The duration of a song can have fractions of seconds
(quote from http://www.upnp.org/schemas/av/didl-lite-v2.xsd):
The format of the duration string is:
H+:MM:SS[.F+], or H+:MM:SS[.F0/F1]
Where:
+H one or more digits to indicate elapsed hours,
MM exactly 2 digits to indicate minutes (00 to 59),
SS exactly 2 digits to indicate seconds (00 to 59),
F+ any number of digits (including no digits) to indicate fractions of seconds,
F0/F1 a fraction, with F0 and F1 at least one digit long,
and F0 < F1.
The string may be preceded by an optional + or - sign, and the
decimal point itself may be omitted if there are no fractional seconds digits.
Until now, a duration with fractions of seconds could not be parsed and
resulted in an unknown duration. Only durations in the format "H+:MM:SS"
were feasible. This commit enables to read durations in the first format,
i.e. "H+:MM:SS[.F+]"
If a directory is a mount point, omit the "directory: " as well.
This bug is years old, but has become more visible now that mount
points are persistent in the state file.
If `SimpleDatabase::Visit` is called on a database that contains a mounted directry the URIs of the elements passed to the callbacks are not prefixed by the mountpoint path. This leads to lsinfo and add not working because they use the wrong URI. This pull request is using the `WalkMount` helper function to create prefixed versions of `VisitDirectory`, `VisitSong` and `VisitPlaylist` to add the correct prefix to the parameters of the callback functions.
We can do CURL requests asynchronously, and we don't need a
synchronous WorkQueue thread for that.
This allows parallelizing lookups and allows immediate cancellation.
This commit is similar to 788e3b31e1,
and removes more "pure" attributes which were placed on functions that
could throw exceptions, which is illegal according to clang's
understanding of the attribute (but not according to GCC's). GitHub
issue #58 was most likely about StorageDirectoryReader::GetInfo() and
Storage::GetInfo(), which still had "pure" attributes.
Closes#58
