When torrent size is smaller than the image width, bytes per pixel was
set to zero and code was crashing. Set it to -1 instead, as we do when
image is empty. This will disable highliting, but our algorithm does not
work in this case anyway.
Now getting piece information for a specific torrent is possible via:
* Returns an array of states (integers) of pieces in order. Defined as:
"0=not downloaded", "1=downloading", "2=downloaded".
GET /query/getPieceStates/<torrent_hash>
* Returns an array of hashes (strings) of pieces in order:
GET /query/getPieceHashes/<torrent_hash>
Apparently, recent version of CMake made PkgConfig stuff scooped and we
need to call find_package(PkgConfig) in FindSystemd.cmake too, the call
in FindLibtorrentRasterbar.cmake, that is always used first, is not
enough now.
* Add another constructor to save a call to proxyFunc when its not needed
note that this call is a virtual function call
* Pass in proxyFunc by const reference
* Move get methods together
Looking for incomplete files in a new torrent by using a pre-generated
directory listing presents several disadvantages:
- It requires us to extract the top-level directory name (in case it
was renamed).
- It requires us to know whether the top-level directory was stripped.
- In the latter case, it may result in recursively traversing the
entire contents of all downloaded torrents.
Calling QFile::exists() individually for each file solves all these
issues.
In so doing, the handling of single-file and multiple-file torrents are
rendered pretty much identical, and can therefore be merged.
Computations for detailed tooltips are not protected against unavailable
metadata, that leads to asserts or crashes. But since those tooltips are
useless in this case, do not show them at all. Inform user that detailed
tooltip becomes available once torrent metadata are fetched.
write() is declared with __attribute__ ((__warn_unused_result__)) and as
such we shall check its return value. Took opportunity and adjusted
error reporting a bit: if writing to stderr fails, try to write to
stdout.
Because AddNewTorrentDialog is a sheet in macOS, repositioning it causes bad things to happen, particularly if the main dialog is on a secondary monitor.
