Move sideband client side support into reusable form. This moves the receiver side of the sideband support from fetch-clone.c to sideband.c and its header file, so that archiver protocol can use it. Signed-off-by: Junio C Hamano <junkio@cox.net> 2006-09-10 08:06:33 +00:00			`#ifndef SIDEBAND_H`

Prepare larger packet buffer for upload-pack protocol. The original side-band support added to the upload-pack protocol used the default 1000-byte packet length. The pkt-line format allows up to 64k, so prepare the receiver for the maximum size, and have the uploader and downloader negotiate if larger packet length is allowed.

recv_sideband: Bands #2 and #3 always go to stderr This removes the last parameter of recv_sideband, by which the callers told which channel bands #2 and #3 should be written to. Sayeth Shawn Pearce: The definition of the streams in the current sideband protocol are rather well defined for the one protocol that uses it, fetch-pack/receive-pack: stream #1: pack data stream #2: stderr messages, progress, meant for tty stream #3: abort message, remote is dead, goodbye! Since both callers of the function passed 2 for the parameter, we hereby remove it and send bands #2 and #3 to stderr explicitly using fprintf. This has the nice side-effect that these two streams pass through our ANSI emulation layer on Windows.

Move sideband server side support into reusable form. The server side support; this is just the very low level, and the caller needs to know which band it wants to send things out.
