Deleting a video doesn't delete the .png in the data directory

I deleted a bunch of recorded videos today but when I looked in the video data directory I found that the backend had left behind a bunch of pngs for those deleted videos. From the #mythtv-users channel:

  • <xris> warlord: yeah. but I've never seen that happen
  • <xris> or not happen...
  • <warlord> It happened to me this morning
  • <warlord> using trunk/r13508
  • <xris> hmm, I actually do see a couple of stray png files in mine, too.
  • <xris> sounds like a bug

Are the png files for the recordings you deleted right then or for older recordings? Do the ownership and/or permissions on these png files differ from the settings on your other png files?

You may have had something like the following in your logs, can you supply the log output from when you deleted these recordings and the png files remained behind?

Running r14147, I noticed today that after running on my recordings to be able to readily identify them, deleting them once they had been pulled off the box failed to delete any of the thumbnails, but did delete the recording.

Before renaming the files, I've not noticed any big problems with the thumbnails being automatically deleted. I have occasionally found stranded thumbnails, but haven't checked into it further.

Attached is a patch, mythtv-spaces_in_png_filenames.patch, which allows the code in mainserver.cpp to find all PNG previews associated with a recording even after the user renames the recording file with and includes spaces or semicolons in the filename. I couldn't find any way to escape the spaces/semicolons in the namefilter for QDir, so I just replaced them with the ? (match any character wildcard).

Resolution: fixed
Status: newclosed

(In [15397]) Allow MainServer::DoDeleteThread?() to find all .png files for a recording by replacing spaces and semicolons in the search spec with a question mark so that QDir can find them.

Closes #3522 using patch by Michael T. Dean. References #3779 and commit [15394] since that patch used the same logic in mythtranscode to rename png files.
