#220 closed Enhancement (fixed)

Lazy Bitfields

Reported by: SoftwareElves Owned by: somebody
Priority: Normal Milestone: 1.40
Component: libtransmission Version: 0.6
Severity: Normal Keywords:


Description found on Always send a faked incomplete bitfield, and instead send remaining completed piece info via Have messages. Certain ISP (ie Cablevision's Optimum Online) networks seem to block peer seeding via "complete" bitfield message filtering. You should only use this option if you need to.

Added to that list of bad ISP is the very popular Comcast, which has cause alot of "my torrent's aren't seeding" in the forum. If i remember correctly, the client sends 12 random undownloded blocks in it's bitfield to each peer when it is seeding.

This would be nice to have... but it's not a blocker IMO

It appears that lazy bitfields are still useful in some circumstances, and it's very easy to implement.

first draft of supporting this is now in r6556.

We'll still need to add support for setting this in the GUIs and in transmission-remote.

The gtk+ and daemon clients can be used with this right now by editing the "lazy-bitfields-enabled" key in settings.json.

This feature has been removed from trunk. Encryption and the "fast" extensions' have_all / have_none messages have made this feature obsolete.

Actually this feature has been broken for quite awhile because anytime we had a seed, a have_all message was sent instead of a lazy bitfield, and nobody noticed...
