[Http-crcsync] crcsync, Mozilla, GSoC and students

[Alex Wulms]

Hi Gerv,

Here is what they need:
1) Get sources from http://repo.or.cz/w/httpd-crcsyncproxy.git (note: it is a 
full apache source tree, with the new modules included)

2) take following sources (in unmodified form) from the tree:
ccan/crc/crc.c
ccan/crc/crc.h
ccan/crcsync/crcsync.c
ccan/crcsync/crcsync.h
crccache/crccache.h

3) Copy/paste/modify appropriate parts from following two sources into 
firefox. 
crccache/mod_crccache_client.c
crccache/Makefile

Basically, mod_crccache_client.c is an apache cache handler module. It takes 
care of building the "Block-Hashes" request header and of re-assembling the 
final response from the originally cached file and the encoded data received 
from the upstream server. Because it integrates with apache, you can not just 
take it as is, but you will have to port the code into firefox.
But the good point is that it is build on top of the code in ccan/... folder, 
which is completely re-usable.

Hope that this helps your students already get up to speed.

Note that the code is not yet complete.  It is only a first draft of the 
implementation. There are still several special cases that need to be 
supported. See all TODO remarks in the code and the discussions about the 
protocol specification on this list.

Kind regards,
Alex
