Re: Help in Eventio Branch

You need to be familar with the current I/O method using commSetSelect()
and then the actual I/O performed by the callback, and the new eventio
API where eventio takes care of the I/O and then calls the callback.

In the eventio branch most of client_side.c has been translated to
eventio already, but quite a bit of work remains to port the rest. This
involves going thru every location where there is a commSetSelect and
convert it to the eventio API, and to change how I/O buffers are
managed. The concept of I/O buffers did not exists before eventio which
is a bit of a hazzle when making the transition to asynronous I/O.

The eventio branch is downloadable from the SourceForge CVS repository
by the tag "eventio". It should be quite up to date.

  cvs -d... co -r eventio -d eventio squid

Francly I do not know which path is the best. Convert Squid to eventio
or start from scratch and then pull things in to get something that
resembles Squid. Both are major tasks and will take months (in man
hours, not calendar time) to get completed.
