| 01:20:55 | steeven | hi! |
| 01:21:31 | steeven | I've read a lot about rockbox but I'm having trouble figuring something out |
| 01:23:20 | kkurbjun | what's the trouble? |
| 01:23:55 | steeven | with rockbox on a capable fifth generation+ ipod, will the device lose the ability to send digital audio to a car audio receiver? |
| 01:24:58 | steeven | I can't really find much information on this |
| 01:24:59 | kkurbjun | that depends, you can always boot back into the apple firmware, rockbox supports some accessories, but I can't say for sure whether your receiver will work |
| 01:26:01 | steeven | well, some receivers have the capability to control an ipod and play audio from it using the receiver's own DAC |
| 01:28:14 | kkurbjun | You might try looking at the ipod accessory page in the wiki, I'm not really sure if it would work in rockbox or not, but if it doesn't you can always go back to the apple firmware |
| 01:28:35 | kkurbjun | you just hold the menu button I believe while it is booting to go back to the apple software |
| 01:29:26 | steeven | well, the problem is I don't have an ipod or an ipod-compatible receiver |
| 01:30:08 | steeven | I'm only interested in getting them if I can easily play lossless audio sent to the receiver digitally |
| 01:30:13 | BryanJacobs | steeven: is "digital audio" all that important? |
| 01:30:44 | BryanJacobs | you could just use the line out - the cable you'd be using is only a few feet long tops |
| 01:30:54 | steeven | sure is, no portable music player has a DAC designed to power an enthusiast audio system |
| 01:31:10 | steeven | the problem is the line out is designed for headphones |
| 01:31:16 | BryanJacobs | you don't have an amp in an "enthusiast" system? |
| 01:31:28 | | Quit Thundercloud (Remote closed the connection) |
| 01:31:29 | BryanJacobs | no, the line out is not designed for headphones |
| 01:31:37 | BryanJacobs | line out is preamped DAC output |
| 01:32:19 | scorche | steeven: many a device's DAC is just fine...you are either thinking of the amp, or you are misinformed |
| 01:32:39 | steeven | the line out? is there some kind of adapter cable that gives you that connection on an ipod? |

| 01:33:57 | steeven | well like I said, I don't have an ipod yet ;) |
| 01:34:21 | steeven | where can i find out the voltage of this connector? |
| 01:34:35 | BryanJacobs | steeven: not sure you understand the problem |

| 01:35:03 | scorche | steeven: most of the headunits you are talking about either communicate with the ipod through what we call advanced features of the apple accessory protocol (which we havent implemented yet, though more simple AAP bits work), or simply use the DAP as a portable hard drive and just read the files off it |
| 01:35:48 | BryanJacobs | steeven: what I was talking about is a system with an "aux in" jack to which you may connect the ipod's line out; such a system has its own amplifier and so the input voltage doesn't matter. |
| 01:36:30 | | Quit timc (Remote closed the connection) |
| 01:36:37 | | Quit Thundercloud (Remote closed the connection) |
| 01:37:17 | steeven | so I should just disregard the fact that the system is designed for 2V aux inputs and pretend like giving it a 200mV signal is going to be close to adequate? |
| 01:38:19 | BryanJacobs | you're saying your amp has a *minimum* input? |
| 01:38:43 | BryanJacobs | it's not powered? |
| 01:39:09 | steeven | I'm saying it has a specific sensitivity to input and thus has an optimal input range |
| 01:39:47 | steeven | hehe, maybe the connector is exactly what I need. I'm not saying it isn't |
| 01:40:11 | steeven | it's kind of odd that the manufacturer doesn't specify this on their website though |
| 01:41:06 | BryanJacobs | to answer your original question: if your system has an iPod connector which uses the DAP as a UMS device, then rockbox will work fine. If it has a connector using the AAP, Rockbox probably won't work yet. If it has an aux in, you MIGHT <I'm skeptical> need a preamp but it will work |
| 01:42:00 | steeven | keep in mind that if it's extremely low voltage it will be more susceptible to noise from the mess of cables it'll be required to run next to |
| 01:42:16 | steeven | well, that's helpful, thank you |
| 01:42:25 | BryanJacobs | steeven: no problem |
| 01:42:28 | steeven | is AAP support something that's being actively developed? |
| 01:43:07 | scorche | as i said, simple functionality of the AAP has been implemented...advanced features havent been |
| 01:43:07 | steeven | it's seeing quite widespread adoption in automotive audio systems |

| 01:44:54 | BryanJacobs | steeven: hmm, says it requires an FAT iPod |
| 01:45:28 | steeven | the frustrating part is the fact that the receiver can decode ALAC from an iPod, but *not* from a usb mass storage device (which can be directly plugged into the unit) |
| 01:46:02 | scorche | steeven: that says to me that it uses the advanced features of AAP (wont work with rockbox), but will also read the files from the hard drive (will work) |
| 01:46:13 | MT | linuxstb : sorry, tried a little with sox play but can't play the raw decoded data. |
| 01:47:00 | steeven | in that case I'd be much better off with a 1.5tb hard drive, an enclosure, and a 12v power supply with inline surge suppressor |
| 01:47:00 | Unhelpful | caring about the format makes me think MSC |
| 01:47:02 | MT | I converted it to wav using sox and then played the output file. |
| 01:47:23 | steeven | I could get two for the price of an iPod, heh |
| 01:47:38 | BryanJacobs | steeven: this receiver has three modes, see page 16 of the manual |
| 01:47:59 | steeven | checking |
| 01:48:13 | MT | linuxstb : but it's just rubbish, so I want to try playing the decoded data directly without conversion .. |
| 01:50:19 | steeven | BryanJacobs: the depressing part is that it doesn't say it can decode ALAC from any input besides an iPod |
| 01:50:47 | BryanJacobs | steeven: it doesn't say it can do ALAC at all |
| 01:51:17 | BryanJacobs | steeven: and it explicitly says it does NOT support WMA lossless |

| 02:48:31 | Unhelpful | Traveler2: i'd expect you do that by *trying* to read another line. |
| 02:48:55 | BryanJacobs | Traveler2: and that answers your first question :-) |
| 02:50:52 | Traveler2 | so, does read_line return -1 if there isn't another line? |

| 03:00:42 | kugel | !read_line* |
| 03:00:59 | kugel | <= ? |
| 03:01:22 | BryanJacobs | <= 0 catches the "I read 0 bytes because nothing's left" and the "there's an error" cases |
| 03:01:41 | * | BryanJacobs assumes the file has no blank lines |
| 03:02:05 | kugel | if it's 0, it already reached EOF before that call, which possibly means your check was unsufficient in the call before :) |
| 03:02:42 | EternalRains | In WPS, is the Shuffle (%ps) conditional always set when the Repeat mode (%mm) is set to shuffle? |
| 03:02:52 | BryanJacobs | kugel: <shrug> any time the call returns >0 you may use the result |

| 06:44:28 | robin0800 | Llorean: Would this also apply to c200 |

| 07:00 |
| 07:01:28 | robin0800 | tmzt: I you certain its right for the c200 because The OF works |
| 07:02:28 | tmzt | the OF works because MTP is enabled I assume, rockbox does not currently support MTP/PTP |

| 07:03:49 | tmzt | you can check the hal logs but this is really a ubuntu problem |
| 07:04:45 | tmzt | The USB product ID used by Sansa e200 running in UMS/MSC mode, both by Rockbox as well as original firmware is 0x7421. The PID for MTP mode is 0x7420 |
| 07:05:06 | tmzt | which does lsusb report in rockbox? |
| 07:06:55 | tmzt | and what does it report in OF |
| 07:11:54 | robin0800 | tmzt: Yes I'm at work at present but now I know what might be wrong I'll check and report back later today I think when it dosn't connect lsusb can't read it |
| 07:12:56 | robin0800 | tmzt: I have two now C240's |
| 07:13:15 | tmzt | even if libusb is using it should show in lsusb, if not that's probably a different problem |
| 07:13:56 | tmzt | the patch doesn't exactly make sense either, it doesn't seem like it should affect mass storage mode since that uses a different vend/prod |
| 07:15:03 | robin0800 | I think in E200's case the usb id's are wrong in ubuntu |

| 08:15:55 | Unhelpful | all i need now, i think, is replacements for the bitstream functions, and to clone most of jpeg_decode into a function that does one row at a time. what did you think of the idea of a scaler callback that fetches from the in-memory yuv bitmap? the downside is that it would be scaling on draw, but that's probably not fixable if you want the decoded cache as yuv anyway... also, is the Y-only decoded image on greyscale/mono targets 8 bits? |

| 08:35:36 | amiconn | Each decoded component is a canonical 8-bit bitmap. The jpeg viewer feeds the Y component directly to grey_ub_gray_bitmap_part() |

| 08:37:22 | | Join B4gder [241] (n=daniel@rockbox/developer/bagder) |
| 08:37:44 | amiconn | The jpeg viewer keeps both the compressed data and several decoded zoom levels in memory, as YUV for space reasons (non-subsampled YUV would take the same amount of memory as RGB, subsampled YUV then saves) |
| 08:38:31 | Unhelpful | for greyscale targets, basically you need a context struct that knows what line is being read from, and fills a struct img_part in with the address of the start of the row, and the length. |
| 08:39:00 | Unhelpful | ...and *a function that* fills etc :) |
| 08:40:20 | amiconn | Otoh, storing native bitmaps on colour targets (RGB565, RGB565swapped) would save space vs. YUV 4:4:4, and would be on par for YUV 4:2:2. It would need a little more vs. YUV 4:2:0 |
| 08:40:30 | | Join l403 [0] (n=l@85.132.159.239) |
| 08:41:08 | Unhelpful | for color targets, things are more complicated. the color scaler only understands rgb, so the callback needs to fill a buffer with rgb pixels and return a pointer to a struct img_part with the appropriate data. the buffer can be whatever size is convenient, provided the returned buffer never crosses a line end |

| 08:59:58 | Unhelpful | right... that's a slightly tricky part, but i think that the getc/putc functions i wrote for reading in characters, and the rework i'm going to have to do for the bitstream stuff, could be set up so that they can be conditionally replaced with versions that just fetch the data from memory. most of the code could be shared, then, but the core jpeg loader wouldn't need to be extended for reading from a file in memory, and plugins that wan |
| 08:59:59 | Unhelpful | t to decode from memory would have to call a version built for pluginlib. |
| 09:00 |
| 09:02:42 | Unhelpful | or, the core version could take function pointers for getc/putc and friends, but that seems like it would be bloating and slowing down the core version (via checking pointers before calling those functions, or having to call its versions via pointers) for something that only plugins would be using. |
| 09:03:19 | amiconn | Accessing single bytes doesn't sound very efficient |
| 09:04:52 | Unhelpful | most of the header data is byte-oriented, though. the getc/putc i wrote load 16B at a time into a buffer so that we're not constantly doing 1B calls to read. |

| 15:05:40 | Llorean | If it treats us differently based on them when we're claiming to be an MSC device, the host has broken behaviour |
| 15:06:42 | GodEater | robin0800: the problem is gnome is basing it's decision about whether the device is MSC/MTP on the USB ids - which it shouldn't - it should listen to what the device is saying it supports. |
| 15:07:29 | robin0800 | Llorean: Have we the right USB Id's To tell it itts MSC then |
| 15:07:47 | GodEater | robin0800: you're not listening, it's NOTHING to do with the USB id |
| 15:07:48 | Llorean | robin0800: The USB IDs have nothing to do with telling it it's MSC. |
| 15:08:51 | Llorean | We are telling it our device is MSC. It's ignoring this because it's using the USB IDs for something they're not meant to be used for, instead. |

| 16:53:46 | linuxstb | MT: I don't think that will tell you anything - you want to compare the data at earlier stages, not just the final output. |
| 16:54:04 | linuxstb | So the first thing would be the input into the decoder. |
| 16:54:11 | linuxstb | And then later stages... |
| 16:55:45 | saratoga | MT: I would output WAV when debugging WMA after it was mostly working (so that I could import into matlab easily for plotting) |
| 16:56:15 | saratoga | initially, I defined a lot of "dbprintf()" macros that could be turned on and off to print debug info |
| 16:56:29 | saratoga | i had one that dumped the IMDCT data, another that dumped during quantization, etc |
| 16:56:50 | saratoga | i put them in the same places in the integer and fp codecs so I could compare what was going on |

| 17:02:37 | saratoga | I would compare it to the original ffmpeg codec at the same point in the code |
| 17:03:05 | saratoga | ideally both codecs should give the same output (converting fixed to fp if needed) |
| 17:03:24 | saratoga | particularly at this early stage where you have not optimized anything yet |
| 17:05:25 | MT | so I'd add debugging lines to cook decoder in ffmpeg and write a main() that uses this decoder with same file ? |
| 17:05:56 | saratoga | thats one way to do it |
| 17:06:07 | saratoga | you could also recompile ffmpeg, though that might be a bit slow |

| 17:13:30 | MT | not much .. it now uses rb's rand() instead of ffmpeg'srandom_seed() and it no longer needs AVCodecContext/AVFormatContext/AVPacket .. instead, it uses RMContext and RMPacket |
| 17:14:27 | | Quit toffe82 (Read error: 104 (Connection reset by peer)) |
| 17:15:34 | saratoga | could you keep an unmodified version of cook.c handy and compare to that? or do you need to change too much to get it to work with your parser? |
| 17:16:10 | | Join toffe82 [0] (n=chatzill@74.0.180.178) |
| 17:16:34 | saratoga | i should also ask if you got your parser to play an RM file before you started removing ffmpeg junk? |
| 17:16:37 | MT | I can't use an unmodified version with my parser currently if that's what you mean. |
| 17:17:28 | saratoga | ah ok |
| 17:17:35 | MT | play an RM file ? |
| 17:18:07 | saratoga | i was wondering if you were able to take the output from your parser and feed it to the ffmpeg decoder and get correct PCM audio |
| 17:18:18 | saratoga | but it sounds like you're not there yet |
| 17:18:39 | MT | I did something similar .. |
| 17:18:48 | MT | not playing audio though |
| 17:19:34 | saratoga | sorry I mean just writing it to a file so you can compare it to ffmpeg |
| 17:20:11 | MT | ffmpeg has a command which produces the descrambled cook audio frames that should be fed directly to the decode() function .. I made the parser output the same set of file, cat'd both outputs into 2 different files and diff'd them against each other |
| 17:20:49 | saratoga | ah ok |
| 17:21:03 | saratoga | but you don't have cook.c compiling outside of ffmpeg then? |
| 17:21:58 | MT | I've isolated cook.c from ffmpeg before working with it. |
| 17:22:15 | MT | so it's compiling outside of ffmpeg |
| 17:22:40 | MT | is that what you mean ? |
| 17:23:18 | saratoga | MT: does the parser give the same output when you diff ? |
| 17:23:26 | MT | yes |
| 17:23:41 | saratoga | but you can't decode an RM file? |
| 17:25:15 | | Quit bubsy ("Mrrrrreow!") |
| 17:26:15 | MT | I can *use* the decode function of cook.c and produce a decoded output.. the duration is correct, but it sounds horrible (mainly noise, no identifiable audio/music..) so it seems like there's something wrong with the decoding part. |
| 17:26:26 | saratoga | ah ok |
| 17:26:31 | saratoga | i misunderstood you before |
| 17:26:44 | saratoga | i'll be back in a few minutes, I need to help someone with something |

| 18:26:28 | MT | linuxstb : quick question because I have to go in a few minutes ; to use cook.c directly from ffmpeg means that I'll have to know how to initialize AV* stuff. Or can I just hard code COOKContext with the same values with which it's init'ed in my decoder, then I won't need any ffmpeg-specific stuff ? |
| 18:26:36 | | Quit Guest27896 (Read error: 110 (Connection timed out)) |

| 18:46:27 | schrottplatz | of my rockbox |
| 18:46:54 | MT | To avoid using cook_decode_init() ( and dealing with ffmpeg's parser, stream reader, codec context .. etc) I could initialize COOKContext with the same values from my code , and for cook_decode_frame() I could just send the audio frames that are output by my parser or ffmpeg's .. would this be a correct approach ? |

| 18:49:15 | schrottplatz | i think we should have as the first entry |
| 18:49:21 | schrottplatz | musik |
| 18:49:31 | schrottplatz | instead of files |
| 18:49:34 | gevaerts | why? |
| 18:49:37 | schrottplatz | *music |
| 18:49:49 | evilnick_7 | But that doesn't list ONLY music. It lists Files |
| 18:50:00 | LambdaCalculus37 | It's a file browser, hence the name. |
| 18:50:08 | schrottplatz | and under music the first option resume playback and second database |
| 18:50:09 | LambdaCalculus37 | People carry more than music on their players. |
| 18:50:40 | schrottplatz | so when i start my player |
| 18:50:47 | schrottplatz | i can navigate in my pocket |
| 18:50:48 | bertrik | I can see the point |
| 18:50:56 | gevaerts | schrottplatz: please try to keep thoughts on single lines |
| 18:51:00 | schrottplatz | ok |
| 18:51:09 | * | gevaerts mostly listens to non-music, and he doesn't use the database |
| 18:51:12 | evilnick_7 | schrottplatz: That means that it'd be two button presses and also movement in the menu to resume music |
| 18:51:27 | schrottplatz | yes |
| 18:52:17 | schrottplatz | and things like system and settings should be one entry |
| 18:52:33 | schrottplatz | btw playlist in the music list too |
| 18:53:04 | linuxstb | MT: Sorry, I don't have time to look at it in detail now. But your idea sounds sensible - to just initialise CookContext yourself. |
| 18:53:37 | LambdaCalculus37 | schrottplatz: That doesn't sound very intuitive at all, to be honest. |
| 18:53:56 | schrottplatz | maybe second entry in the main menu would be files (bc i cant browse trough the files in my pocket) |
| 18:54:15 | gevaerts | It should at least be called "audio", *not* "music |
| 18:54:26 | schrottplatz | yes |
| 18:54:27 | schrottplatz | ok |
| 18:54:44 | gevaerts | schrottplatz: can you browse the database in your pocket? |
| 18:54:47 | evilnick_7 | I do like the idea of having "Music" as an entry on the main menu. That's what most users would want to access most often (imho) |
| 18:54:52 | schrottplatz | no |
| 18:54:57 | MT | linuxstb : no need to look in detail, just wanted to know what you thought about this approach. Thanks. |
| 18:55:07 | schrottplatz | but i want to have same things in the same menu |
| 18:55:08 | gevaerts | so why does that make Files different? |
| 18:56:31 | schrottplatz | gevaerts: understood? |
| 18:57:13 | gevaerts | I still don't see why (a) the pocket thing is relevant, and (b) how your proposal would make things easier |
| 18:57:39 | schrottplatz | its more quick to navigate |
| 18:57:52 | gevaerts | is it? |
| 18:57:54 | | Quit MT (Read error: 104 (Connection reset by peer)) |
| 18:58:09 | schrottplatz | in my case yes |
| 18:58:20 | schrottplatz | i dont know your flow |

| 18:59:01 | schrottplatz | and where is your problem? |
| 18:59:14 | gevaerts | I don't have a problem. The current layout is fine |
| 18:59:38 | * | LambdaCalculus37 agrees with gevaerts |
| 18:59:57 | LambdaCalculus37 | I don't use the database, either, except for PictureFlow. |
| 19:00 |
| 19:00:19 | schrottplatz | hmm |
| 19:00:54 | gevaerts | the database is the second entry. Surely that's not far to reach? |

| 19:01:52 | linuxstb | schrottplatz: I don't think you're going to convince us to change the official menu structure. But if you can compile Rockbox yourself, it's easy enough to move menu items around and rename them. |
| 19:02:10 | schrottplatz | i think it would make more sense if there would be an entry with audio->resume playback; database; (later picture flow) |
| 19:02:49 | gevaerts | and why not files? |
| 19:02:55 | schrottplatz | linuxstb: i just wanted to make suggestions... |
| 19:03:22 | schrottplatz | gevaerts: in this case then only music files |
| 19:03:30 | evilnick_7 | schrottplatz: If there's a good enough reason to change (that will be beneficial for enough users) then we're open to suggestions. They would have to offer improvements to enough people though and not just for your use individually. |
| 19:03:46 | schrottplatz | for example a folder /music/ |
| 19:03:53 | gevaerts | schrottplatz: my personal opinion is that what you propose would make rockbox slower and harder to use |
| 19:04:02 | gevaerts | Also a lot less flexible |
| 19:05:02 | gevaerts | Why do you e.g. want to restrict where users can put audio files? |
| 19:05:04 | bertrik | schrottplatz, I think the problem with something like the main menu structure is that there's probably a lot of people having some kind of strong feeling about it, so changing it is a very time-consuming process. |

| 19:07:25 | Llor_Phone | schrottplatz: the best way to get something like that changed is to write a patch. |
| 19:07:53 | schrottplatz | but im to stupid to write a patch :) |
| 19:07:55 | gevaerts | The big problem is that it's easy to assume that the way you're using it is the most natural way and that everyone will agree. In reality there is no best way, and everyone does something different. Everyone falls into that trap... |
| 19:08:04 | Llor_Phone | The current menu is there for a reason. You basically need to show your way is better with a patch people can use over time to compare |
| 19:09:08 | bertrik | Does the database store anything other than tags for audio files? If not, couldn't it have a more specific name, like "Audio database"? |
| 19:11:00 | Llor_Phone | bertrik: In the future it may hold other media. RIght now, yes, audio only. |
| 19:11:39 | gevaerts | maybe "media database" would work? |
| 19:12:51 | evilnick_7 | Until anything else is supported then "Audio database" sounds better to me. Once other items are in the db then "Media database" would be more descriptive. |
| 19:12:54 | Llor_Phone | Could, yes. I may have missed something. Was one of the problems a confusing name? |
| 19:13:48 | bertrik | Llor_Phone, sorry, no not really, the other discussion just got me thinking about some of the names used in the main menu |
| 19:14:41 | Llor_Phone | Maybe something more like "Library" |

| 20:25:18 | linuxstb | amiconn: Yes, assuming there are decoders. It depends how long the cook codec takes (the ffmpeg decoder is floating point). |
| 20:25:50 | amiconn | I was looking at this list: http://wiki.multimedia.cx/index.php?title=RealMedia#Audio |
| 20:26:33 | amiconn | For ac3 and aac we already have decoders, so it's "only" handling a different container |
| 20:26:49 | linuxstb | I think ffmpeg has decoders for RealAudio 1.0 and 2.0 as well. |
| 20:27:02 | amiconn | That leaves VSELP, LD-CELP, Sipro and ATRAC as lossy codecs |
| 20:27:14 | linuxstb | And there's an ATRAC codec in ffmpeg too... |
| 20:27:42 | linuxstb | But yes, MT's original proposal talked about writing a general RM demuxer, with cook as the first codec. |
| 20:28:24 | linuxstb | Not on that list is MP3, but the data is packed in a different way to normal mpeg audio streams. |

| 22:29:48 | gevaerts | JdGordon|: deleting the file you're playing is common enough for it to be supported from the WPS context menu :) |
| 22:31:36 | * | Llorean wonders if the WPS context menu should also have "Remove from Playlist" |
| 22:32:21 | JdGordon| | gevaerts: thats been an outstanding bug for a while, imo it shuold be removed |
| 22:32:56 | JdGordon| | remove from playlist makes sense... remove from the disk is just asking for trouble |
| 22:33:49 | Llorean | Remove from disk seems pretty safe too, at least we don't get people really complaining about it. |
| 22:33:54 | evilnick_7 | Llorean: I'd like to see that personally |
| 22:34:04 | Llorean | But it seems to me there should be "Remove from Playlist" and "Remove from Disk and Playlist" |
| 22:34:27 | Llorean | The one option we do have is, I think, the least useful variant since it ought to be very uncommon that you want it gone from the disk, but still in the playlist simply getting skipped over |
| 22:34:50 | *** | Saving seen data "./dancer.seen" |
| 22:34:59 | JdGordon| | Llorean: remove from disk is not safe at all... best case is its fully buffered so you can skip around inside the track without problems... thats lamost never the case though |
| 22:35:21 | evilnick_7 | I find it useful to "preview" new albums and delete the songs I don't want to keep with me on the player when away from a computer. |
| 22:35:45 | gevaerts | I used to delete files from the WPS after listening to them. I suspected some problems at some point (like skipping to the next track being confused), but those were fixed |
| 22:36:11 | Llorean | JdGordon|: If it removed it from the playlist as well (which would include moving on to the next track) it wouldn't be a problem though |

| 22:43:44 | saratoga | Bagder: i spoke with my network admin, and he says that on the 18th the build script tried to initiate more then 200 connections in one hour, and was blacklisted again |
| 22:44:13 | saratoga | do you have any idea how difficult it would be to make the system connect less frequently? |
| 22:45:58 | | Quit JdGordon| ("http://www.mibbit.com ajax IRC Client") |
| 22:46:51 | Bagder | well, we'd have to change the build system to keep the initial ssh connection up |
| 22:47:26 | saratoga | how often does it reconnect now? i've just started reading the code |
| 22:47:31 | Bagder | it's not really that hard, only a bit sensitive area since breaking that script breaks all builds |
| 22:47:50 | Bagder | for each build, it does: |
| 22:48:13 | Bagder | build, copy, cleanup (3 connections) |
| 22:48:40 | Bagder | hm, or is it two copies |
| 22:49:17 | Bagder | yes: build, copy-log, copy-build (for some builds), cleanup |
| 22:49:28 | Bagder | and an initial svn up |
| 22:49:48 | Bagder | so if you build 7 zip-targets, you get 1+7*4 connections |
| 22:50:27 | gevaerts | hm, doesn't modern ssh support multiplexing a connection? |
| 22:50:53 | Bagder | it could just re-use the same one anyway |
| 22:50:59 | gevaerts | Maybe just enabling that and starting a connection to each build server at the start would do the trick? |
| 22:51:06 | Bagder | except for the copy... |
| 22:51:14 | gevaerts | how is that done? scp? |
| 22:51:18 | Bagder | yes |
| 22:56:34 | saratoga | how would you reuse the connection? is there a way to actually control the shell remotely ? |

| 23:00:38 | Bagder | right, man ssh_config has the details too |
| 23:00:52 | gevaerts | you could actually just keep one ssh connection open all the time |
| 23:01:17 | Bagder | one of the trickiest things in the build script is error handling |
| 23:01:34 | Bagder | a connection will not live fine "all the time" ... |
| 23:01:45 | gevaerts | it will if you put it in a loop :) |
| 23:02:08 | gevaerts | but yes, it's not *that* simple |
| 23:02:53 | Bagder | and frankly, there are several things we could improve in the build script as has been mentioned many times |
| 23:02:53 | gevaerts | would this change error handling at all though? I'd expect individual sessions to look the same |

| 23:39:56 | * | bluebrother goes standing in the corner |
| 23:41:29 | gevaerts | tomers: I suspect that RX means OUT. At least in the description for BURSTSIZE and TXFILLTUNING (32.9.5.7 and 32.9.5.8) that seems to be the case, so I'm assuming it's also true for the rest |
| 23:41:56 | gevaerts | darkham: have you checked the wiki and forums? That's where the information lives |

| 23:42:27 | tomers | That means it is from the device point of view... Doesn't the manual apply both for d |

| 23:42:33 | tomers | device and host? |
| 23:43:03 | tomers | Thanks! That really helps. |
| 23:43:37 | gevaerts | tomers: I think RX and TX are probably always from the chip point of view, whether it's host or device |
| 23:44:56 | * | kugel doesn't like bluebrother's proposal size |
