* MTP: make MTP work even if unplugged and repluggedEthan Yonker2015-02-024-42/+34
| | | | | | | | Set up a loop to keep trying to open / read the MTP device so that MTP will work even if the device is unplugged during boot or unplugged and replugged in. Change-Id: I0d3a3b7c91ce84a8cbed16caa4b15efee35b3641

* Move sleep during MTP startup to MTP threadEthan Yonker2014-12-291-0/+5
| | | | | | | | | | Some devices are very slow to respond to the sysfs requests. To prevent delaying the main GUI from booting during TWRP startup, we move the sleep delay to just before we open the MTP device and into the MTP thread so that it does not hold up the main TWRP thread.

* MTP add/remove storage instead of disabling MTPEthan Yonker2014-12-1913-17/+248
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a pipe between TWRP and MTP to allow TWRP to tell MTP to remove storage partitions as they become unavailable (e.g. during a wipe, unmount, etc) instead of disabling MTP completely. This includes some fixes and improvements in destructors to properly remove / delete various items. This also means that we will not be toggling adb off and on quite as often. I do not like that we had to add another thread, but we were unable to use select() on the mtp_usb character device because this device does not support polling. Select always returned indicating that the mtp file descriptor was ready to be read and the resulting read would block. The read block prevented us from being able to include reading of the pipe between TWRP and MTP in the main MTP thread. We might want to add a return pipe letting TWRP know if the removal of the storage device was successful, but I am not sure how we want to implement this. It would invovle timeouts in both TWRP and MTP to ensure that we returned a failure indicator in a timely manner to TWRP and prevent deleting the storage device in the case of a failure. Right now we make no attempt to ensure that an MTP operation is underway like a large file transfer, but we were not doing anything like this in the past. In some respects we have limited control over what happens. If the user installs a zip that unmounts a storage partition, we will not know about the change in storage status anyway. Regular Android does not have these troubles because partitions rarely get unmounted like in recovery. At some point, we have to hold the user accountable for performing actions that may remove a storage partition while they are using MTP anyway. Ideally we do not want to toggle the USB IDs and thus toggle adb off and on during early boot, but I am not sure what the best way to handle that at this time.

* Attempt to set the proper uid/gid/contexts on new files and dirsEthan Yonker2014-12-122-2/+5
| | | | | | | | | | Files and folders that we create during backups, copy log, or MTP operations often do not have the proper uid/gid/contexts assigned. We will attempt to read the proper contexts from the settings storage path and assign those same contexts to any files or dirs that we create. Change-Id: I769f9479854122b49b499de2175e6e2d026f8afd

* TWRP MTP: make sure inotify_fd is setEthan Yonker2014-11-251-9/+14
| | | | | | | | | | | Originally the inotify_init() call was part of a separate thread which would occasionally allow the readDirs function to run and start trying to add watches before inotify_fd was init'ed properly and result in the add watch failing. This patch set relocates the inotify_init call to happen outside and before starting the separate thread to ensure that inotify_fd is set properly.
