We currently implement our own versions of these on mingw because that platform doesn't have them... but why reinvent the wheel; libevent has already done the same thing. Let's use libevent2's implementation.
has already done it for us.
When seeding on a private tracker, ocelot omits other seeds from the list of peers returned. We can test for this and update our "seed probability" field accordingly.
This commit adds a set of package-visible structs and functions to allow delegating announces and scrapes to different protocol handlers. (Examples: struct tr_announce_request, struct tr_announce_response, struct tr_scrape_request, struct tr_scrape_response.) HTTP is the only protocol handler currently implemented; however, this provides a clean API for other protocol handlers, and having this in trunk will help shake out any bugs in this refactoring.
In addition, logging via the TR_DEBUG_FD environment variable is vastly improved in the announcer module now.
1. make some accidentally-public functions/variables private
2. comment out tr_generateAllowedSet() since we're not using it
3. argument list indentation
The problem was reported by Rolcol and tracked down by livings124. It's flashing orange because the completion in "availability" doesn't match the completion in in "progress", which corresponds with tr_torrentAvailability() and tr_torrentAmountFinished(). tr_cpGetAmountDone() was recently reworked in r12012 for #4048, which caused the problem. Both functions need to sample the torrent using the same methodology so that their results can be used together.
The EV_READ callback allocates a buffer, but then returns without freeing it if recvfrom() returns <= 0. This commit inverts the logic to avoid returning until the buffer's been free()d.
This handles converting the data in a sockaddr_storage to a tr_address + port, and removes redundant code from fdlimit.c and tr-udp.c that previously did this work.
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.
