| Summary | 0009940: Regressions in backward WiFi synchronization | ||||
| Description | I briefly tested backward WiFi sync and I found several problems/regressions 1. There was a regression on MMW side in 1604 that is fixed in 1605 (issue 0009939), i.e. in 1604 it doesn't work at all because of MMW 2. Pairing songs based on metadata doesn't work because - 2a) MMA sends the device path with sorage prefix that MMW cannot know if the first communication is just via WiFi, i.e. MMA should send the device path without the storage prefix over WiFi - 2b) MMA doesn't send Artist field in the DIDL XML (regression) - 2c) The whole pairing songs process is executed only when Backward Sync is enabled, it should be performed any time when some new songs (with unknown WiFi ID) are added. e.g. users copy new song to the phone by using another app or via explorer, then MMA should run the pairing process for the song on the next WiFi sync so that it properly gets its WiFi ID. Tech note: if the song doesn't exist in MMW library then MMA should mark such a song (e.g. set WiFi ID = -2) to prevent from trying to pair it on each WiFi sync. 3. MMA->MMW sync of metadata doesn't work, because MMA sends timeStamp="1970-01-16 15:31:14" for each field 4. MMA->MMW playlist sync doesn't work (regresion) a) created new playlist in MMA from synced tracks => no playlists upload request to MMW server b) reordered tracks in a MMA playlist previously synced from MMW => no playlists upload request to MMW server Maybe it is also just the timestamp issue as in case of 3 ? | ||||

3. Not sure if it's related, but I noticed, that everytime I start sync, Updating process goes through all of the previously synced tracks. I'd expect that this happens only for tracks that were somehow updated in the phone, e.g. modified rating or increased playcount. |
|
|
2. fixed in build 56 But I have a question about it. What if user copies the media from MMA device to PC or download the same track on PC ? These tracks won't be matched and synchronized because they would have this "-2" flag. |
|
|
3. fixed in build 56 - fixed metadata upload UI of sync activity still has to be changed to follow the background process |
|
|
5. Sure. This is fix of 2). Every unsynced track is uploaded to MMW for matching. This is done only for the first time. As I wrote I will add progress bar for it to not display the Waiting for response dialog for so long time. |

6. Recently we added new folder configurations on the device config panel, namely on tab [Auto-Sync --> Library] user can configure folders from which the files should be synced/copied. I added the folders to the DeviceConfig.xml, you will find them as <BiDirFolder>\Music\</BiDirFolder> <BiDirFolder>\Video\</BiDirFolder> ... i.e. MMA should copy back only files from these folders There is also one question related to 5. , shouldn't only tracks from these folders be paired? I guess that answer is YES? i.e. files outside these folders like videos from DCIM folder shouldn't be uploaded to MMW for matching. |

4. I have one question about playlists. How to solve situations when playlists contains tracks from more storages. But playlists are synchronized for each storage separately ? |
|
|
7. Add checking of changed metadata during synclist analysis to skip unnecessary updates to DB. |
|
|
4. To be discussed, can probably be deferred for v1.1. 7. Not sure if related to this, but updated metadata from MMW aren't synced. E.g., if I change rating of a synced track in MMW, then Sync, there isn't anything updated in MMA. |

6. fixed in build 58 7. fixed in build 58 |

|
7. Re. rating - there is an issue with sync of rating on MMW side. I sent details to Ludek. |
