Crash on ejecting backtrace
Crash on ejecting console output Console output of unreliable iPod detection solid-hardware details udevadm info Console output with no MTP plugin and no gtkPod udev rule |

Hi, from the log I see a couple of problems: > amarok: Device supported PMP protocols: ("mtp") and > amarok: Above device suports mtp/usb protocol/driver combo, treating as iPhone (kdelibs <= 4.8.2 work-around) Old versions of kdelibs + udev rules by gphoto2 cause that iPods are misidentified as MTP devices. It seems that Amarok's MTP plugin gets int the way. Could you please try to disable it in Amaork config and retest? > amarok: IpodCollection: IphoneMountPoint: "determined mount-point path to /tmp/kde-madcat/amarok/imobiledevice_uuid_7745856d27a424032b54f315ef4125e3712a76d0" > amarok: IpodCollection: IphoneMountPoint: "created /tmp/kde-madcat/amarok/imobiledevice_uuid_7745856d27a424032b54f315ef4125e3712a76d0 directory" > amarok: IpodCollection: IphoneMountPoint: "calling `ifuse "-u" "7745856d27a424032b54f315ef4125e3712a76d0" "-ofsname=afc://7745856d27a424032b54f315ef4125e3712a76d0" "/tmp/kde-madcat/amarok/imobiledevice_uuid_7745856d27a424032b54f315ef4125e3712a76d0"` with timeout of 10s" > amarok: IpodCollection: IphoneMountPoint: "ifuse: There was an error accessing the mount point: Input/output error" > amarok: IpodCollection: IphoneMountPoint: "ifuse: " > amarok: IpodCollection: IphoneMountPoint: "command exited with non-zero return code 1" This is really strange. Do you have write acces to /tmp/kde-madcat/amarok/? Can you create imobiledevice_uuid_7745856d27a424032b54f315ef4125e3712a76d0 directory below it? You may want to delete /tmp/kde-madcat/amarok/ and let Amaork to re-create it for you. Hi, I toyed with this a bit more and I got the iPod syncing working... well, sort of. I - did a full system update - rebuilt Amarok from source again - deleted /tmp/kde-madcat dir - commented out iThingies related lines in /usr/lib/udev/rules.d/40- gphoto.rules (see below) - rebooted When I disabled the MTP plugin in Amarok, it didn't pick my iPod up at all, complaining that the device doesn't have PortableMediaPlayer interface. When I re-enabled the MTP plugin, the iPod was finally detected . However, any operation performed on the iPod (counting tracks, uploading music etc.) seems to take unusually long now - Amarok needs like 30 secs to probe ~ 700 tracks that I have on the iPod. When new tracks are being copied onto the iPod, "Syncing" message is displayed on its screen for the duration of copying, which also isn't the case of other iPod management software or Amarok 2.5. All other ways of accessing the iPod - gtkPod, Clementine, afc via Dolphin+kio-afc - work normally and I have full access to /tmp/kde-madcat dir. The linked archive contains output of "amarok -debug 2> log" with and without MTP plugin disabled (I'm sorry for the huge size of "amarok_withMTP.log" file). My current gphoto udev rules file is also included. https://dl.dropbox.com/u/37342755/amarokDbg.tar.bz2 (In reply to comment #2) > When I disabled the MTP plugin in Amarok, it didn't pick my iPod up at all, > complaining that the device doesn't have PortableMediaPlayer interface. How did you disable the MTP plugin? I suppose not the way I told you, because that would have no effect on whether PortableMediaPlayer interface is attached to iPod or not. I think you disabled it in a way that resulted in libmtp being uninstalled, here's why: kdelib's solid attaches PortableMediaPlayer interface to every udev device that has non-empty ID_MEDIA_PLAYER property. ID_MEDIA_PLAYER gets set by udev rules of following packages: 1. libmtp that (mistakenly) sets it to 1 even for iPods 2. gphoto2 that tou tweaked and that (mistakenly) sets it to 1 even for iPods 3. media-player-info, the _only_ package that _should_ set it for iPods, it sets it to "ipod", which is the only correct value for ipods Amarok decides based on supportedProtocols() attribute of the PortableMediaPlayer: a) kdelibs <= 4.8.2 always return "mtp" for all values of ID_MEDIA_PLAYER b) kdelibs >= 4.8.3 return "mtp" if ID_MEDIA_PLAYER == 1 and correctly query media-player-info if ID_MEDIA_PLAYER is textual, this results in "ipod" for iPods. > When I re-enabled the MTP plugin, the iPod was finally detected. Side-effect of pulling libmtp. > However, any operation performed on the iPod (counting tracks, uploading > music etc.) seems to take unusually long now - Amarok needs like 30 secs > to probe ~ 700 tracks that I have on the iPod. Please be specific here. I see 2 possible reasons why operations with iPod may feel slow to you: 1. when iPod is connected, Amarok reads cover arts of all albums. (other players probably don't do this) If every of your 700 tracks is from different album, that may be the culprit. I'm interested in improving this, perhaps by reading covers in a background job. 2. when copying tracks to iPod, Amarok calls fsync() after each track to ensure the write buffers have been written back to the device (see bug 139454). This causes that copying in Amarok looks slower, but this is in fact the true speed, other methods give false indication by emplying large write buffer. > When new tracks are being copied onto the iPod, > "Syncing" message is displayed on its screen for the duration of copying, > which also isn't the case of other iPod management software or Amarok 2.5. This is not a bug, this is a feature of the new iPod collection! > The linked archive contains output of "amarok -debug 2> log" with and > without MTP plugin disabled (I'm sorry for the huge size of "amarok_withMTP.log" > file). My current gphoto udev rules file is also included. Plase don't link external storage sites next time, attach files to bugzilla directly. To summarise: 1. the "iPod not connected" problem is caused by missing media-player-info package 2. the "iPod misidentified as MTP device" problem is caused by a bug in kdelibs <= 4.8.2 You may want to bug your distribution to include kdelibs >= 4.8.3 in its update channels, that also should pull in media-player-info package if kelibs are packaged right.

Crash on ejecting console output
I did some extra testing to make sure I didn't report any bogus info. For the record, I have kdelibs 4.8.3 and media-player-info package is also installed. There is a "/usr/share/media-player-info/" dir and an udev rules file in the correct place. I disabled the MTP plugin in Settings->Configure Amarok->Plugins by unticking the "MTP Collection". Now I'm certain that both "MTP Collection" and "iPod & co. Collection" have to be enabled in order for my iPod to be detected. I tried to comment out all entries with "idVendor" set to "05ac" in gphoto and libmtp udev rules, but that made no difference. Is there something else possibly misconfigured in my system? You are probably right about the album covers causing the speed issues. On a slightly unrelated note, Amarok crashed 3 times upon ejecting the iPod. In two cases I didn't modify its collection in any way, in the 3rd instance I changed an album name of one track.

Hmm, very strange, please post the output of: 1. `udevadm info --export-db | grep -A70 /devices/pci0000:00/0000:00:1d.7/usb8/8-2` 2. `solid-hardware details /org/kde/solid/udev/sys/devices/pci0000:00/0000:00:1d.7/usb8/8-2` 3. `amarok --debug` with MTP plugin disabled not recognizing your iPod. You may need to replace /devices/pci0000:00/0000:00:1d.7/usb8/8-2 with updated path, see `amarok --debug` output for path to device that is being probed whether it is iPod or not. I can confirm the crash, it is caused by disconnecting the iPod while it is still reading the tracks, I'll look at it. Git commit 5301ebef4fda42f5ded588516f8644d25caa8383 by Matěj Laitl.

Console output of unreliable iPod detection
Amarok's behaviour is rather inconsistent. Sometimes the iPod is detected, sometimes it's not. I attached a "amarok -debug" log with three attempts to connect my iPod for syncing. First two of them failed, the third one was successful. Please note that I didn't do anything apart from unplugging the USB cable and putting it back in after a little while.
I searched through my udev rules a found a rule I added for gtkPod. The relevant part of the file contains this:
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="05ac", ATTR{idProduct}=="129[0-9]", RUN+="/bin/mkdir -p '/media/i_%E{dir_name}'", RUN+="/usr/bin/ifuse '/media/i_%E{dir_name}' -u '%s{serial}' -o sync,allow_other"
ACTION=="remove", SUBSYSTEM=="usb", ENV{PRODUCT}=="5ac/129[0-9]/*", ENV{INTERFACE}=="255/*", RUN+="/bin/umount -l '/media/i_%E{dir_name}'", RUN+="/bin/rmdir '/media/i_%E{dir_name}'"
When I comment these lines out, the unreliable detection problems seems to disappear. When I re-enable them, the problem is back. My guess is there is some sort of clash between Amarok and that udev rule, both trying to mount the iPod at the same time.
I also had another reproducible crash related to iPod ejection, shall I open a separate bug report for it? The crash I reported before appears to be resolved though, thank you.

Console output with no MTP plugin and no gtkPod udev rule
I just found out that the MTP plugin really must be enabled. Even if I disable the aforementioned udev rule, iPod still isn't detected unless the MTP plugin is enabled. I attached the debug log of that situation. (In reply to comment #12) > I searched through my udev rules a found a rule I added for gtkPod. The > relevant part of the file contains this: > ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="05ac", > ATTR{idProduct}=="129[0-9]", RUN+="/bin/mkdir -p '/media/i_%E{dir_name}'", > RUN+="/usr/bin/ifuse '/media/i_%E{dir_name}' -u '%s{serial}' -o > sync,allow_other" > ACTION=="remove", SUBSYSTEM=="usb", ENV{PRODUCT}=="5ac/129[0-9]/*", > ENV{INTERFACE}=="255/*", RUN+="/bin/umount -l '/media/i_%E{dir_name}'", > RUN+="/bin/rmdir '/media/i_%E{dir_name}'" You should _not_ mount iPod yourself nor you should add any custom udev rules that do it. (alternatively, you can mount it to the place where Amarok would mount it, but I strongly discourage you from doing so; if you do so, you must ensure you mount it as the same user that runs Amarok, otherwise usbmuxd will be started ) Amarok is coded to work for default configuration. You should have mentioned that you have custom iPod udev rule in the first post, that would save me a lot of time I spent debugging your issue. > I also had another reproducible crash related to iPod ejection, shall I open > a separate bug report for it?

After upgrading to Amarok 2.5.90, every time I connect my iPod Touch 1G (jailbroken, FW 3.1.3), I get an error message box which says "Connecting iPhone, iPod or iPod touch failed". Problem is not with the iPod itself, gtkPod, Clementine and Amarok 2.5 work with it just fine. Amarok creates "/tmp/kde-madcat/amarok/imobiledevice_uuid_7745856d27a424032b54f315ef4125e3712a76d0" directory, but when I manually cd to "/tmp/kde-madcat/amarok/" and run "ls", I get "ls: cannot access imobiledevice_uuid_7745856d27a424032b54f315ef4125e3712a76d0: Input/output error" message in the terminal. "ls -l" in that directory returns "d????????? ? ? ? ? ? imobiledevice_uuid_7745856d27a424032b54f315ef4125e3712a76d0". Running "ifuse -u IPODS_UUID /some/dir" manually mounts the iPod correctly. When I close the message box, Amarok displays "Apple iPod" in the left panel with track count showing zero. Amarok 2.5 displayed "MadCatZ iPod" which is the correct name of the device. Reproducible: Always Steps to Reproduce: 1. Start Amarok 2. Connect iPod Touch 3.
