Does this reproduce on 1.1 or 1.2?

Comment 2

[sarsenyev]

After further research I noticed the issue reproduces only with my Memory SD card, seems like my memory card is corrupted it doesn't reproduce on 1.3 with another memory card

Well, that implies there might be a bug here, but it's just dealing with a specific setup with your SD card. We should investigate this more.

I was able reproduce the issue when launched a video file on another 4GB SD card on 1.2 
But I cannot reproduce it on 1.1, video is allowed to be played on the device when USB cable is attached and USB storage is enabled

A few questions:

(1) Does the SD card where you are seeing it have any unsupported files on it?
(2) Is the SD card close to being full?

I wasn't able to reproduce it with 2 different SD cards using the latest 1.3 build. I tried pulling out the cable while videos were playing as well and didn't see any issues with 1.3

1) I tried both ways with supported and unsupported files, it's easy to reproduce on 1.3 when launch a video file and then connect and disconnect USB cable, I used for the test two 4GB Memory cards, I couldn't reproduce it with 2 GB
2) No the SD card is not full and not even close

I can reproduce this 100% with the following steps:

1) Update a Buri to BuildID: 20140124004002
2) Enable USB storage on the device in settings.
3) Connect the device to a computer via USB.
4) Open the gallery app on the device.
>> The Memory card in use message will display.
5) On the computer dismount and format the SD card to something other than FAT (See video)
6) Disconnect the device from the computer

The issue seems to occur when the device cannot access the SD card, whatever the reason.

[hyeyoung1024.kim]

on MADAI Device(B2G 1.4), This issue is reproduced.

The steps are the below.


==================================
Precondition :
1. Enable USB storage (from settings)
2. Enable Share using USB (settings -> Media storage)
3. Should have some videos in SD card

Steps to reproduce:
1. Open video application and Play a video
2. Plug-in the USB cable
3. When the "Video can not be watched while plugged in / Unplug the phone to watch videos" pop-up
is shown immediately remove the USB cable
4. Issue: The pop-up is still shown even after removing the USB cable

this is easily reproduced.

Please refer attached the video "Video_App_Reproduced.mp4"

also, I attached the log.

==================

If you check the log I attached, you can find that The state was not changed to "unmount" when connecting usb cable.

 
* Success Case.

******* it did not do "unmount volume", Even though usb cable was plugged.

******* So, Volume sdcard1's previous state is still left " Mounted" at this time.

================================






When I checked "AutoMounter.cpp", (http://dxr.mozilla.org/mozilla-central/source/dom/system/gonk/AutoMounter.cpp)
There is nothing to do in this conditions "tryToShare is 0, volState : STATE_MOUNTED".

=======================================================================
void
AutoMounter::UpdateState()
{

....
 if ((tryToShare && vol->IsSharingEnabled()) ||
        vol->IsFormatRequested() ||
        vol->IsUnmountRequested()) {

....
}else{
 // We're going to try and unshare and remount the volumes
      switch (volState) {
        case nsIVolume::STATE_SHARED: {
          // Volume is shared. We can go ahead and unshare.
          LOG("UpdateState: Unsharing %s", vol->NameStr());
          vol->StartUnshare(mResponseCallback);
          return; // UpdateState will be called again when the Unshare command completes
        }
        case nsIVolume::STATE_IDLE: {
          if (!vol->IsUnmountRequested()) {
            // Volume is unmounted and mount-requested, try to mount.

            LOG("UpdateState: Mounting %s", vol->NameStr());
            vol->StartMount(mResponseCallback);
          }
          return; // UpdateState will be called again when Mount command completes
        }
        default: {
          // Not in a state that we can do anything about.
          break;

}
}
}

Dear, Jason Smith.

you are not in charge of this area?

Is it needed to request to other mozilla engineer for investigating this issue?


The reason why I'm asking you is because you canceled Flags(needinfo?).


Thanks.
