Concerning type traits, the C++ standard states: "The behavior of a program
that adds specializations for any of the templates defined in this subclause is
undefined unless otherwise specified."
There is no exception for is_integral.
`PC_LIBTORRENT_RASTERBAR_CFLAGS` not only gives you the definitions, but
also includes the include path flags (`-I...`).
This causes problesm when passing the result to
`target_compile_definitions`. The resulting compiler command would then
look something like this:
/usr/bin/c++ -D-I/home/...
This change uses `PC_LIBTORRENT_RASTERBAR_CFLAGS_OTHER` instead which
does not contain the include path flags.
Most status alerts should have priorities above normal level. Good reason for this is resume data verification case. For a large torrent(having lots of pieces) whole alert queue will be overflowed
with a `piece_finished_alert` right after resume data has been verified. Thus alerts like `torrent_checked_alert`, `torrent_finished`, `state_changed_alert` will not go the alerts queue.
* Introduce alert_priority enumeration
* Bump state_changed_alert's priority
* Set dht_direct_response_alert priority to `critical`
This cuts down on the number of atomic loads while also being more correct.
Before it was possible for m_num_idle_threads to increase before its value
could be stored in m_min_idle_threads.
Calling blocks_flushed can cause the piece entry to be freed so its
callers need to be aware of that and avoid dereferencing the pointer if
the entry is freed.
If `default_storage::has_any_file` fails during fastresume data check, `piece_manager::check_no_fastresume` will skip storage initialization. In such case, any storage operation that require part file will cause an application crash.
Versions of boost as recent as 1.63 do not create a stub alias for python3
which causes build failures if no version of python3 is configured.
Duplicate that behavior so that building works even on older versions of
boost.
