| 11:15:45 | gevaerts | No idea. I haven't disconnected USB with current svn |
| 11:16:36 | gevaerts | Can you add the patch at http://paste.debian.net/126486/ ? That should provide a bit more information in the panic message |
| 11:17:19 | GigaBrick | All right |
| 11:23:04 | GigaBrick | gevaerts, I got "buffer_alloc() : scrobbler_init:251 exclusive buffer owner" |

| 11:23:37 | GigaBrick | Oh, that makes sense why it stopped reproducing |
| 11:23:50 | GigaBrick | I turned the Last.fm log off anticipating a lot of crashes |
| 11:23:58 | GigaBrick | That's when the panics stopped too... |
| 11:25:03 | gevaerts | GigaBrick: maybe a silly question, but is the panic text wrapped? |
| 11:25:17 | GigaBrick | Meaning it starts on a new line? |
| 11:25:21 | GigaBrick | Yes |
| 11:25:53 | gevaerts | kugel: do you mind if I commit that patch so these panics get easier to trace? |
| 11:26:07 | gevaerts | Or will it mess up your tree too much? |
| 11:26:27 | GigaBrick | gevaerts, it wraps at "...lusive buffer owner" if that's helpful to know |
| 11:26:28 | kugel | gevaerts: yes |
| 11:26:46 | kugel | it messes up my tree, and it will be obsolete |
| 11:26:59 | kugel | because with buflib it doesn't panic anymore |
| 11:27:05 | gevaerts | ah, ok |
| 11:27:21 | * | gevaerts isn't awake, clearly :) |
| 11:27:33 | gevaerts | I forgot. That's what buflib is *for*... |
| 11:27:56 | kugel | :) |
| 11:28:15 | GigaBrick | Well, I was right about disabling the last.fm log making the panic stop |
| 11:28:47 | GigaBrick | So I'm guessing there's a function called scrobbler_init that's to blame? |
| 11:29:55 | gevaerts | Yes, or that area anyway |

| 11:56:31 | kugel | hm, I suspect the shutdown is rather to force flushing of the last.fm logs, but that's also handled already by the ata idle callbacks |

| 12:01:44 | | Part Zagor |
| 12:01:55 | kugel | gevaerts: the ata notify callbacks always work, no? or is there some trick? |

| 12:02:03 | kugel | like it doesn't do anything on flash |
| 12:03:46 | gevaerts | As far as I know they should always work |
| 12:04:36 | kugel | so the patch relies on that callback to flush last.fm log to disk on usb |
| 12:04:44 | kugel | and stops the stupid re-allocation |
| 12:06:03 | kugel | my mail to -dev didn't catch a lot of attention yet :( |
| 12:09:04 | GigaBrick | Well |
| 12:09:08 | GigaBrick | I don't get that panic |
| 12:09:19 | GigaBrick | But now after disconnecting the usb I get "Error accessing plyalist control file" |
| 12:09:24 | GigaBrick | Then "Invalid control file" |
| 12:10:27 | GigaBrick | Then when I try to build the playlist again it says it can't update the control file |
| 12:11:05 | kugel | is that when you played music before usb? |
| 12:11:33 | GigaBrick | Yeah |
| 12:11:49 | GigaBrick | Well, I rebooted and can load playlists and stuff now |
| 12:11:57 | GigaBrick | Though looks like I ran into that database duplication thing |
| 12:12:01 | GigaBrick | Because now I have double of everything |
| 12:12:31 | kugel | :'( |
| 12:13:17 | GigaBrick | Yeah, I've seen that "Error accessing playlist control file" before |
| 12:13:25 | GigaBrick | But it always loads after I try it again |
| 12:13:36 | GigaBrick | Haven't seen it say Invalid before |
| 12:13:52 | kugel | is that also reproducable? |
| 12:14:01 | GigaBrick | Yeah |
| 12:15:47 | kugel | I'm not sure that's caused by my recent changes |
| 12:15:59 | GigaBrick | I don't think so |
| 12:16:09 | GigaBrick | I think it's related to the issue gevaerts fixed |
| 12:16:26 | GigaBrick | Because I notice it only does it when it would panic ( well, now instead of panicing it pauses for a second) |
| 12:16:59 | gevaerts | GigaBrick: try increasing that sleep time a bit more, maybe? |
| 12:17:41 | GigaBrick | Okay |
| 12:17:43 | GigaBrick | I'll give that a try |
| 12:17:51 | GigaBrick | I have to let my database re-initalize right now though |
| 12:17:59 | GigaBrick | PIty, I just rated a bunch of songs :( |
| 12:20:37 | sideral | GigaBrick: Try exporting the DB data before regenerating it |
| 12:20:45 | sideral | there's a good chance the data can be recovered |
| 12:21:02 | GigaBrick | Yeah, I considered that only after hitting "Initialize" |
| 12:21:06 | GigaBrick | So too late now heh |
| 12:21:18 | sideral | Also, please log the steps that led to the duplication to FS #12129 |
| 12:21:19 | fs-bluebot | http://www.rockbox.org/tracker/task/12129 Duplicate database entries (bugs, unconfirmed) |
| 12:21:39 | sideral | Did you interrupt a DB update with a reboot? |
| 12:22:09 | GigaBrick | No, it was related to an error acessing the playlist control file |
| 12:22:12 | FBI_Guy | is there a way to copy replaygain info from file to file without replacing the entire file? |
| 12:22:51 | sideral | GigaBrick: interesting... |
| 12:22:59 | GigaBrick | Yeah, I'm not really sure what happened to be honest |
| 12:23:14 | sideral | I don't really understand when that error can actually occur |
| 12:23:33 | sideral | Perhaps it's related to a dircache shutdown |
| 12:24:01 | GigaBrick | We were working through an unrelated panic from scrobbler.c I got when disocnnecting from USB... When it tried to resume I got "Error accessing playlist control file", which I've seen before, but usually can just resume... THis time it said "Invalid control file" and then wiped the playlist, so then when I tried it said "Nothing to resume" |
| 12:24:34 | sideral | (Just a guess because Slasheri and I recently fixed two bugs related to that in the playlist and DB code; there may be more lurking around) |
| 12:24:35 | GigaBrick | So then once that happened I went to my database to reload the playlist, and when I clicked I got the message "~9000 found" and knew it was dup'ing because my collection is only about 5000 tracks |
| 12:25:49 | sideral | When that happens next time, could you please check the database and dircache status pages in the debug menu? |
| 12:25:57 | GigaBrick | Okay |
| 12:26:08 | GigaBrick | The "Error accessing control file" is fairly reproducable though |
| 12:26:13 | GigaBrick | So I can probably check that right now |

| 12:26:56 | Llorean | FBI_Guy: I'm not even sure what you think you're asking, honestly. Replaygain info is unique to either the track or album anyway, and it's just metadata. I can't even imagine why you'd need to "replace" a file anywhere in the replaygain process. |
| 12:27:01 | gevaerts | GigaBrick: try checking the filesystem. You've had so many panics recently that I'm not entirely convinced that that's still going to be clean |
| 12:27:12 | GigaBrick | Yeah, sideral |
| 12:27:38 | GigaBrick | Good idea, gevaerts |
| 12:28:11 | GigaBrick | sideral, I've got the dircache debug page open |
| 12:28:19 | GigaBrick | After getting the "Error accessing playlist control file" splash |
| 12:28:29 | sideral | is the dircache still enabled? |
| 12:28:53 | GigaBrick | Says "Cache initialized: Yes" if that means yes |
| 12:29:01 | sideral | yeah, that's what I meant |
| 12:29:09 | GigaBrick | k |
| 12:30:10 | sideral | and what does the DB debug menu say? |
| 12:30:21 | sideral | first three lines? |
| 12:30:38 | GigaBrick | "Intialized: yes, DB Ready: Yes, RAM Cache: Yes" |
| 12:31:01 | GigaBrick | Also, under progress it says 87% (9145 entries) |
| 12:31:10 | GigaBrick | Does that mean it duped again? |
| 12:31:43 | sideral | No idea −− you'll have to check in the DB browser |
| 12:31:44 | GigaBrick | Or maybe that's all still loaded in RAM from before I re-initialized? |
| 12:31:49 | GigaBrick | Okay |
| 12:32:07 | Slasheri | found entries does not correlate to the number of tracks |
| 12:32:07 | GigaBrick | Nah, doesn't seem like it duped again |
| 12:32:27 | Slasheri | it includes every file and directory on the player |
| 12:32:40 | GigaBrick | Oh, okay |
| 12:32:51 | sideral | Looks like everything is fine and dandy this time. But you didn't add/remove files over USB this time around, right? |
| 12:32:55 | GigaBrick | Just coincidence it happened to be almost twice my collection |

| 12:33:36 | JacekNiesobski | hello everyone |
| 12:34:00 | GigaBrick | gevaerts, looks like you were right |
| 12:34:12 | GigaBrick | Just fsck'd and ./.rockbox/.playlist_control got flagged |
| 12:34:22 | sideral | GigaBrick: So the playlist error is probably unrelated to the DB problem −− if there ever was any (you did observe dupes in the DB browser, right? or was it just the 9000 that confused you?) |
| 12:34:37 | GigaBrick | No, I definitely saw the dupes in the database |
| 12:34:49 | GigaBrick | But I think the playlist thing is unreleated since I just found the filesystem dirty |
| 12:34:57 | sideral | alright |
| 12:35:17 | JacekNiesobski | can I ask to be added to the WikiUsersGroup? |
| 12:36:33 | sideral | GigaBrick: Slasheri and I have a theory about the dupe issue (double commit into a dirty database). I now have a filesystem copy from someone who ran into it (and also FS #12228, which may be related), and hope to be able to reproduce the issue now. |

| 12:38:01 | FBI_Guy | Llorean: sorry for late response :P, but i mean is there a way to copy the replaygain metadata so i dont have to replace the songs i already have on my player which dont have replaygain info with the ones from my computer which now do |
| 12:38:08 | sideral | GigaBrick: But if you have a recipe for reproducing it, I'd still be grateful if you posted it to FS #12129 |

| 12:38:47 | GigaBrick | Okay, will do if it happens again |
| 12:38:50 | sideral | that is, all /.rockbox/database*.* files |
| 12:39:02 | sideral | cool, thanks! |
| 12:39:20 | GigaBrick | Yeah, this time was so mixed with other things I'm not really sure it'd be any help to recall exactly what happened |
| 12:39:42 | GigaBrick | Or if I really could |
| 12:39:52 | sideral | Slasheri: Have you seen the dircache-related "crazy idea" session I tortured everyone with two nights ago? |
| 12:40:34 | GigaBrick | I think I read through that |
| 12:40:39 | GigaBrick | Please don't nix the db, <3 the db |
| 12:41:01 | sideral | Slasheri: Might be an entertaining read: http://www.rockbox.org/irc/log-20110816#00:01:31 |
| 12:41:37 | Slasheri | sideral: hehe, i read that =) |
| 12:42:54 | Slasheri | sideral: in fact, i thought about block cache implementation before implementing the dircache :) |
| 12:43:13 | sideral | GigaBrick: No one plans to remove it, no worries :) |
| 12:43:45 | GigaBrick | Heh, okay, just had to get that out there since there doesn't seem to be a lot of love for it |
| 12:44:15 | sideral | Yeah, it's probably the best solution. I do worry about the complexity of its interface for clients, though, especially when the dircache shuts down |
| 12:45:14 | sideral | Perhaps an alternative idea would be to hide the dircache behind the filesystem interface and just offer an interface for retrieving the filename of an "inode" (aka dircache ID) |

| 12:47:34 | GigaBrick | Just reproduced the db duplication I had earlier |
| 12:48:39 | sideral | GigaBrick: dang, there goes my after-lunch nap ;) |
| 12:48:48 | GigaBrick | Disconnected USB, had the "Error accessing playlist control file" splash, tried to resume again anyway, got "Invalid control file" splash so then I went to load a new playlist and got "Error updating control playlist" and the player hung up hard |
| 12:48:53 | GigaBrick | Would not retrun to main menu or even power down |
| 12:48:56 | GigaBrick | So I had to flip the battery |
| 12:49:04 | | Quit Rob2222 (Ping timeout: 252 seconds) |
| 12:49:06 | GigaBrick | Loaded the device on usb and checked my filesystem to make sure that wasn't it again |
| 12:49:23 | GigaBrick | Filsystem was clean, so I started it again, the playlist contro file loaded the playlist I had just tried and started playing |
| 12:49:26 | Llorean | FBI_Guy: Whatever tool scanned them on your PC should also be able to scan them on your player. |
| 12:49:30 | GigaBrick | But then when I went to check the database, duplicates |
| 12:49:45 | GigaBrick | One thing I noticed that when it was hung, the disk was doing an awful lot |
| 12:50:07 | FBI_Guy | Llorean: yeah but that takes forever :P (sorry if this is the wrong place ro be asking) |
| 12:50:50 | sideral | GigaBrick: OK, please add a comment containing the steps and a copy of your DB to the tracker task |
| 12:51:07 | GigaBrick | Okay |
| 12:51:10 | Llorean | FBI_Guy: Typically tagging tools are not designed to identify duplicate songs and match the tags between them. So you'll either need to copy them over, or re-scan |
| 12:51:13 | sideral | ah, before you shut down |
| 12:51:35 | sideral | can you check in the FS browser whether everything looks OK? |
| 12:51:36 | GigaBrick | Yeah, I've got the .rockbox dir open |
| 12:52:09 | FBI_Guy | Llorean: alright, thanks, I guess ill just scan again |
| 12:53:11 | sideral | GigaBrick: enable "view all" in the file browser, and look out for strange file or dir names in the root directory |

| 12:53:44 | GigaBrick | Everything looks right |
| 12:54:04 | sideral | OK, that rules out the dircache corruption issue we've had a few revisions ago |
| 12:54:26 | sideral | which could lead to loops in the dir hierarchy, which in turn lead to duplicates |
| 12:54:42 | GigaBrick | Hmm, interesting.... |
| 12:54:49 | GigaBrick | I copied my db before checking the files |
| 12:54:57 | GigaBrick | SO when I disconnected I got "Error accessing playlist control file" again |
| 12:55:15 | GigaBrick | I thought I'd try to reproduce the whole thing again just for kicks and loaded a playlist, but it worked fine this time |
| 12:55:32 | GigaBrick | Only difference I can see is that before I inserted the USB while music was playing, this time it was inserted from the main menuy |
| 12:55:34 | | Quit metaphys (Quit: CGI:IRC (Ping timeout)) |
| 12:55:36 | GigaBrick | -y |
| 12:56:35 | sideral | that's probably an unrelated issue, but worth mentioning in the FS comment anyway |
| 12:56:52 | GigaBrick | Yeah |
| 12:56:56 | sideral | Maybe you should report a separate bug for this behavior as well |
| 12:57:06 | GigaBrick | In fact I ran into the duplication while trying to figure out why the playlist control file was doing that |
| 12:57:18 | GigaBrick | I know it's related to a panic that gevaerts fixed |
| 12:57:47 | GigaBrick | Had to add a 100 ms delay before the disk mounted again after leaving usb mode, or else it would panic because nothing was mounted |
| 12:58:02 | GigaBrick | Well, the only times I get the "Error accessing control playlist file" are times that it would otherwise panic without that sleep |
| 12:58:08 | GigaBrick | So there's something else going on there |
| 12:58:35 | sideral | sound like kind of a crude workaround |
| 12:59:02 | GigaBrick | Heh, can't comment, it stops it from panic'ing at least |
| 12:59:27 | GigaBrick | But I think a similar thing is happening where the playlist is trying to be resumed but there's problems acessing the disk |
| 13:00 |
| 13:00:01 | GigaBrick | Mainly basing that off the fact that I only get the playlist control access error on disconnects that would have caused the panic, so it seems fairly related |
| 13:01:19 | * | sideral need to go offline now |
| 13:01:27 | sideral | I'll check FS later |
| 13:01:39 | sideral | thanks GigaBrick for helping to nail this one down! |
| 13:01:57 | GigaBrick | Np |
| 13:02:04 | GigaBrick | You still want me to add those steps I took to the FS right? |

| 13:29:10 | GigaBrick | kugel, I'm going to try reverting to my 30295 build and apply the scrobble patch and see if I still get this behavior, does that sound like it will be helpful at all in determining what might be causing it? |
| 13:29:20 | kugel | GigaBrick: does this happen automatically or do you try tor esume playback? |

| 13:50:34 | GigaBrick | But most of the time I have a dynamic playlist |
| 13:50:41 | kugel | I see a possible code path for your problem |
| 13:51:00 | GigaBrick | Does it still apply if I get this behavior when using dynamic playlists too? |
| 13:51:05 | kugel | can you repro this with a dynamic playlist? |
| 13:51:28 | pamaury | gevaerts: I thought we had a define for player with no high speed usb |
| 13:51:42 | GigaBrick | kugel, yeah, happens with either type |
| 13:52:24 | pamaury | I found USB_NO_HIGH_SPEED but it seems to be unused |
| 13:52:45 | kugel | GigaBrick: can you check if the playlist control thread is active (in view OS stacks debug menu)? |
| 13:53:09 | GigaBrick | After I repro or just right now? |
| 13:53:17 | gevaerts | pamaury: yes, I don't think there's more. That was basically debug code |
| 13:53:38 | pamaury | so all players have high speed usb or hardware usb bridge ? |
| 13:54:08 | gevaerts | As far as I know, yes |
| 13:54:16 | gevaerts | Well, up to now anyway |
| 13:54:31 | kugel | GigaBrick: after you repro |
| 13:54:35 | gevaerts | Do we care actually, outside of the driver? |
| 13:55:00 | GigaBrick | Okay, I'll have to put the current revision back on |
| 13:55:20 | pamaury | gevaerts: in the core, for the descriptors |
| 13:55:47 | pamaury | we report as 1.1 usb when we don't have high speed |
| 13:55:58 | pamaury | but that's not mandatory iirc |
| 13:56:09 | gevaerts | Ah, yes, the other speed config |
| 13:56:57 | *** | Saving seen data "./dancer.seen" |
| 13:57:28 | gevaerts | I'd say this is something to do when we actually have a target where it matters |
| 13:58:19 | pamaury | I have a FS only device |
| 13:58:29 | gevaerts | Ah, you have some work to do then :) |
| 13:59:05 | pamaury | I'm not sure what needs to change,the only use of USB_NO_HIGH_SPEED us the bcdUSB field andI think you can report 2.00 for a FS device |
| 13:59:55 | gevaerts | I'm not sure either. This is a *long* time ago... |
| 14:00 |
| 14:00:31 | pamaury | found: If a full-speed only device (with a device descriptor version number equal to 0200H) receives a |
| 14:00:31 | pamaury | GetDescriptor() request for a device_qualifier, it must respond with a request error. The host must not make |
| 14:00:31 | pamaury | a request for an other_speed_configuration descriptor unless it first successfully retrieves the |
| 14:00:31 | DBUG | Enqueued KICK pamaury |
| 14:00:31 | pamaury | device_qualifier descriptor. |
| 14:01:00 | gevaerts | right, I think we don't do that yet |
| 14:01:21 | gevaerts | I suspect that's all there is to it |
| 14:03:19 | pamaury | so in fact we could probably keep the current code, assume the host don't request device_qualifier and always use 2.00 version. In fact there is not need to disctinction |
| 14:07:00 | pamaury | Except for packet size: bulk is 64 at FS |
| 14:07:19 | pamaury | but that's already handled anyway |
| 14:08:21 | GigaBrick | kugel, I got the "Erorr accessing playlist control file" to reproduce |
| 14:08:33 | GigaBrick | Checked the playlistcachectrl thread and didn't see much of anything |
| 14:08:41 | GigaBrick | Changed from T to something, but went so fast I didn't see what it changed to |
| 14:12:42 | GigaBrick | Weird, now it's showing the splash while the playlist is actually playing on the WPS screen |
| 14:12:51 | GigaBrick | And now it's showing it in the debug menu when I went to check on that thread |
| 14:13:19 | GigaBrick | Except now it's doing something weird where it shows up briefly and disappears... :/ |
| 14:14:02 | gevaerts | pamaury: the host will ask for the device_qualifier. If it does, though, the worst that happens is that windows tells you that a different port might be faster. Returning an error there (for FS-only devices) is probably a good idea in the long term |
| 14:16:23 | pamaury | okay, I'll do that |

| 14:24:20 | GigaBrick | No, should I? |
| 14:25:02 | kugel | you can try |
| 14:25:29 | GigaBrick | Okay, I'll reboot and give it a try too |
| 14:26:20 | GigaBrick | Yeah, seems to eliminate that splash when dir cache is off |
| 14:26:45 | kugel | :\ |
| 14:27:01 | kugel | thanks for your debugging, I'll have a look later |
| 14:27:37 | GigaBrick | Also, I thought I should mention |
| 14:27:56 | GigaBrick | I applied the sleep patch and the scrobbler patch to 30307 |
| 14:27:58 | kugel | the playlist control thread tries to fetch dircache ids in the background for the filenames, that seems to fail |
| 14:28:05 | GigaBrick | STill got the playlist splash |
| 14:28:10 | GigaBrick | But for some reason in 30295 I don't |
| 14:28:17 | kugel | oh interesting |
| 14:29:22 | GigaBrick | Yeah, I haven't seen what's the highest revision I can go to yet without reproducing, but I figured I'd try that and that might answer something |
| 14:29:27 | kugel | not sure what commit can cause that then |
| 14:30:07 | kugel | you did try bumping the sleep time higher in the sleep patch, didn't you? |
| 14:30:22 | GigaBrick | Yeah, I had it up to a full second and it didn't make a difference |
| 14:30:27 | GigaBrick | Didn't know if I should try any higher though |
| 14:30:39 | GigaBrick | Well, a full HZ (I'm assuming that's a second) |
| 14:31:26 | kugel | that's a second yes |
| 14:31:56 | GigaBrick | Hertz is rolling in his grave at my unsuredness. :P |
| 14:32:52 | GigaBrick | Anyway, I suppose I can go up the revisions incrementally from 30295 until I find which one starts reproducing the behavior |
| 14:33:06 | kugel | that would be fine :) |
| 14:33:46 | GigaBrick | Oh, one quesiton about svn updating |
| 14:33:57 | GigaBrick | How can I get it to actually replace a file that has custom modifications? |
| 14:34:35 | kugel | not at all |
| 14:34:40 | kugel | you need to undo the modifications |
| 14:34:47 | GigaBrick | Oh, all right |
| 14:34:49 | kugel | e.g. svn revert |
| 14:35:22 | GigaBrick | Oh, come to think of it, is there a way to revert back to a specific revision? |
| 14:35:32 | GigaBrick | I should probably just man svn... |
| 14:35:56 | kugel | svn up -rXXXX |
| 14:37:31 | GigaBrick | Oh, cool, it takes care of the changed files too |

| 22:23:27 | Buschel | is this for IRAM? |
| 22:23:30 | wodz | dram |
| 22:24:15 | wodz | iram is (almost) useless as it is 4kB or so |
| 22:24:20 | Buschel | S5L8701 DRAM = 59 read, 35 write, 35 set, 22 copy |
| 22:24:43 | Buschel | your numbers are similar to S5L8701 IRAM |
| 22:25:42 | bertrik | Buschel, maybe it's just misconfigured then? |
| 22:25:54 | Buschel | yep, maybe... |
| 22:26:10 | wodz | hmm, so why mp3 decoding takes so much may it be (extremely) slow lcd updates? |
| 22:27:08 | Buschel | on S5L8701 I can sqeeze a bit more performance from my nano 2G. but this might most likely impact other nano's... for the rk27xx it might be interesting to check the RAM timings |
| 22:28:05 | Buschel | wodz, if the memory is that slow the filterbank will be slow as well. I think the codec measurement is fine |
| 22:28:56 | Buschel | wodz, I bet you'll see similar results if you do not update the screen during the test_codec run |
| 22:29:36 | wodz | you said s5l8701 dram read 59 vs. rk27xx dram read 100 - I don't get |
| 22:30:49 | Buschel | most codecs use IRAM for the performance critical parts. IRAM S5L8701 = 107 read, 80 write/set, 45 copy |

| 22:48:07 | wodz | I think so |
| 22:48:21 | wodz | and APB is Fcpu/4 |

| 22:51:29 | | Quit dunkaist (Quit: leaving) |
| 22:51:52 | Buschel | you might for example run test_codec with CPU and AHB at 133 MHz |

| 22:53:13 | wodz | no |
| 22:54:34 | Buschel | you will most likely see that test_codec will result in higher efficiency when CPU:AHB = 1:1. this way the CPU could be clocked to lets say 50 MHZ and be able to play mp3 in realtime. |
