This way all the qualifiers (`const`, `volatile`, `mutable`) are grouped
together, e.g. `T const* const x` vs. `const T* const x`. Also helps reading
types right-to-left, e.g. "constant pointer to constant T" vs. "constant
pointer to T which is constant".
There're places where manual intervention is still required as uncrustify
is not ideal (unfortunately), but at least one may rely on it to do the
right thing most of the time (e.g. when sending in a patch).
The style itself is quite different from what we had before but making it
uniform across all the codebase is the key. I also hope that it'll make the
code more readable (YMMV) and less sensitive to further changes.
Test socket validity by comparing to TR_BAD_SOCKET instead of various
(and sometimes wrong) other tests like `x >= 0`, `x != -1`, `x > 0`,
`x > -1`, `x` (valid), and `x < 0`, `x == -1` (invalid).
1. add the option the code to be used under GPLv2 or GPLv3; previously only GPLv2 was allowed
2. add the "proxy option" as described in GPLv3 so we can add future licenses without having to bulk-edit everything again :)
3. remove the awkward "exception for MIT code in Mac client" clause; it was unnecessary and confusing.
max-open-files might have been a nice configuration option once, but (1) we've never advertised it in the gui apps, and (2) the crazy cases are causing more trouble than this feature is worth. It's more complicated now after #4164 -- see #4294, #4311, and this ticket.
existing_dir: An ancestor of filename which must already exist and won't be created by tr_fdFileCheckout(). In implementation this is the download directory and prevents directories from being created in error, such as a mount point for an external drive when the drive is unplugged.
r11813 fixed the timestamp issue by fsync()ing files before close()ing them in tr_close_file(). This causes a little overhead as even read-only files cause a sync as their atimes are modified. Instead, we should call fsync() further back in the call chain in tr_fdFileClose() so that we can know to only sync torrent files that were opened with write access.
fsync() doesn't exist on Windows. bencode had a private function, tr_fsync(), that is a portability wrapper around fsync() on *nix and _commit() on win32. Make this function package-visible, rather than private, so fdlimit.c can use it too.
The Berne Convention says that the copyright year is moot, so instead of adding another year to each file as in previous years, I've removed the year altogether from the source code comments in libtransmission, gtk, qt, utils, daemon, and cli.
Juliusz's copyright notice in tr-dht and Johannes' copyright notice in tr-lpd have been left alone; it didn't seem appropriate to modify them.
