We don't currently (if ever) provide context help, so the button is
useless. Moreover, on Windows 10 it's even larger than before and
sometimes title text doesn't fit because of it.
Since double-click is usually used to open things, don't use it to enter
edit mode, use platform-specific keyboard shortcut instead (Return, F2,
etc).
Add context menu duplicating available actions, resembling that of Mac
client. This includes new "only check selected" action.
Speed up DND/priority change for large numbers of files at once. Make
DND/priority toggling more natural: if both parent and its child are
selected, only act on parent (with all its children following).
Use simple tokenization instead of splitting the file path into
QStringList for each item. Don't expand each added item separetely
during population/update. Don't expand all the items but just up to the
point where parent has more than one expandable child.
Also, fix items order by sorting items after population/update. Fix
sorting by size on systems where uint64_t != quint64.
This avoids blocks corruption in case webseed provides bad data.
As explained by cfpp2p, "The requirements to reproduce are at least one
webseed that sends corrupt block(s), and at least one other peer (webseed
or regular peer) that sends correct data for the same block. Then a peer
with correct block sends the block and transmission accepts and verifies
that block as good. But then the webseed thread comes around and the same
block is downloaded from the webseed that sends a bad block which is then
written even though the piece was previously deemed complete."
This ensures proper network errors formatting on Windows.
Also, disable IP_TOS socket option modification attempts on Windows
since it's not supported there and is considered deprecated: "Do not
use. Type of Service (TOS) settings should only be set using the
Quality of Service API" (c) MSDN. Using QoS API is a subject for
separate commit(s).
Decrypt only what is asked for, not more. This fixes previous commit
which changed semantics by processing the buffer to the very end,
starting with correct offset though.
Refactor encryption/decryption to a single function which callback.
I've misread libevent documentation and the check introduced was not
entirely correct. Changed `evbuffer_peek` call now to only request the
data which would fit into provided iovec.
Recent versions of libevent changed the semantics of `evbuffer_ptr_set`
function in a way that it succeeds if pointer is set right after the end
of the buffer. This caused `tr_cryptoEncrypt` and `tr_cryptoDecrypt` to
be called twice for last buffer chunk since no checks for `evbuffer_peek`
return value were made while it was returning 0 on last loop cycle,
leaving iovec unchanged.
Simplify DND checkboxes drawing, this also fixes incorrect drawing on
Mac when file tree widget is inactive.
Do better job calculating column widths for file tree to avoid ellipsis.
Fix file tree sorting order for size and priority columns.
Change key to toggle priorities to Shift+Space instead of Enter/Return
to avoid conflicts with name editing and default button handling.
Fix selected tracker item background drawing in certain cases.
Split FileTree.{h,cc} and FilterBar.{h,cc} files so that each class
is in its own file.
This breaks translations (some classes got renamed => context changed),
to be fixed by next commit (along with Tx sync).
