09:36:29[Saint]Well...shit. That's somewhat creepy.

09:42:45Sparkie_I installed rockbox on my 7th gen ipod classic and my battery life is appalling when i have the screen on, 1% every 5 seconds, but it stayed on playing music on shuffle with no display for around 15 hours over night and today. How do i fix the battery life?
09:43:32 Quit JdGordon (Remote host closed the connection)
09:45:25[Saint]The battery indicator is based on voltage, so, its likely your battery is just fucked.
09:45:52Sparkie_should i wipe rockbox and put apple back on and ask for replacement?
09:46:34[Saint]Hahaha. Good luck with that. Its a decade old.
09:46:41[Saint]If not more.
09:48:16Sparkie_oh no i bought it two days ago
09:48:47kugelthe ipod 7th gen is not a decade old
09:49:46kugeland apple still sells it
09:50:07kugelSparkie_: if it's that new the battery is probably fine
09:50:39kugelperhaps the calibration data is just inaccurate
09:50:54[Saint]I don't see how it could be anything other than the battery.
09:51:05[Saint]Its possible to configure it poorly, but, not *that* poorly.
09:51:11kugeldid you try if the "1% every 5 seconds" continues until the battery is completely empty?
09:51:53[Saint]And, yes, the calibration data is bullcrap, but I haven't ever seen the battery on any of my Classics plummet at a rate anywhere close to 1% every 5 seconds.
09:52:03Sparkie_the battery stays on 84% for a while and then at 0% for about 15 minutes with the screen on
09:52:43Sparkie_im thinking it could be to do with the calibration because when it charges it goes really fast then really slow
09:52:53Sparkie_and stays on %'s for a decent amoutn of time
09:52:58[Saint]Even if I configure my Classic as badly as I possibly can, I can't get the batery to drop that fast.
09:53:02Sparkie_oh and it fluctuates
09:53:10[Saint]I set the LCD to always on, and the HDD spindown time to 10 minutes.
09:53:16 Join edhelas [0] (~edhelas@2001:981:e7ba:1:863a:4bff:fe85:8a3c)
09:53:18[Saint]And its still not dropping anywhere near that rate,
09:54:08[Saint]Even other things I can think of that add to it like maxing out all the EQ bands, and enabled accessory power supply don't come close to making the batteyr drop as fast as OP claims his does.
09:54:19[Saint]And my batteries are very well used.
09:54:59kugelSparkie_: i think you should check if it's bad with the OF too
09:55:22[Saint]Hmmmmm...what theme are you using?
09:55:32Sparkie_flying spaghetti monster
09:55:40[Saint]Its highly possible the author fucked up the display.
09:56:03[Saint]Improbable, but, certainly possible.
09:57:07Sparkie_ok i will restore back to apple firmware through i tunes
09:57:40kugelSparkie_: i don't think the battery is bad at this point, but better be sure by checking with the OF
09:58:19Sparkie_ok yes thank you very much
09:58:26[Saint]Hmmm, nope, the theme is displaying battery in a sane way.
09:59:08[Saint]Odd indeed.
09:59:43Sparkie_hold on guys, my ipod seems to be charging fine now
09:59:51Sparkie_at a proper rate i mean
09:59:56Sparkie_maybe it calibrated by itself
10:00
10:00:01[Saint]Nope.
10:00:06[Saint]Doesn;t work that way.
10:00:18Sparkie_yer yer i know bu ti have no idea what is happening
10:00:37kugelSparkie_: I also think you need a few more charge cycles to reliably tell that the battery runs empty fast. could be that it wasn't fully charged
10:01:23Sparkie_yer sure thank you and i will do
10:01:55Sparkie_my battery is charging at a seems to be normal rate now instead of some stupid % per 2 seconds
10:02:37[Saint]Wait.
10:02:43[Saint]Do you mean *discharging*?
10:02:49Sparkie_no no chargin now
10:03:04[Saint]Ok. Well, that's new information.
10:03:52[Saint]Are we positive about the "loses 1% every 5s" statement?
10:04:02Sparkie_it was before
10:04:12[Saint]Simple math seems to suggest that you'd be getting 8 minutes of battery at that rate.
10:04:19[Saint]I'm willing to believe that wasn't the case.
10:04:54Sparkie_when the screen was on. when it wasn't 80% to 30% shuffling music through earphones for about 15 hours straight
10:05:25Sparkie_saint, it was doing that for a while and then slowing down every now and again and stayed on 0% for about 15 minutes
10:06:45[Saint]How long is "for a while"? Even if it did it for a period of 30s, that's 6% battery lost.
10:06:58[Saint]Is it possible at all that the perception of time was warped?
10:07:46Sparkie_Oh my god dude. I am saying that before, the battery was decreasing fast. But sometimes it would decrease slower
10:08:41 Quit ygrek_ (Ping timeout: 255 seconds)
10:09:31Sparkie_It charged super fast aswell.
10:10:44[Saint]The impression you gave, was that whenever the screen was on the battery would reliably discharge at a rate of ~1% ever ~5s, I'm just trying to ascertain how close to reality that is. Because as noted, at that rate, you've only got 8 minutes of battery with the screen on.
10:11:26Sparkie_yes ok . It was doing that for times, but not all the time
10:11:37Sparkie_that's why i said it fluctuates
10:11:42Sparkie_it's puzzling me too
10:13:41[Saint]It definitely puzzles me. I attempted to configure my iPod in the worst possible way and I can't get anywhere near that kind of discharge rate.
10:13:47[Saint]Something odd is going on.
10:14:11Sparkie_i orignally thought it was a battery that could hold very little charge but i think it must be something else.
10:14:24Sparkie_also do you happen to know how many miiliamphours 7th gen ipods hold
10:14:56[Saint]600, IIRC.
10:15:12Sparkie_ok i think it said 500 on battery stats
10:15:15Sparkie_on rockbox
10:15:38[Saint]That setting isn't related to any battery level displayed to the user at any time.
10:15:48[Saint]That setting is only related to the estimated runtime.
10:15:54[Saint]Which is hilariously inaccurate anyway.
10:16:32[Saint]So, errr, what I'm saying is, changing it will have absolutely no effect.
10:16:39Sparkie_ok yep
10:17:04Sparkie_my ipod charging seems allright now. It might have just taken some cahrge/discharge cycles as kugel said
10:19:01TheSevenanother thing on my todo list...
10:19:13Sparkie_yes?
10:19:24TheSevenfinally figure out where apple is hiding that current sensor so that we can get more accurate battery readings
10:20:09 Join JdGordon [0] (~JdGordon@pa49-183-201-219.pa.vic.optusnet.com.au)
10:20:18Sparkie_Oh cool. theseven are you part of dev team?
10:20:26TheSevenyes
10:20:36TheSevenI'm the ipod nano 2g & ipod classic port maintainer
10:20:50Sparkie_oh my that's really cool
10:21:02Sparkie_ty for the rockbox :0
10:22:09TheSevenSparkie_: I'd *guess* that the battery runtime will be fine, just the meter is probably a bit off
10:22:43TheSevenso if it works for several hours while pretending that the battery would be empty, I just wouldn't worry about that at this time
10:23:05TheSevenif it's very new, it might also be that the battery just hasn't been run in properly yet
10:23:30TheSevenespecially if it has (somewhat likely) been sitting in a warehouse for years before being sold
10:23:50Sparkie_yer I guess. I'll keep rockbox on for like another week or so then change back to apple and if still hasnt fixed i will take back in 30 day warranty babyyyy
10:23:57Sparkie_yer that's true
10:24:44TheSevenanother thing is that the battery won't even try to charge before it's (actually, even if the meter says otherwise) below 80% or so
10:25:11TheSevenhowever plugging it in (and thus removing the load on the battery) will make the meter fluctuate quite a bit even in that area
10:25:42Sparkie_Ok, it just went from 100% to 95% in abuit 10 seconds
10:25:48Sparkie_93
10:25:50Sparkie_92
10:25:55Sparkie_91
10:26:06TheSevenwhat does the voltage reading in the battery debug screen say?
10:26:13TheSeven(system => debug => battery)
10:27:04TheSeventhe percent gauge is nowhere near accurate, it has >10% tolerance in a lot of situations, especially shortly after changing the power source
10:27:18TheSevenit will vastly overestimate the battery state while charging, and slightly underestimate it while discharging
10:27:25Sparkie_view battery?
10:27:29TheSevenyes
10:27:40Sparkie_4.030V
10:27:46TheSevenso if you're just playing with the 80-100% range, this kind of behavior is just normal at this point
10:28:09Sparkie_it's 3.977V atm
10:28:27TheSevenok, it should actually start charging at that point if you plug it in
10:28:59TheSevenhowever the meter will likely just jump straight to 100% if you do so, even though fully charging it from that point would take an hour or so
10:29:24Sparkie_ok it is jumping all over tha place on the view battery
10:29:27TheSeventhis is something that's somewhat likely to get fixed during the next weeks, as I'm currently trying to clean out the last few remaining quirks of the ipod classic port
10:29:36Sparkie_oh cool
10:30:06TheSevenSparkie_: I'd expect it to jump to about 4.15-4.20V if you plug it in, and back to about 4.00V if you unplug it
10:30:15Sparkie_where will that be available from?
10:30:38Sparkie_yer you are right
10:30:45Sparkie_i meant the voltage is jumping
10:30:52TheSevenok, you're just seeing the normal battery meter confusion then ;)
10:31:21Sparkie_pwr status is discharging when it is plugged in?
10:31:22TheSevenyou can't properly tell the exact state of charge from just the voltage, but without access to the current sensor it can't do much better
10:31:57TheSevenyes, that's also just not implemented yet. it will always say discharging.
10:32:08TheSevenanother thing that I already have a fix for, that just didn't go into the official builds yet
10:32:15Sparkie_oh ok. so are you saying my problem is pretty normal but will most likley be fixed next patch?
10:32:23TheSevenyes
10:32:31Sparkie_oh coool dude thanks for that
10:33:13TheSevenI'd expect this kind of things to be fixed in the development builds in about 1-2 months
10:33:30Sparkie_how long should i keep it charging after 100%?
10:33:39TheSevenand once we've reached that point there will very likely also be a new emCORE release which embeds these newer builds
10:34:06TheSevenSparkie_: about an hour should be sufficient to get it close to actual 100%, however it's safe to just keep it plugged in overnight ;)
10:34:32Sparkie_ok yer i might do that
10:35:32TheSevenalso note that if the voltage was above ~4.00-4.05V while plugging in, it won't start charging (you'll see that the voltage goes back up to about 4.1V, but not close to 4.2V)
10:37:40Sparkie_ok so, one last time, the reason my batteyr was discharging fast and then slow may have been because it wasn't fully charged and therefore not at the given percentage?

11:04:07TheSevenSparkie_: techincally not 100% correct, but the behavior is similar, yes
11:04:40Sparkie_ok cool. so what do you think i should do from here?
11:04:46TheSevenactually the battery meter is slightly underestimating the state of charge while discharging, and massively overestimating it while charging (but only if it actually charges)
11:05:08Sparkie_ok and the bettery meter is trying to coirrect itself hence the fast discharge?
11:05:18TheSeventhe meter will "jump" (not instantly, but during a few minutes) between those different estimates
11:05:57TheSevenonce we have current sensor readings, the meter can actually calculate how big these over/underestimations are and correct them
11:06:42*kugel wonders why other targets can get largely-reliable battery readouts without current sensor
11:07:28TheSevenbecause they aren't dealing with 300+ mA discharge current spikes I guess ;)
11:07:42TheSevenor just because nobody cared about the meter accuracy
11:08:25TheSevenbut even on nano2g adding the current sensor to compensate for the battery's internal resistance vastly improved the readings
11:08:52TheSevenespecially during charging, as you just can't tell the battery state from just the voltage if it's charging in the CV phase
11:09:45TheSeventhis one is probably just as "largely reliable" as the others ;)
11:10:53*TheSeven spotted some code in disk mode yesterday that measures the USB D+/D- lines and thus must be dealing with the mux in front of the ADC that is also responsible for battery current measurements
11:13:02TheSeven(this would also enable us to properly detect USB charging spec compliant chargers btw)
11:21:36Sparkie_where will i find the rockbox update if it come sout next month?
11:22:31copperwhere do you usually "find" it?
11:22:38TheSevenhttp://build.rockbox.org/ will always point to the newest development builds
11:22:56TheSevenand if we consider the latest changes somewhat complete and stable, we'll release them on freemyipod.org
11:25:31Sparkie_where would be the ipod classic 7th gen one be though
11:26:12TheSevenhm, looks like the link is missing indeed
11:26:29TheSevenhttp://build.rockbox.org/data/rockbox-ipod6g.zip
11:26:46Sparkie_oh ok ty
11:26:54Sparkie_and this is the latest one with the battery issue/
11:26:56Sparkie_?
11:27:12copperthere's a battery issue?
11:28:08TheSeventhis is the most recent development build, which doesn't have any battery meter and charging state detection improvements yet
11:28:23TheSevenI guess these will go in there within the next month though
11:28:49Sparkie_ok yer i had this on before but i changed to the one from rockbox utility after the battery issue
11:29:54TheSeventhe rockbox utility will do nothing else, it will just download that file ;)
11:30:29Sparkie_hmm ok. looking at the graph on view battery on my ipod, the gradient at which the battery is decreasing is really steep
11:31:33Sparkie_even after charging for over anhour after 100% is this normal?
11:33:16Sparkie_oh wait that's voltage my bad
11:35:55Sparkie_anywaays im of ty for the help. I'll look forward to seeing new rockbox. goodbye

13:29:35wodzhmm, we have duplicates in MODEL_NUMBER - hm60x, clip zip 79; xfi2, hm801 82; xfi3, ma9 83; ma9c, yp-z5 84; zenv, ihifi760 92; android, nokian8xx, nokian900, pandora, yp-r0, sdlapp 100
13:29:43wodzI guess this is not good
13:29:50mortaliswodz: IIRC MODEL_NUMBER used in bootloader to check compatibility of bootloader and main binary, and target_id is the same thing but for voicefiles
13:31:54wodzso we shouldn't have duplicates in MODEL_NUMBER
13:32:06wodzit doesn't make much sense for app builds also

13:35:29wodztarget_id is exported as TARGET_ID
13:39:10mortalischanging MODEL_NUMBER might be a prblem for some targets, as it will require to release new bootloaders
13:39:36wodzyes
13:42:53wodzI wonder why there are two distinct numbers while vast majority of targets have this unique

14:11:16wodzwhat you mean apps?
14:11:42pamaurycodecs, plugins, voicefiles
14:11:52pamauryI think each codec and plugin has the target id in the header
14:12:19wodzok, but why it needs to be different then MODEL_NUMBER?
14:12:36wodzwhy two separate numbers

14:15:02pamauryok, so there might be power/hp gates controlled by gpio ?
14:15:28wodzcould be
14:16:14pamauryalso the model_num is in two places: configure and target config file
14:16:32pamaurybecause some targets don't use it except for rolo
14:17:28pamauryalso the scramble tool doesn't always make use of the model_num values, like for RKW I think

18:04:48TheSevencopper: which way does that adapter get inserted into the ipod?
18:04:48TheSevenwith the CF card towards the front or the back?
18:05:18copperhaha
18:06:04coppererm
18:06:12copperI'm trying to figure out a way to explain it
18:06:27copperbut basically the ZIF interface should give you a clue
18:06:35copperit's not perfectly in the middle
18:06:58copperhttp://outpost.fr/tmp/qrM.jpg/
18:07:09copperthat side should go against the back
18:07:17copperthe back case*
18:07:43copperyou won't be able to plug in the ZIF ribbon if you install the adapter the wrong way
18:09:01copperin other words, the adapter should be facing you like in the picture, with the front side of the ipod (with the display) against the table
18:09:19copperdunno if that's clear enough :P
18:10:02copperthe top left end of the adapter will make it fit snuggly in the front case
18:10:38copperit's designed to fit the case so it doesn't move around
18:11:06copperyou're supposed to remove the two blue bottom "bumpers"
18:11:09TheSevenok, so unlike the HDD, the adapter gets plugged with the contacts of the ZIF ribbon cable facing towards the top of the connector?
18:11:49coppernot sure what you mean, but yes, it's installed differently from the HDD
18:12:04copperyou'll know it when it fits
18:12:44copperI took pictures but I was stupid and deleted them
18:13:11TheSevenok, that little piece of metal that holds it in its position makes it more clear
18:14:38copperI don't suppose you're going to close the ipod anyway?
18:15:10TheSevenyeah, just didn't want to insert it the wrong way round, as the ZIF connector might have pins on both sides
18:15:25TheSevenand it's kinda convenient that the battery is accessible on the top side
18:15:29copperlike I said, it's conveniently off-center
18:16:13copper16:15:26 UTC <TheSeven> and it's kinda convenient that the battery is accessible on the top side
18:16:16copperwhat do you mean?
18:16:28TheSevener, damn
18:16:32TheSevenwhat did I type
18:16:35copperthe battery should be glued to the back case, not the front case
18:16:36TheSevenI meant the CF card
18:16:44copperah
18:16:47TheSevenwas just plugging the battery while typing that :P
18:16:59TheSevenhm, surprise
18:17:02copperyes, so you can insert an SD card without removing the adapter
18:17:12TheSevenI just tried to plug a microdrive into it just out of curiosity, and it doesn't work (ata error 5)
18:17:44copperit wouldn't be any fun if it worked!
18:18:17TheSevenhm, interesting
18:18:27TheSevenwith just the adapter without a card, I don't even get an error
18:18:28[Saint]Seems a bit of a unnt gesture to get east access to the card without renovi the adapter considering how you have to get to the adapter in the first place.
18:18:30TheSevenit pretends to work
18:19:09coppertoo many typos!
18:19:10[Saint]s/unnt/cute/ no idea what autocomplete did there.
18:19:21[Saint]*easy
18:19:44[Saint]*removing
18:19:55*TheSeven needs to remove that empty battery detection code again
18:20:36TheSeventoo inconvenient to actually connect the battery! :P
18:22:13copperI can't remember, did you determine if it was the ZIF adapter, or the CF adapter, that used up too much current?
18:22:28TheSeventhe ZIF adapter is completely passive
18:22:32TheSeventhat's just a connector adapter
18:22:43copperhmmm
18:22:52copperhave you tried a CF card?
18:22:56copperwithout the CF adapter
18:23:12TheSeventhat's one of the things that I'll experiment with
18:23:22copperfor a while I couldn't decide if I should buy a CF card instead of an SD card
18:23:44copperbut the CF cards are a lot more expensive, even when used
18:23:47copper(second hand)
18:25:00copperand I figured that I didn't need the extra performance, since I would only access it over USB anyway
18:26:26[Saint]If you're not doing bulk transfers often, the extra performance is rather wasted.
18:26:52[Saint]Roxkbox would certainly never make use of it at all during playback.
18:27:32[Saint]Its rather surprising how slow "fast enough for lossless realtime" actually is.
18:33:51copperindeed

21:02:59[Saint](I used the supplied build too...cos, honestly, fuck sorting out getting the patch set to compile with the Rb toolset.
21:03:43[Saint]But the backlog suggests wodz got a lot further than I did in battling compile errors.
21:03:51[Saint]And, to no avail it seems.

21:09:37wodzTheSeven: can usb_dw_get_max_transfer_size() be called agains ep0 ? If so this is plain wrong.
21:09:59TheSevenno, that function is completely counter-intuitive
21:10:16TheSevenit returns the number of packets that can be sent at once on a bulk endpoint
21:10:21TheSevennot the number of bytes
21:10:25wodzoh
21:11:03TheSevenwell, not quite sure what it's supposed to do in rockbox, but that's what it's doing, and it seems to work on the classic ;)
21:12:34wodzTheSeven: anyway http://pastie.org/9317612 makes it compile cleanly with rb gcc and I think should be correct
21:12:57TheSevenyeah, as kugel said we should get rid of those bitfields regardless
21:13:01TheSevenor at least the hw-related ones
21:13:23TheSeventhanks for pinpointing the cause of that error though :)
21:14:27wodzTheSeven: yeah, I am all for this but this is a lot of work to debitfildize the driver
21:18:21TheSevencopper: seems like I can reproduce your behavior with a 32GB sandisk extreme SDHC card
21:18:41TheSeventhat's the only card that I have that exhibits this problem though
21:19:30gevaertsIs it the only one that claims to be extreme?
21:19:40gevaertsYou can only expect such cards to be outliers :)
21:22:22wodzgevaerts: Could you comment maybe my question why there are two different numbers describing target in our build system? (I mean MODEL_NUMBER in target's config .h file and target_id in configure)
21:22:38gevaertswodz: I have no idea
21:22:44copperTheSeven: do you mean that, you have other sandisk cards that work?
21:23:10copperor rather: what cards did you test, that do work?
21:23:11TheSevenno, it's the only sandisk card that I have
21:23:16TheSevenfrom what I can tell the CF adapter's firmware is locking up somehow
21:23:30TheSevenit doesn't recover until a power cycle even if I swap the card
21:23:30wodzgevaerts: Who may I ask about this?
21:23:41gevaertswodz: someone who was around before me :)
21:23:47gevaertsZagor, maybe?
21:23:50TheSevennot sure if it's supposed to handle swapping cards during operation though
21:23:58gevaertsPossibly amiconn?
21:25:09wodzamiconn is rather inactive and hard to catch
21:31:15*TheSeven wonders how it can be possible that we lock up that adapter with only some SD cards, but it still works fine with the very same card in a card reader
21:32:38copperwhat works fine
21:32:42copperthe CF adapter?
21:32:45TheSevenyes
21:32:55TheSevenif I put it into a CF card reader, it works just fine with the sandisk card
21:33:00TheSevenlike it did for you with the original firmware
21:33:09TheSevenbut emcore somehow locks it up
21:33:19TheSevenbut only with the sandisk card. hm...
21:33:19copperthere's still the tarkan adapter between the two
21:33:33TheSeventhat adapter isn't more than a few pieces of wire
21:33:34copperyou didn't answer my question: what cards work for you?
21:33:47TheSevensome old 256MB noname crap
21:34:18TheSeventhe 2GB minisd card doesn't work in a card reader either and behaves differently (as if no card was plugged in at all) in emcore
21:34:39wodzwait isn't tarkan cf<->sd thing? If so there must be mcu inside (or cpld/fpga)
21:35:02copperit's zif → cf → sd
21:35:04TheSevenwodz: it's a passive ZIF => CF adapter + active CF => SD adapter
21:35:19TheSevenand the CF => SD card works in a card reader with the very same card that fails in the classic
21:35:33wodzoh, thats weird
21:36:21copperthat fails with emcore*
21:36:32 Quit bcobco ()
21:37:12TheSevenit must be some compatibility thing that involves *both* sides of the adapter
21:37:14copperalso note that the first thing I did, was to format the entire sd card as FAT32, labeled "iPodClassic", then I put the card into the adpater
21:37:51TheSevencopper: the working lexar card had roughly the same capacity as the failing sandisk one, both way above 32GB, right?
21:38:08TheSevendisabling DMA doesn't help at all
21:38:16copperhttp://outpost.fr/tmp/DCi.jpg/

21:45:04TheSeven[Saint]: do you have the required tools to figure out where the pins inside the CE-ATA ZIF cable end up?

22:02:06TheSeveninteresting... I can trigger the very same behavior by unplugging and replugging an otherwise working card on the fly
22:02:51TheSevenanother side note: the adapter doesn't seem to support LBA48
22:03:41TheSevenso 128GB is the maximum card size that it can possibly support

22:13:15woTheSeven: As it seems that ipod side is the same in thick and thin I'd be more interested to see where sdio signals are mapped on 40pin connector
22:13:32 Quit Misanthropos (Ping timeout: 272 seconds)
22:13:45TheSevenwo: yes, but I only have access to one half of that mapping
22:13:53TheSeveni.e. I don't know where which SDIO signal is on the ipod side
22:15:08woTheSeven: why do you need to know this? You need to know where it ends up on 40pin 'hdd' flex' side
22:15:23TheSevenyeah, but I can only track ipod => 40pin here
22:15:31TheSevenbut what I actually need to do is track ceata => 40pin
22:15:50TheSeventhe only way how I can do this is tracking ceata => ipod => 40pin
22:16:10wocan't you drive sdio and look with scope on 40pin?
22:16:54TheSevenpossibly, if I had a scope that's fast enough. it's also a bit hard to tell produce any signal at all on the data pins as long as nothing responds on the CMD pin

22:17:08TheSeventell it to produce*
22:18:20wook, so the only way is to compare mapping of thick and thin flex cable
22:18:29TheSevenyes
22:18:40TheSevenI can figure out the mapping of the thick one, and where the CEATA identify pin is
22:18:44TheSevener, thin one
22:18:51TheSevenI need [Saint] for the thick one

23:53:12kugelhm the build client fetches all remotes between each build
23:53:21kugelwhy that?
23:54:40[7]hm, as in checks for new versions of them?

23:55:51kugelyes. i don't know if it would also actually check out new commits that happen in the meantime though
23:56:22kugeli have 4 remotes, and fetching them takes a significant amount of time if the internet connection is congested due to build uploads
23:57:25[7]hm right, between each build is nonsense, I was thinking at the beginning of each round, which seemed to make sense
