:40Buschelwodz: you are missing some major point here: codecs (that's what I mostly work on) _are_ specific in their decoding/synthesis filtering. there is no memcpy or memmove used in the relevant parts. so it is of interest how different memory concepts scale
20:33:58 Quit flydutch (Quit: /* empty */)
20:34:04kugelmy intention for test_mem was to check if something is wrong with the fuzev2 actually :)
20:37:32pixelmaBuschel: so you were working on test_mem? Could you look into the issue why "boosted"/"unboosted" often states the wrong thing? Looking at the displayed clock and related speeds seems to be correct but the words don't match
20:37:45kugelthat was one mutex unlock too much, now buttons work again
20:38:09pixelmaon my M5 that is at least
20:40:13Buschelpixelma: that's the same on my machine (iPod 5.5G). seems like there is a delay between triggering the boost ("boosted" is displayed) and the clock change itself. not too interesting though: just wait until the boosted clock is displayed and everything is fine :o)
20:40:50Buschelpixelma: good enough for a tes plugin :o)
20:41:16pixelmaI mean a mismatch between the words "boosted" and "unboosted" and the clock speed displayed along with it
20:42:55pixelmaand yesterday the plugin just stopped on its own without me doing anything and after different amounts of time. I didn't see a pattern
20:45:32Buschelpixelma: I can see the same behaviour regarding boosted and the clock (too much cpu consumed to switck clock? maybe you could just enlarge the get_action timeout?). But I did not experience any plugin exits...

22:22:39m0arOh, thanks
22:22:50Bagderthe main reason is all the money and fame it brings with it!

22:29:38m0arWell, I'll have it charged
22:29:49Torneso the risk is very small
22:30:13Tornethe bootloader installer only works with original firmware updates which we have tested and included the checksum of

22:30:53m0arYeah, that's why I came in here :D
22:31:06Torneoh, you might render it useless at any moment, but not *permantly* :)
22:31:17m0arI meant permanently.
22:31:29m0arAs in:
22:31:35evilnickm0ar: Which section are you referring to?
22:31:38Tornevery few targets have any measurable risk of bricking unless you do something really stupid
22:31:41evilnick(on the wiki)
22:31:50Tornesome of theunstable targets might randomly reformat themselves or corrupt the data or whatever
22:31:54m0arthere's always a risk of BRICKING your device PERMANENTLY., which repeats again and again
22:31:57Tornebut it will just kill all your music and force you to reinstall rockbox
22:32:15Tornegenerally there's no risk of bricking the device once you have installed the bootloader
22:32:18Torneunless you install a new bootloader.
22:32:19m0arWell, good :)
22:32:22evilnick"Even though the bootloader installation and rockbox itself are tested, there's always a risk of BRICKING your device PERMANENTLY."?
22:33:06m0arevilnick: Well, the red text warning for a takedown lurks in a few places more. The fact that it's well-repeated made me wonder :)
22:33:19Bagderwe want the warnings to be big and bright so nobody comes down and say we didn't warn them, for the odd case where something actually does go wrong
22:33:49m0arProbably some guy that gets tired of waiting for the "firmware update" and just forces it off
22:34:05m0arA question, why isnm't it possible to reinstall a standard bootloader if installation fails?
22:34:17Tornebecause the firmware is what installs the firmware, on a lot of players :)
22:34:36Torneif you break it there's nothing left to install another one with
22:34:39Bagderif installation fails, the device is dead
22:35:12Bagderwell, at least it some cases ;-)
22:35:23m0arWhen I get my player I'll come in here and nag you guys while I do this, minimizing the chances of me failing miserably
22:35:51Tornewe'd rather you didn't
22:35:53evilnickIt *should* be perfectly straightforward to follow the instructions and do it on your own
22:36:16Tornefollow the instructions, and ask us if something is unclear
22:36:26m0arTorne: Yeah, that's what I meant dude
22:37:12AlexPAlso, make sure to read the manual before asking
22:37:18m0arOf course

23:00:00FlynDiceTorne: can you point me to the message
23:00:40Tornegevaerts already responded with "have you tried resetting it" which is probably sufficient :)
23:00:43Tornei just found the timing amusing
23:03:38Stephen__is there a link to the current source ? as opposed to using svn ?
23:04:12bluebroStephen__: no, we don't provice an svn tarball anymore. There isn't much point in doing so
23:04:52Stephen__ > should be changed where it says: Daily builds, voices, fonts and source
23:04:59Stephen__I just grabbed 3.5.1 anyways
23:05:33bluebrogood point.
23:05:40*bluebro looks around for Bagder
23:06:33*Bagder jumps out from the shadows and says "g'day sir, you called?"
23:08:11 Nick Ypsy is now known as YPSY (
23:09:58 Quit Xerion (Quit: )
23:10:29bluebroBagder: any thoughts on removing the "sources" line from the daily build page? (The "Daily builds, voices, fonts and source" on that is)
23:11:12Bagdermaybe we should have daily sources...
23:12:46Tornewastes our bandwidth, no?
23:12:58Tornecan we just get ar ead-only http svn mirror instead?
23:13:06Torneso that people who can't access svn because of firewalls can use it?
23:13:10 Quit evilnick (Quit: Page closed)
23:13:32Tornewell i say mirror, i just mean a mod_dav_svn on the machine that hosts the svn-protocol svn at the moment
23:14:16bluebroweren't the daily tarballs removed because they caused too much work (those FILES files IIRC?)
23:14:38bluebrobut I wouldn't object to daily sources. I won't be the one to implement that anyway :)
23:15:03Tornesvn not being accessible behind some firewalls is about the only sensible reason why telling people to use svn isn't sufficient, imo
23:15:12BagderI agree
23:15:16Torneif people are going to compile the source, then they alrady need a whole bunch of stuff
23:15:22Tornerequiring that they also have svn is not exactly arduous
23:15:35Torneand http svn is not hard to set up as long as you only support reads
23:15:42Tornesince you don't need any access control then :)
23:15:44joeygwe could move to git and gitweb ;)
23:16:17bluebroand what's the gain with git in that area? ;)
23:16:34Bagderit's not even shorter than svn! ;-)
23:16:50bluebrothen we'd need to move to hg!
23:17:10Bagderoh indeed, I'm now convinced!
23:17:27bluebro(though I liked git much better than hg when trying)
23:19:01joeygyou can use git over http i believe
23:19:07joeygso no firewalls to worry about
23:19:18Torneyou can use svn over http
23:19:22Torneso that's not really an argument
23:19:59joeygyou suggested svn was not accessible behind some firewalls - in what way?
23:20:18Torneat the moment we expose the repository only through the "native" svn protocol, on the port number usually used for that protocol
23:20:30Tornesome people's networks only allow connections to fixed ports
23:20:37Torneproxy-only internet access and all that
23:20:48joeygi gotcha
23:20:48bluebrogit is completely different than svn. While I like it pretty much I don't see much gain for the project when switching to git. It we were still using cvs the things would be different ...
23:21:04Tornemod_dav_svn exposes svn repos through WebDAV, which then works on port 80 same as everything else
23:21:18Tornebluebro: i just ignore everyone and use bzr
23:21:20Bagderbluebro: being a git convert myself now, I *do* see a benefit from using git ...
23:21:29Torneand if the project switched to git i would continue to use bzr :)
23:21:45joeyg:) i use git-svn with no trouble at all
23:21:58joeygthough im exploring the s9 so im off in my own little world..
23:23:08bluebroBagder: of course there are benefits, but with git-svn everyone can chose :)
23:23:29*bluebro didn't like the branching handling of bzr
23:24:24Tornebluebro: it's just a UI thing
23:24:41Tornegit has a totally different way of working to all the others (which are all much the same as each otehr)
23:24:52Tornebut they all do almost *exactly* the same things in almost exactly the same way really
23:25:27bluebrowell, I wouldn't call this "every branch needs its own folder" a UI thing compared to git's "only one work area"
23:25:35Tornebut they don't.
23:25:40TorneAnd it *is* a UI thing
23:25:43bluebrobut yeah, from the functional point of view it's pretty much the same
23:25:49Tornethe underlying data is identical
23:26:10Tornealso, my rockbox folder has 20+ branches and only four folders :)
23:26:52Tornealso also, you can work exactly the way git works if you want
23:26:57linuxstbjoeyg: I've just read the recent posts in this thread - - you can just post the URL I gave to the windows binary. Which BTW, I cross-compile on Linux using the mingw32 package - just install that and type "make tcctool.exe"
23:26:59Torne(mine is using a nonstandard plugin, but hey)
23:27:11Torneyou just make the branches without workdirs, and then do a lightweight checkout to someplace else
23:27:18Tornethen you can switch the branches of that checkout, exactly as with git :)
23:28:04bluebrowell, I really found that confusing. Especially the explanations the UI gave me (this tortoise-like interface that comes with bzr in my case)
23:28:37joeyglinuxstb: thanks, i'll post that link when i get home from work
23:28:48joeygand thanks for the mingw32 tip, i had no clue that's what that was
23:28:57Tornei'm not sure why branches being directories is confusing, though, still.
23:29:04Tornei find git's way *extremely* confusing
23:29:10Tornei much prefer being able to see it there in my filesystem
23:31:28joeygive always liked git's way
23:31:42joeygjust typing 'git init' on every new project, then 'git branch' to see branches

23:34:46 Quit CGL (Quit: Soy spammero ---- \m/ d(>.<)b \m/)
23:35:37Tornejoeyg: but i build anything up to half a dozen branches of rockbox at a time
23:35:49Tornejoeyg: having them in seperate directories to start with makes that trivial
23:36:09CIA-5New commit by 03alle (r25958): Add the cyrillic 'yo' to 12-Adobe-Helvetica font
23:37:02joeygthough, you could add 'git branch' instructions to your build script and get a similar effect
23:37:26joeygi agree that's a silly pain though
23:38:27Tornei understand how to work with it, i just don't see where it's an *advantage*, excpe tit takes slightly less disk space
23:38:31Tornedisk space is cheap ;)
23:39:46Torne(and as i noted above you can not hav ea working tree checked out in each branch, if you want, and just keep any number of seperate trees)
23:40:23joeygit lets git store branches as diffs of each other and with its linked-list type structure
23:40:30joeygwhich is a fair bit faster and simplifies merging
23:40:35Torneer, bzr does that though
23:40:41Tornei only have one copy of all my revisions
23:41:09Tornethe seperate branch folders are just a tiny metadata file that says which commit is the tip of that branch
23:41:13Torneand then optionally a workdir
23:41:28Tornethey're in folders because the usual case is to have a workdir, so they need to be in one anyway
23:41:52*gevaerts finds this all very interesting, but...
23:41:59Torneokay yeah, this is kinda offtopic ;)
23:42:07joeygalright :)
23:42:14TorneBagder: are you the one to pester about getting http access to svn, though?
23:42:20Tornereturning to the actual point :)
23:42:33*Bagder whistles as he's slowly hiding behind gevaerts
23:42:41AlexPThat would be useful :)
23:43:10Bagderme or zagor would be the guys to pester, yes
23:43:39Bagderbut since zagor is younger, you should poke on him!
23:43:47AlexPhaha :)
23:43:50scorche|shand he isnt shunning devcon!
23:44:06Bagderright, you'll reach him easily then!
23:44:21Tornewell, i don't personally need it.. it's just that *sometimes* people have the valid reason that they want to ahve a source archive because they can't get to svn
23:44:27Torneso we should maybe fix that
23:44:34Torneso we can just accuse them of being lazy instaed ;)
