* MtpServer: Fix concurrent access to mStoragesTom Marshall2016-06-071-2/+4
| | | | | | | | | | | * getStorage is called both internally with mMutex held and externally without mMutex held. Create getStorageLocked for internal use and make getStorage a wrapper. * hasStorage is only called internally with mMutex held. Make it a private method.

* MTP: Add extended operations to support in-place editing of filesMike Lockwood2011-04-221-1/+22
| | | | | | | | | | | | | | | | | | | | | | MTP does not support partial writes of files (the entire file must be transferred at once). This makes it impossible to implement a FUSE file system for MTP with acceptable performance. To fix this problem, this change adds extended MTP operations to allow partial writes to files: SendPartialObject - allows writing a subset of a file, or appending to the end of a file TruncateObject - allows changing the size of a file BeginEditObject - must be called before using SendPartialObject and TruncateObject EndEditObject - commits changes to a file after it has been edited with SendPartialObject or TruncateObject We also add GetPartialObject64, which is the same as GetPartialObject but has a 64 bit offset rather than 32.

* MTP: Add support for reserve storage setting to avoid low storage situations.Mike Lockwood2010-12-121-1/+1
| | | | | | | | | | | | | Set resource config_mtpReserveSpaceMegabytes to number of megabytes to reserve. If MTP has dedicated storage this value should be zero, but if MTP is sharing storage with the rest of the system, set this to a positive value to ensure that MTP activity does not result in the storage being too close to full.

* MTP: Implement GetPartialObject commandMike Lockwood2010-11-231-0/+1
| | | | | | | Allows host to read partial contents of files on the device Change-Id: I74927f7394224d674e1d150a4b72a51d9358459b Signed-off-by: Mike Lockwood <lockwood@android.com>
* MTP: Partial implementation of the GetObjectPropList commandMike Lockwood2010-11-151-0/+1
| | | | | | | | | | In this initial implementation we only support fetching one property at a time. Support depth = 0 (single object) or depth = 1 (all objects in a directory) Reimplemented GetObjectPropValue on top of GetObjectPropList, since the former is a special case of the latter.

* Integrate host to device file transfer with the media provider.Mike Lockwood2010-07-121-0/+1
| | | | | | | | | | | | | | | | | | | | | MTP file transfers happen in two stages. The SendObjectInfo command sends some information about the file and reserves an ObjectHandle for the new file. The file transfer is then performed using the SendObject command. To support this in the media provider, MtpDatabase.beginSendObject receives the information from SendObjectInfo and creates an row for it in the MTP objects table for the new file. After the file transfer has completed, then MtpDatabase.endSendObject is called. In endSendObject, we run the media scanner on the new file, which will add a row to the images, audio, video or audio playlist table. To avoid the media scanner creating a second row for the file in the MTP objects table, we pass the ObjectHandle created in beginSendObject to the media scanner, which then passes it to the media provider via the content values when it performs its insert.

* MTP: Use media provider database to implement MTP device support.Mike Lockwood2010-07-081-7/+4
| | | | | | | | | | | | | Uses a new "MTP objects" table in the media provider to support basic enumeration of the external storage file system. Support for accessing audio, video and image metadata in the existing media provider tables will be added in a later commit. The C++ MtpDatabase class is now abstract, to support a proxy subclass that calls through JNI to the Java MtpDatabase class in the media provider.

* Checkpoint work on MTP and PTP investigation.Mike Lockwood2010-05-131-0/+86
This change includes work in progress on a C++ library for both host and device MTP and PTP support. Currently the makefile builds two test programs: mtptest - a command line test program that implements a small subset of device side MTP. Requires a kernel driver that has not been checked in yet. ptptest - a host tool to test USB host support for detecting and communicating with digital cameras over PTP. Runs on Linux host. Later this will be reformulated as a native library that will be used in the media process. Change-Id: I81aab279975b600b59d99013ab97f9adf0b58da7 Signed-off-by: Mike Lockwood <lockwood@android.com>
